How To Power Appliances From A Generator
Distributing electricity safely is a complicated process. Columbia Water & Light has a detailed process for delivering electricity so it does not surge or back feed into the system. After purchasing a generator, you will need to determine how the electricity will be distributed to the electrical equipment in your home. Without proper transfer switches, equipment can be damaged and people can be injured.
- Plug the appliances directly into the generator. The most straight forward approach to using a generator is to unplug the appliance and then plug it into a power cord that runs to the generator outside. This method makes it easier to control overloading the generator and is the method most suggested by Columbia Water & Light.
- Hook the generator into the electric panel. Hooking a generator into your home’s wiring system is not a do-it-yourself project. It requires a certified electrician and a transfer switch. Your electrician will need to apply for a permit from the opens in a new windowCity of Columbia’s Building and Site Development office in the Community Development Department. The electrician will need to install the manual transfer switch between the house breaker and the electric supply. This will require coordination with Columbia Water & Light to get your electric service disconnected while the transfer switch is being installed.
WARNING! If you try to hook the generator into your house’s wiring system without disconnecting from the utility’s supply, there could be disastrous results. You could permanently damage your generator and the electrical appliances in your house. The generator could also back feed electricity into Columbia’s electric system. This could mean injury or death for the utility’s staff repairing service on a line they didn’t know was energized.
