Let me start this out by saying I am the title. 12 volt? No problem, but 120 AC? Anything beside very, very basic confuses me.

So here's my problem. The backsplash behind our stove (typical 26' GMC floorplan) was rotted. I decided to replace it with a nice piece of aluminum diamond plate. Got everything down and took out the outlet that is to the left of the sink. Hmm... three hots, three negatives, three grounds. Labeled my wires. Finished disassembly and then began reassembly.

After much irritation I reinsulated (tell me that the original insulation looks the way it does because of 40 years of wear and tear and not some stoned h.s. drop out that GM hired to pretend the foam insulating gun was his six shooter while he sprayed it randomly around?), got the diamond plate slid in, riveted it back to get the correct curve, put back the overhead wire runner and window trim.

Now the electrical. I had precut the diamond plate for the box and it was perfect. Forced the wires through with liberal use of words my kids aren't allowed to hear, and thought I hooked it up as per my labels. Test... Nothing. No 120 AC in the whole coach. Checked it was plugged in, checked that I flipped the breakers the right way, checked that I had hooked it up. Nothing.

Is there a specific order to the wires that I missed? I'm using a 20 amp capable outlet and hooking two hots to the brass top screw, one hot to the brass bottom screw and the corresponding negatives in the same spots on the other side. The grounds are twisted up tight and one is attached to the ground screw.

Does it matter if I have the hot/negative from the box on the top screws? Do two sets need to be on the top or the bottom? I really am an electrical idiot and despite several google searches can't seem to find a wiring diagram that discusses this problem.

I did see an interesting diagram that put all three hots into a wire nut with one wire coming out to the plug, all three negatives into a wire nut with one wire coming out to the plug, and all three grounds in one nut coming out to the plug. I've never seen anything wired that way before. Is that the answer?

When Johnny says to try each black to each white he DOES NOT mean to touch each black to each white, he means to put your meter leads to each set of black and white wires.

Also check from each black to each green. If you've lost the grounded conductor (neutral) you won't have any power either.

Once you get it going again, take it out and put a ground fault receptacle in.
Seeing as how you have aluminum plate, electricity and water all within reach, it's something you should do.

I am guessing something found a short circuit and tripped the breaker that feeds your shore power outlet. That's the only way that everything in the RV would be dead. You seemed to say you checked everything in the RV, but did you check the breaker that feeds what you are using for a shore power outlet? When you where forcing the wires through the diamond plate, did you scrape any insulation off any of the black wires? Scraping insulation off a white wire would create a hazard, but wouldn't trip a breaker.
