OK, I think I am 99.9% right on this but would like to see if I have missed something. This is a friendly disagreement between my boss and my self.
Generators installed out doors. The gen. sets came with a factory installed GFCI recp. for the block heater and battery charger. The box and GFCI are installed inside the gen. housing. Now after a few year the GFCI's are going bad, Will not test with the button, trip out even with no load etc.. He says that we should replace with a standard recp. because there is something in code ( cant find it just now) that allows us to do that because the gen. sets are under supervised control. I say no. My argument to him is 1 code doesn't allow for this. 2 even if it is under supervised control that doesn't mean just because you have a key to the housing you couldn't get a hit if the heater shorted out and didn't trip the breaker. 3 the factory didn't install the "best" grade GFCI recp. to begin with so its time for them to fail.
I am trying to make him see that we should replace them with the GFCIs that are WP and of a commercial grade or just install GFCI breakers on the line that feeds the recp. That way we know they are not wet from blowing rain or dust and dirt. And they are not subject to the vibration when the gen.sets are running. Am I wrong?
