Generator Types
Generators come in 2 types:
- Portable generators – stand alone and are not directly connected to your home’s electrical system.
- Standby or backup generators – connect to your home’s electrical system to provide backup power during an outage.
Generator Safety
Improper generator usage can lead to damage, injury, or death. Always notify Tri-County Electric Cooperative (TCEC) when installing a permanent generator so it can be noted on your account, and always install a double-throw switch. For smaller portable generators, a switch is not necessary.
Transfer Switches are Essential
Any time a generator powers loads through the permanent wiring system of the home, farm, or business, a transfer switch must be used. Adding a standby generator requires a transfer switch, also called a double-throw switch.
- This switch disconnects the electric load from the electric utility grid.
- It prevents the backflow of current into the utility’s lines during an outage.
- It is usually located between the utility meter and the loads to be served.
- It is a requirement of the National Electrical Code (see NEC Article 702.6).
- It prevents damage to the generator when service has been restored.
Portable Generators Tips
Set-Up
- Nothing should be plugged into the generator when you turn it on. This prevents a surge from damaging your generator and appliances.
- Do not plug directly into a home outlet or electrical system.
- Use an extension cord to plug appliances into an outlet on the generator.
Enclosed Spaces
- Never operate a generator in an enclosed area, such as a garage or basement.
- Generators produce gases, including deadly carbon monoxide. They require proper ventilation.
Wet Conditions
- Use caution when operating in wet conditions.
- Ensure your hands are dry before touching the generator.
- Protect the generator by operating it under an open, canopy-like structure on a dry surface.
Fueling
- When you refuel the generator, make sure the engine is cool to prevent a fire, should the tank overflow.
- Never store fuel near the generator, unless a proper container or fuel tank is used.
