Frequently Asked Questions

Q: In layman's terms, can you tell me how RSE saves energy?

A: RSE saves energy by reducing the wasted energy all over a facility. If there wasn't any wasted energy,
RSE wouldn't be able to save you a cent! Motors, lighting systems, wiring, mechanical terminations, distribution panels, protective devices, transformers, switch gear, and all end of circuit equipment experience a variety of resistance. These inefficiencies combine to create an average wattage loss in a typical facility of more than twenty percent (20%) of the total demand power. RSE works to identify and calculate the sum of the individual contributing loss components and then provide the corrective measures required.

Q: If one EasiLiner can save ten percent (10%) on a motor, will two EasiLiners save twenty percent (20%)?

A: No. Each EasiLiner is optimally selected to function for that specific motor. Adding a second EasiLiner to a motor creates overcorrection, which causes the motor it's treating to consume more reactive power.

Q: How does the EasiLiner reduce the current in the motor circuit?

A: Let us begin by studying the motor current and capacitor current. The EasiLiner reduces the current in the motor circuit as follows:

The motor circuit is comprised of two types of current - Real Current and Reactive Current. The Real Current does the actual work at the motor shaft. This current is perfectly aligned with the voltage waveform.

The Reactive Current does the work that makes the motor rotate. This current is lagging the voltage waveform by ninty degrees (90°). The EasiLiner Current leads the voltage waveform by ninty degrees (90°), creating a difference of one-hundred-eighty degrees (180°) between the EasiLiner current and the motor's Reactive Current, effectively cancelling each other out.

By sizing the EasiLiner correctly, the reactive current is cancelled out and the real current remains unaffected, creating a positive outcome for your Client.

Q: Why do motors run cooler when treated with the EasiLiner?

A: The reason motors run cooler when treated with an EasiLiner is due to the voltage drop across the branch circuit that is feeding the motor. As the full motor current flows through the branch circuit, there is resistance across the line, which reduces the voltage the motor is receiving at its terminals than what is at the source.

Current = I, Resistance = R, Voltage Drop = Vd :: I * R = Vd
Voltage Source = Vs, Terminal Voltage = Vt :: Vs = Vd + Vt
Power (in Watts) = P, Voltage = V :: P = V * I (1 HP = 735.5W to 750W, depending on various standards)

By the EasiLiner reducing this current, this voltage drop is reduced; therefore, the motor terminals get a higher voltage. In order to understand the motor's temperature, we need to assume that the motor is running at its rated load. When motors are running at their rated load, they need to run at their rated voltage. This is due to torque being a function of voltage. When the motor is running at its rated voltage, and suddenly gets less voltage (for whatever reason), then the motor will have less torque. The motor will then draw more current to compensate for this shortfall of torque. This excess current, which will exceed the rated current of the motor, will overheat the motor's windings. This is why some appliance motors burn at home when prolonged brownout condition occurs. By installing an EasiLiner at the motor's terminals, we reduce the current through the branch circuit; therefore, we reduce the voltage in the branch circuit, get better voltage at the motor terminals, drive the motor's load more easily, thereby reducing the temperature of the motor.

Q: The plant Engineer claims that his plant distribution system losses are negligible (less than one percent [1%]). How can we demonstrate that we can help him?

A: Please see the question "How does the EasiLiner save electricity?"

Q: How does the EasiLiner save electricity?

A: Total Power (Tp) = Distribution Losses (Dl) + Power Consumed By Motors (Pm)

The EasiLiner reduces the current through the distribution system, hence reducing the distribution losses in the above equation. Assuming we could eliminate the distribution losses in the equation completely (Dl = 0), then Tp equals Pm.

Q: Can motors with "Run" Capacitors be treated?

A: Single Phase Motors need these "Run" Capacitors to start and run; therefore, they are required to operate. These are not Power Factor Corrrection Capacitors; however, most air conditioning compressors and motors have a fairly high Power Factor and treatment would not bring any significant improvement. Single Phase Refrigeration Compressors and Single Phase Pumps all run at a low Power Factor and can be treated, regardless of those similiar to Start and Run Capacitors.

Q: Is a Run Capacitor the same as a Power Factor Capacitor?

A: The simple answer to this question is NO. Single Phase Motors have two windings. The Starting Window is in series with the capacitor, and while the motor is stopped and first energized, the motor does not create any torque. The current at the Start Winding is phase shifted with the current at the Run Winding, thus creating the Starting Torque.

