Can you run a generator to a sub panel?

It is not physically possible for the MAIN and the Generator to both be turned on at the same time. The only way you could have it go into the sub-panel would be if the sub-panel was interlocked to disconnect from the main panel, so you absolutely cannot feed the main from the sub, no way, no how.

You typically will need to turn the circuit breaker off and turn the fuel valve on before starting it up. Give the machine a few minutes to warm up, then flip the circuit breaker on. Use long, heavy-duty extension cords made for outdoor use to connect appliances to the generator one by one so as not to overload it.

Which is better transfer switch or interlock?



Compared to a transfer switch, which is limited to a particular number of circuits, an interlock kit allows you to run power from a generator to any circuit within the electrical panel. While this is good in theory, there’s a risk of overloading the generator if it’s not sized according to the load.

How do I choose a transfer switch?
