Standby Generator FAQ
What is an automatic standby generator?
An automatic standby generator is a back-up electrical system that operates whether you are home or away. Within seconds of an outage, it automatically supplies power directly to your home’s electrical circuit breaker box. After utility power returns, the generator shuts itself off and waits for the next outage. It operates on natural gas, diesel, or liquid propane gas and sits outside just like a central air conditioning unit.
Why should I buy a home standby generator instead of a portable generator?
While portable generators are effective in terms of backup power, a home standby generator produces more power, offers hassle-free, automatic operation even when you aren’t at home and exercises weekly to ensure extended life. With a home standby generator, there is no need to run extension cords, the unit will operate rain or shine, and it will automatically turn on even when you are not home.
What is the difference between an automatic air-cooled generator and an automatic liquid-cooled generator?
The engines! Air cooled generators come with engines that use fans to force air across the engine for cooling, while liquid cooled generators use enclosed radiator systems for cooling, similar to an automobile. Generally, liquid cooled engines are used on larger wattage generators due to the larger engines required for the higher power output.
Can an automatic standby generator replace utility service?
No. The generator fuel costs would be much more expensive than buying power from the utility company since their cost to produce electricity is divided among thousands of customers.
How do I correctly size a generator for my home?
The most logical way to determine your needs is to envision your home without power! Some outages may be short in duration, while others could last for days or weeks. What would you like your living conditions to be? In a typical installation with an 8 kW, eight circuit generator, you could connect (1) lights and TV in the family room, (2) microwave and lights in the kitchen, (3) refrigerator, (4) power to the bathroom, (5) computer and home office, (6) garage door opener, (7) air conditioner, and (8) furnace.
Can I install the standby generator myself?
You could perform the simpler site preparation steps and have a professional make the electrical panel and fuel connections, or you could complete the entire installation yourself. However, for safety reasons and to ensure adherence to all local, state and national electrical codes, particularly for non pre-wired or larger systems, we recommend you use a licensed contractor.
Do they have to be maintained?
Yes, simple maintenance is required. All generators require periodic oil and filter changes to ensure maximum performance for years of reliable service. Preventative maintenance kits are available Refer to the owner’s manual for routine maintenance procedures and schedules.
What type of oil should I use?
An SAE rated high detergent oil that meets API Service Class SF requirements for gasoline engines, similar to your car. A 10w30 oil is recommended as the standard generator motor oil to use in our home standby generator engines. Regularly check the oil level in your standby generator. Refer to your owner’s manual for details.
What happens if the generator gets over loaded?
In the rare event of an overload, the generator’s circuit breaker will trip, disconnecting the unit from the load. Simply correct the overload and reset the breaker in the generator.