Q: How do we know what type of Ballasts the lights are using?

A: Ballast Information is generally indicated on the actual ballast; however, as a "Rule of Thumb," the following generally applies:
• With Fluorescent Bulbs, T-12 bulbs are typically magnetic ballasts, while T-10 and lower bulbs use electronic ballasts.
• With HID Lighting above 400W, these are Auto-Regulated Ballasts.
• With HID Lighting below 400W, these are Auto-Transformer Ballasts.

Remember that this just represents a "Rule of Thumb" and variations do occur. If you cannot access the Ballast, we recommend you contact the company that services the lighting of the facility and ask them. Alternatively, you can check with the Maintenance Department or contact the Manufacturer.

Q: What is the difference between Magnetic and Electronic Ballasts in HID Lighting?

A: Electronic Ballasts mainly benefit the Customer because they have less losses than Magnetic Ballasts (Auto-Regulated and Auto-Transformer Ballasts). Magnetic Ballasts have approximately fifteen percent (15%) losses while the losses on Electronic Ballasts can be as little as one percent (1%). Since Electronic Ballasts are expensive, they are not specified in standard fixtures and users will have to purchase them seperately. In such cases, you will have to ask the Maintenance Staff at the Facility if they ordered Electronic Ballasts or kept the original Magnetic Ballasts.

Q: What types of treatment do we specify on different types of Ballasts?

A: Implants: Wall Switches with Magnetic Ballasts
EuroLiner: All Electronic Ballasts
Panel Switching: Treatments vary based on the type of ballasts
IllumiLiner: Panel Switching with Magnetic Ballasts

Q: What is downstream switching?

A: Downstream Switching is where there are switching devices between the Panel and the Lights. Wall Switches or Relay Switches used to operate the lights are a perfect example of Downstream Switching.

Q: Why and how do we apply Surge Supression to a Facility?

A: The direct benefit of applying Surge Surpression is the reduction of the cumulative effect of transients to sensitive electronic equipment. This, in turn, translates to increased reliability and reduced production time. To get these benefits , the TVSS must be installed at the subpanels, on the load side of the main breaker. Please note that the TVSS is sized according to the Voltage of that panel, not its Current.

Q: Can we treat non-linear loads, such as variable speed drives, welders, and DC motors?

A: Yes, we can treat non-linear loads, but we need to get the following actual measurements from the line side of your non-linear load before we can: Voltage, Amperage, THD Current, THD Voltage, kW, and KVAR.

Q: What is a syncronous motor?

A: A synchronous motor consists of a DC-powered magnetic field rotor. Once the motor has started, the DC field follows the rotating AC electromagnetic fields in the stator; therefore, the mechanical speed is going to be synchronos with the line frequency. For example, a two (2) magnetic pole rotor has a mechanical speed of 3600 rpm. For a four (4) magnetic pole rotor, the mechanical speed is 1800 rpm. Since the mechanical speed is synchronous to the electrical frequency, the motor is called a synchronous motor. These types of motors cannot be treated because increasing or decreasing the intensity of these rotating DC fields, Power Factor can only be adjusted to unity.

Q: What is Power Factor?

A: Figure 1: Power Factor Triangle Power Factor (PF) involves a relationship between two types of power, Reactive and Working. In Reactive Power, there are two types of load components, Inductive and Capacitive. Most loads in modern electrical distribution systems have an Inductive Component, meaning that they require an electromagnetic field to operate; therefore, modern electrical distribution systems have the following characteristics:

• Working Power is measured in kilowatts (kW) and performs the actual work of creating heat, light, motion, etc.
• Reactive Power is measured in kilovolt-amperes-reactive (KVAR) and doesn't do useful "work." It simply sustains the electromagnetic field.

The combination of Working Power and Reactive Power makes up Apparent Power, which is measured in kilovolt-amperes (KVA). The "Power Triangle" (Figure 1) illustrates the relationship between these three (3) types of power. Since this relationship is, in fact, a right triangle, the Pythagorean Theorem applies, yielding the following equation:

Apparent Power (Pa), Working Power (Pw), Reactive Power (Pr) :: (Pa)2 = (Pw)2 + (Pr)2

Finally, PF is a numerical ratio from 0.0 to 1.0 of the Working Power to the Apparent Power (or kW / KVA). PF can also be expressed as a percentage of overall efficiency, where 0.0 = 0% and 1.0 = 100%, yielding the following equation: PF = Pw Pa


Q: What does Power Factor actually measure?

