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 located at the top of the left side breaker column of your electrical panel box
  • 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 220 volt circuits such as a well pump.  This interlock is not listed. It does meet the requirements of Article 702 of the National Electrical Code ANSI/NFPA 70.
