Transfer switch

It is what allows 2 different AC power sources to be wired to power your RV.

Shore power has failed and transfer switch is swapped to generator side. That is why you get AC power with generator running.

It is a metal electrical box with 2 sets of wires going in (1 from shore power cord/1 from generator output) and 1 set of wires coming out (going to main AC Panel).

It could be behind a panel......need to trace power cord to locate.
Could be burnt/loose wiring or bad relays/contacts