A: Power Factor measures how effectively electrical power is being used. A high Power Factor means that electrical power is being used effectively, while a low Power Factor indicates poor use of electrical power.


For example, a Paper Mill that was operating at 100 kW (Working Power) and the Apparent Power consumed was 125 KVA. Plugging this into the PF equation above yields the following:

PF = Pw ÷ Pa = 100 kW ÷ 125 KVA => PF = 0.8 or 80%.
This 80% PF represents a fairly low Power Factor for a facility.

Q: Why should I be concerned about low Power Factor?

A: A low Power Factor means that you are not fully using the electrical power that you are paying for. In the example above, the Paper Mill only had an 80% Power Factor, which means that it was only using 80% of the energy supplied to it by the Utility Company to do useful work. This also means that 20% of the energy purchased from the Utility Company is lost, but still being paid for by the Client. Normally, this lost energy is converted to heat and introduces another undesired load to your Air Conditioning System.

Q: What can I do to improve the Power Factor?

A: The simplest way to improve the Power Factor is to add Power Factor Correction Capacitors to the Inductive Components in your electrical system, which is primarily the motors. Power Factor Capacitors act as Reactive Current Generators and must be properly matched to each component so as to not overcorrect the problem, such that the KVAR of the motor is approximately the KVAR of the Power Factor Capacitor. By providing the proper amount of Reactive Current to each component, the Apparent Efficiency of the Component is improved, i.e. a higher Power Factor, and the total amount of Current your system draws from the Utility Company is reduced.

Q: How much can I save by installing Power Capacitors?

A: The answer depends on the exisiting Power Factor. The lower the existing Power Factor, the higher the savings. In general, adding Power Factor Correction capacitors provides many benefits, such as:

• Reduced Electric Utility Bills (with typical Payback Periods of Two to Threee (2-3) Years),
• Increased System Capacity,
• Improved Voltage,
• Reduced Heat Losses.

Applications that typically exhibit low Power Factors, which are good candidates for Power Factor Correction, include Air Compressors, Plastic Extruders, Machining Tools, Stamping Equipment, Pumps, Blowers, and other similar devices.

Q: How do we undertake Savings Vertifications in Facilities that have more than one production line?

A: When we plan a Measurement and Verification Process, we take into consideration predictability, measureability, and the likely impact of all plausible factors, including (but not limited to) plant throughput, man hours, machine hours, plant equipment intensity and schedule, occupancy levels, and weather. We correlate the consumption and production data over a few years prior to the installation of the Energy Automation System. In order to determine the savings, it is imperative that we get the various product mixes for each product for as many months as possible, because the longer the period, the more accurate the verification. We have access to software applications that find and define the relationships between a facility's electrical consumption and any of several sets of monthly statistics that indicate a degree of load and usage of the facility. We have experience in undertaking the measurement and verification in plants with a number of product lines, too. It is certain that there is a statistically valid relationship between any manufacturing facility's total production each month and the total electricity consumption. Energy Automation Systems has analyzed this relationship between production and electricity consumption in many facilities and there is always some correlation between the two values.

Q: What is Power Quality and how can it save me money?

A: The elctric utility company or generator system is taksed with supplying the facility with a steady source of elctrical power. This entails a predictable and stable voltage, a predictable and stable frequency, and a dependable and steady source of maximum current. Any deviation from these three targets, at your supply point or inside your facility, is a deviation from the ideal, and this is referred to as a "Power Quality" problem. Of course, the presence of each of these three factors at your supply and inside all points of your electrical system is considered Perfect Power Quality.

Fact: No facility has Perfect Power Quality. In actuality, within today's increasingly complex electrical systems, power quality is an often overlooked and costly element. There is a widely held mtyh that poor power quality has no cost, so long as there are no obvious, clearly seen manifestations, such as tripping breakers, burning of equipment or electronics, or erratic production operations; however, the same variations from Perfect Power Quality that cause these problems in sufficient magnitude also cost money when at smaller, less obvious values, even if there are no overt "problems."

