National Electrical Code requires a system in place that prevents an emergency generator from feeding back into the utility line. This interlock will only allow the generator breaker to be switched on if the main breaker is off. Or the main breaker to be turned on if the generator breaker is off.

You will also need:
  • A generator with a 240 volt outlet
  • A double breaker for the generator
  • An inlet box and wiring connected to that double breaker
Using this interlock will allow you to power your existing house wiring with your generator (within its wattage limits), including 220v circuits such as a well pump.
