Interlock on Service Panel
mefly2, Walt does mention after an electrician modifies the panel so I’m guessing he’s talking about an Interlock that prevents one from sending the generator current back on the grid but your point is valid.
We had our service panel upgraded and had the electrician install such a device. You have turn off the main breaker, disconnecting your panel from the grid before you can turn on a 30A breaker wired to the outside generator receptacle.
Works great and allows us to connect our Champion 3400 Dual-Fuel generator to the house if needed.
BTW, another benefit of the Interlock vs. a transfer switch is you can pick and choose which circuits you want to run off the generator compared to ones that are dedicated/hardwired to a transfer switch.