Electronic and Motor Loads are regularly damanged and affected by Poor Power Quality and create the greatest costs. Unwanted variations in voltage or frequency cause cumulative wear in both types of loads. A weak current source starves these loads of power and creates over-hot operation, which leads to premature failure. For instance, computer power supplies should last at least five (5) to ten (10) years before experiencing failure, but do they typically survive that long? Motors are silent witnesses to the cumulative effect of Poor Power Quality, because of their long operating lifetimes. Often times, motors are simply replaced or repaired as they fail without the cause of the failure being diagnosed. Poor Power Quality issues can cut motor lifetimes in half, or worse. Would you not like to double the operating life of your motors?

Q: What is a Project Design and what does it do for me?

A: Correcting the Power Quality Issues in a specific facility is not as easy as swapping out lightbulbs or replacing a few motors. Each of these steps only requires very simple information that can be gotten from the equipment's nameplate data, which is why the companies that sell these products an perform the initial design work at no charge to the customer. It's really easy to do, and the lights and motors recommended will be selected from a number of stock, off-the-shelf products that are maintained in inventory by the supplier. The only purpose of the initial "design" work is to permit the vendor to know which models and what quantities of these products will be needed in that job.

Sadly, our life is not that simple. First, we do not have "off-the-shelf" products, because everything we specify into a job is custom-made for not only that job, but for that specific piece of equipment or that exact point in the electrical system that it is intended to be placed at. Secondly, we cannot even have a "standard" approach to our work because every single facility is sufficiently different to make this cookie-cutter approach impossible for us. IN fact, we cannot even successfully do our job based upon examining even detailed plans of a facility's electrical system. Our design work must be based upon observed and measured data from, literally, every single electrical load and circuit in your entire facility. All of your equipment and each of your electrical circuits forms a highly interactive whole that ultimately connects to your building's electricity meter. It is only be thoughtful and detailed evaluation of each seperate element in this overall system that we can responsibly arrive at the most cost effective set of treatment recommendations for your facility.

Q: What should I pay RSE for this "Project Design" work?

A: About Twenty Percent (20%) to Thirty Percent (30%) of our project design effort is invested on-site, inside your facility, with our technicians gathering the data and performing the testing required to fully model your operating electrical system, then, once this information has been gathered and turned into a complete site report, it is forwarded to RSE’s Technical Staff for further analysis. This is when the real work is done.

RSE's experienced staff applies sophisticated statistical modeling and prediction techniques to every load and circuit within your facility with one goal, the reduction of Reactive and Harmonic Current, along with Kilowatt Power Consumption demanded by your building's operation. RSE's satff applies the financial criteria you provide to making the load-by-load and circuit-by-circuit decisions about possible electrical treatments, then, each posisble treatment is adjusted to exactly match your system's unique electrical requirements. The total package of recommended treatments, also known as the "Project," is aggregated into one simple to understand financial project, for your consideration and approval.

This process, for very small businesses, can be accomplished in only a few dozen hours. With larger business, the investment can easily become hundreds or even thousands of hours of work. Despite the small charge we impose for this project design work, we rarely, if every fully, cover our own back-end costs on these custom designed jobs. Instead, we depend upon our proven methods to generate a project that exceeds your investment targets, and aim for creating a reasonable profit margin on them, while performaing a complete project installation for you.

To us, the result of all this work is useless information. It only has value to you, as a blueprint for customizing your own electrical system in to a more efficient and less costly part of your business.

We have yet to find a way to stay in business without charging customers for custom work, have you?

Q: Will RSE's work disrupt my business?

A: We have a handful of rules that have served us and our clients very well over the years. One of these rules is that we do not ever apply any power treatment equipment in series with any environmental or production loads or circuits in a building. We simply do not want to face the liability of causing these loads to stop operating, should any of our equipment malfunction. Also, series applied Power Quality Products are notoriously inefficient, electrically, and generally cost more money to power them than they save on an electricity bill.

Another rules that guides all of our work is the same ash te first promise made by doctosr in their Hippocratic Oath, "Do No Harm." If there is even the slightest risk of introducing a new electrical problem into a client system with a particular treatment, or if our experience does not extend to give us confident solutions for a particular situation, we make the simple decision to not treat that load or circuit. Rarely, with a few exceptions, have we ever chosen to not treat an entire client facility, simply to meet our own standard for utter safety and reliability.

Because of Energy Automation System's uniquely simple approach to electrical treatments, and from the time-honed installation friendliness of all of our custom products, it is a rare instance when your equipment must be off-line for more than a few minutes to complete one of our installations. When a 24-hour 7-day work schedule is in effect, we even arrange for our installations to occur around your already scheduled perventative maintenance shutdowns. Our goal is not to interfere with your business or personnel in the slightest while we perform an installation, or in the years after that installation has been completed.

