When you have the boiler/furnace powered by the
generator all of those upstream safety devices are
rendered inoperative, true they are not required in
every jurisdiction, but up here in the northern cold
parts they are...

You make a good point, but . . . . That would depend on where the cord
is mounted. They could well be downstream of the receptacle too.
