Generator FAQ's
by Generac Portable Products

Q: What is the decibel level of Generac portable generators?
A: Because there is no industry standard on how to rate generators, Generac Portable Products does not offer any decibel level ratings. If you demand a quiet running generator, the Generac OHVI powered generator with an extra large muffler is as quiet as any equivalent sized generator in the market.

Q: What does Automatic Voltage Regulation (AVR) do for me?
A: AVR maintains steady voltage. This is important for running sensitive electronics such as, computers, microwaves and televisions.

Q: Can I vent exhaust out of an enclosed area.
A: NO. Carbon monoxide gases produced by the engine can be deadly. Generac Portable Products are designed to be run outside where there is plenty of ventilation. Never run these units inside a home or enclosed area.

Q: Can I connect my Generac generator directly to my home?
A: To connect your generator to your home, use the Generac Power Transfer System. This system is the quick and convenient way to safely use your generator as a backup power system. All electrical connections must be made by a licensed electrician and made to meet local and national codes.

Q: Are larger mufflers available?
A: No. Generac Portable Products has not approved any after market mufflers. A muffler that has not been tested could actually increase the exhaust temperature causing engine damage, possibly voiding the warranty.

Q: Where is the Generac engine made?
A: Generac engines are made by Generac Power Systems in Whitewater, Wisconsin. Generac engines were designed specifically for generators to produce ultra quiet, longer lasting performance. Generac engines run 3-5 times longer than SV/OHV lawnmower style engines, run 30-50 degrees cooler, are 25% more fuel-efficient and reduce oil consumption by 25%.

Q: Which generator should I buy?
A: There is no simple answer to that question. Generators come in several different sizes and styles. The key to choosing the right one lies in determining how you will use it and how much power you will need from it.

Q: What size generator do I need to run electric items in my house during a power outage?
A: Most average homes of 1200 to 3000 sq. ft. can use a 3000, 4000, or 5000 watt generator. The most common items that need emergency power during a blackout would be the furnace blower motor, refrigerator, freezer, lights, TV, sump pump, and water pumps.

Q: How do you determine the wattage requirements of a specific tool or appliance?
A: Electrical items generally state the related amperage (and sometimes wattage) on the data plate. If amps are shown, simply multiply amps times volts to get wattage. Example: A circular saw shows on its nameplate that it requires 9 amps at 120 volts. by multiplying 9 amps by 120 volts you discover that this saw requires 1080 watts for normal operation.

Q: What's the difference between rated and maximum watts?
A: The rated watts of a generator is the amount of power the unit can produce continuously, while the maximum wattage is the power that the generator can produce for short periods of time. Motor starting is a good example.

Q: Does motor starting require different wattage?
A: Induction motors require larger amounts of electricity for initial start-up than when they are running. Some appliances and tools, such as your refrigerator/freezer, furnace fan, air conditioner, electric chain saw, weed trimmer, etc. may require more watts than normal running wattage for motor starting. This must be considered when sizing a generator to meet your needs.

Q: What do you mean by "full capacity outlets"?
A: A full capacity outlet allows the full rated power of the unit to be drawn from a single outlet. On a 4000 watt generator, you could pull all 4000 watts from a single outlet if necessary.

Q: What is a spark arrest muffler?
A: A spark arrest muffler is a muffler that has a spark inhibiting screen attached to it to prevent fires. Spark arrest mufflers are required for generator operation in national parks and campgrounds.

Q: How are the generators protected from overload?
A: All generators feature AC circuit breakers. In the even the unit is overloaded, the circuit breaker will pop out. If this happens, the operator needs to correct the overload condition and then reset the circuit breaker by pressing it back in again.

Q: How do I start it and how do I hook it up?
A: Recoil models start just like a lawn mower, with the pull of a rope. Electric start models connect to a battery and start by pressing a switch. Most tools or appliances can be directly plugged into the unit for operation. To wire your generator to your home's electrical system, the safest and most convenient way is to use a Generac Power Transfer Switch.

Q: Can the generator be used during inclement weather?
A: Generators obviously are used in a wide variety of weather conditions, but they should be protected from the elements to prevent shorting and rusting. Protection for the unit must be provided in a manner that does not impede the air flow to the unit needed for cooling both the engine and generator head.

Q: Can I run the generator inside my home?
A: NO! A generator has an internal combustion engine and uses gas and oil. The exhaust from running the generator contains lethal carbon monoxide. Therefore, this unit should always be placed in a well ventilated area.

Q: Where do I go for parts and service?
A: A listing of authorized parts and service outlets is available for each unit. There are approximately 3000 locations throughout North America. Our toll-free service locator number is 1-877-544-0982. Remember that Generac warranties the generator and the engine manufacturer warranties the engine.