Q: What degree of Billing Savings can I really expect? 
A: In all actuality, this question really means "How much of a return will I see if I invest in your approach?"

What if we could reduce your electricity bill by Eighty Percent (80%)? Would that not be great? Now, what if it took Twenty-Five (25) Years for this savings amount to reimburse you for the cost of our work? Would that still be a great deal? No way.

What if we could only reduce your electricity bill by Three Percent (3%), but the savings paid for the cost of the work in Six (6) Months? Would that be a good deal? Of course.

Depending upon the conditions of your electrical system, the mix of equipment, lighting, and air conditioning you have, your normal hours of operation, and a variety of Power Quality Issues, wecould see project design results in your facility ranging from Two Percent (2%) to Thirty-Five Percent (35%) Billing Savings, with Payback Periods ranging from Ten (10) Months to over One Hundred (100) Months; however, typically, the range is narrower, with values ranging between Five Percent (5%) to Twenty-Five Percent (25%) with Payback Periods under Thirty-Six (36) Months. Severe Power Quality Issues can lengthen the Payback Period; however, in no instance will we bring you a project that cannot full pay for itself from billing savings on a monthly basis, if the project is financed through a lease or monthly payment contract.

In other words, Return On Investment (ROI), only from direct electricity bill savings, normally ranges from Twenty-Five Percent (25%) to Fifty Percent (50%) APR, which is not a bad investment in today's market, and that is not considering the many other savings you gain, quite apart from the billing reduction.

Q: What are these "Other" Savings you mention?

A: These "Other" Savings that were mentioned include motors, light bulbs, ballasts, transformers, panels, switchgear, breakers, starters, controls, wiring, SCRs, diode arrays, switching transistors, and microprocessors all running cooler. Switching Power Supplies become more stable, process and production controls are more accurate and reliable, air conditioning and refrigeration is more effective and reliable, in-house and outside maintenance and repair labour costs decrease, along with equipment repair and maintenance parts, are all additional benefits as well. Other benefits include light bulb and ballast replacement costs decrease, costs to production or process downtime are decreased, computer data is more secure and safe, comptuer operation is more reliable and stable, communication systems are more reliable and clear of problems, PC screens stop flickering, lights stop flickering, circuit breakers stop tripping, and PLCs and other automated controls stop malfunctioning.

All of these "side benefits" are included with an RSE  installation. How much would this save your company?

Q: Why can't we just do this ourselves?

A: You probably could do a majority of this yourself. With enough study and determination, in time, most skilled electrical engineers could understand most of the techniques we use. In fact, some of our applications look very simple at face value and could be fairly easily copied. The hard part of this work is actually more financial in nature than electrical.

We fully guarantee and provide and insurced savings guarantee for every one of our projects, thus eliminating all financial risk to our clients. Our projects often exceed many hundreds of thousands of dollars, or even several million dollars in overall price and overall projected savings. None of this is a risk to you if we perform the work; however, if you attempt the work internally, all of it is risk.

When an RSE/Energy Automation Systems project is designed today, it is predicated upon the experience of over Seventy Thousand (70,000) successful installations that we have tackled around the globe since 1978. There is no guesswork, no uncertainty, and no risk-taking involved in our design and installation process. None. Also, the majority of our methods that are not commonly understood and are not readily apparent cannot be replicated by even the most talented engineer outisde of our company, and no, we do not hold classes to teach these methods. We have learned these lessons through over three decades of hard won experience.

Finally, we ask the following question: "If your people or present technical advisors could have tackled and arranged a project like this on their own, why haven't they?"

Q: What is this "Treatment Equipment" that RSE will apply in my business, and how does it work?

A: Generally, we install Reactive and Harmonic Current Correction, along with a variety of different voltage control devices, throughout your facility to reduce the total amperage and wattage demanded through your entire electrical distribution system. We decide exactly what equipment to treat, at which locations, and to what values only after we have performed a complete on-site data collection and system mapping effort.

The specifics of our business are just that, our business, and we will not educate others to our methods and systems. Even the approximately three thousand (3,000) field personnel working out of our Five Hundred plus (500+) worldwide field locations are not privy to RSE/Energy Automation System application and system modeling protocols. We very openly discuss the general principles underlying our methods, the general specifications of our products, and the general effects of our work on a client facility's electrical operations; however, in today's highly competitive business landscape, Energy Automation Systems has carved a unique success using our own methods, in our own way, within our own business model, and with today's utility companies looking to move into the end-user services business, no one can be dismissed as a potential competitor.

