GFI Circuit Plug
I have a 2011 Infinity 5th Wheel and the dealer tells me I have a bad GFI plug (master) they have ordered one, but it has been over a week and still not received. Why couldn't I use one from Home Dep...

And whatever you do, observe line and load markings on the outlet. I've seen too many do it yourownself'ers get the wires mixed up and the new ones won't work if wired improperly.
And of course there are plenty of you out there that should not do ANY electrical work.
It isn't just DYIers that get it wrong. CR wired my GFI backwards. I installed the new residential GFI exactly as CR had the original wired and it wouldn't power up. Turns out the reset button will not work on the residential GFI if the unit is wired backwards, but the original GFI would. Guess the original unit had a mechanical only reset button vs mechanical/electrical. I used a voltmeter to verify which lead was power and which went to the downstream outlets. Reversed the wiring and finally everything works as it should.
Another word of caution, when my GFI failed, it almost started a fire. It didn't fail electrically, instead, the push-in connection developed too much contact resistance, overheated and melted the plastic housing. Then because these units are mounted with an extension box, the hot plastic/metal was very close to the plywood wall board and blackened it. At least the GFI did eventually trip and prevent a fire.
