If the Main Breaker Is off Will the Standby Generator Switch On?
A backup generator for your home can be a lifesaver when storms, fires, or other events cause your electricity to go out. A generator can provide temporary power for your lights, your heating and cooling system, your refrigerator and freezer, and any other devices that you feel you absolutely need during a power outage.
Portable generators, available in various sizes and power outputs, can come in handy if you need power for activities such as camping or tailgating. With these generators, you merely start them up and plug in any devices you need.
If you’re going to use a portable generator at home however, it’s very important for you to know that you should turn off the main breaker in your home’s electrical panel when the generator is running. This will protect the electrical system in your home when the power is restored from the grid. If you fail to turn off the main breaker, you risk damaging the items that are running on power from the generator with a power surge once the power grid is back up. Running a generator when the main breaker is on can even cause a fire once power is restored. You can switch off your main breaker manually, or by the use of a transfer switch.
Automatic Standby Generators
If you have an automatic standby generator, things work a little differently. The automatic standby generator is connected to your home’s electrical system via a transfer switch. When the transfer switch detects that your power has gone out, the electronics in the generator switch it on to restore power in your home.
Once power is restored from the grid, the transfer switch is once more alerted to that fact, and it directs the generator to disengage. After the restoration of power, the generator will continue to run for a minute or two performing a cool down cycle. Once the generator has cooled down sufficiently, the generator will turn itself off to be ready for the next power outage.