Do you freely share your most valuable and private processes and methods?

Q: Does a Voltage Imbalance between the phases at the motor affect kWh, kW Demand, and KVA Charges from the Utility Company?

A: Yes, though it is mainly in three phase motors. A phase imbalance increases the losses at the motor and causes motors to consume out of balance current, thus leading to increased internal losses and temperature; therefore, if the voltage imbalance is at the motor, it may have problems and will consume additional kWh.


Q: Does a substantial Current Imbalance between phases at the meter affect metered kWh from the Utility Company?

A: No, it does not.

Q: What are harmonics?

A: By definition, "Harmonics" are any interger multiple of a fundamental frequency. Most electronic equipment generates harmonics, and we treat them by using harmonic filters that reduce the harmonic current drawn by these loads, thus reducing the distribution losses. These reduced distribution losses are our savings. We use two types of harmonic filters, active and passive.

Harmonics are related to periodic waveform patterns. The power you get from the Utility Company is Alternating Current (AC), and in the United States, that current operates at a frequency of Sixty (60) Hertz (Hz), or cycles per second; therefore, it is a periodic function of time. If we apply this definition, harmonic currents would be any multiple of 60 Hz, such as 120 Hz (the Second Harmonic), 240 Hz (the Fourth Harmonic), 300 Hz (the Fifth Harmonic), etc. There are certain loads that, due to their operating characteristics, draw current with a frequency higher than the 60 Hz provided by the Utility Company. One example of such a load is the Personal Computer (PC), and other examples include Variable Speed Drives, DC Motors, and Welders, only to name a few. In the conversion of AC to Direct Current (DC) inside your PC's Power Supply, harmonic currents occur. If you were in a building with several hundred computers, for example a Publishing Office or a Casino with electronic slot machines, the distriubtion panels would have to be oversized in order to handle the large amount of harmonic currents, due to the increased heating losses compared to just the 60 Hz current. To treat these loads, you need to use passilve filters such as the PowerLiner for three phase loads, or third order harmonic filters for single phase loads, such as computers or slot machines. Active Filters can be used, but due to their high cost, the loads need to be conveniently grouped in order to maximize its application.

Q: If one works well, will two work better?

A: Normally, the question is worded more like one of the EasiLiner questions above, "If one EasiLiner can save ten percent (10%) on a motor, will two EasiLiners save twenty percent (20%)?"

The answer to this question is absolutely not! All EASI products are designed to optimally adjust savings in one single treatment and adding further treatment of the same device will usually worsen the problem instead of correcting it.

Some technologies can be successfully combined to create additional savings; however, the combination of these technologies may increase the payback period to an unacceptable time frame, so it often left up to the decision of the Client if they will be used. Generally, FrigiTech with the Final Condenser is combined, but remember that twice the FrigiTech does not mean twice the savings.

Q: Will EASI's equipment harm our equipment?

A: Have you ever been asked this question by a customer? If you have not, it is only a matter of time, because they will. The short answer, of course, is "No." There are many articles on the benfits of using our products spread throughout EasiWorld, providing all the detailed information you will need to justify your "No" to the customer. Additional information can be found in Chapter Five (5) of the Dealer Manual.

Q: What financial help can I get from the Small Business Administration?

A: The Small Business Administration (SBA) generally works through approved banks and have pretty significant paperwork requirements that start with a business plan. If you go that route, or any financing route for that matter, the business plan is extremely important. The good news about the SBA is that they have the money to loan. The bad news is that they are the government, and react very slowly. I would look at them, but I would also try and find money through banks, credit unions, or even a private lender, too. This article here is a good starting point.

One segment in this explanation specifes type and size restrictions. Size is not a concern typically; however, types are limited as follows:

Types Of Businesses Eligible:

The vast majority of businesses are eligible four financial assistance from the SBA. However, applicant businesses must operate for profit; be engaged in, or proposed to do business in, the United States or its possessions; have reasonable owner equity to invest; and, use alternative financial resources first including personal assets. It should be noted that some businesses are ineligible for finacial assistance.

I would contact your local SBA office and just start there. They offer assistance in many ways, including retired professionals, who can help you set up your business.
