Romex ok behind

Hi Folks,

I will be running a 2 or 3 new dedicated 20 amp circuits. One for microwave. All 12 gauge. My plan was run wire individual wire in flex cable. The guy, a pro, for better or worse, said oh he will do it but romex is all I will need since non of it will be exposed as it is going behind everything the whole way, that is twin bed etc.

Any thoughts on which way I should go. Is it worth the extra time and money to go with the flex?

Thanks you

FWIW, everything in our 1997 is Romex. Also, as I have been taking the 1970 apart, it is Romex as well. There are grommets where it passes through metal holes, but that is the only protection.

If it is behind wall, no problem. If it is behind furnishing but in front of walls you need to consider if things stowed in the area could be a problem from repeatedly hitting it. I would probaqbly go with the romex unless it looked likely to be abused

one suggestion or heads up

I wouldn't use the push in method of attaching the wire to the receptacle. I had issues with that, even in my house, and RVs bounce around. So use the screws, and electrical tape them afterwards. Sorry if this goes without saying.

Re: '71 Tradewind Dinette


When it come to electrical and me and many others nothing goes without saying.

Thanks for the responses

It won't be behind the wall. I just don't want it to look thrown together with yellow Romex. I have been too careful with this reno/resto to have the topside things belie all the work into the frame, tanks and all the rest getting to this point. That nice dark grey flex looks good just more work and money. I have the romex. I also have the flex. The 12 gauge wire around here is 18cents a foot times 3 times 3 runs. small potatoes, perhaps, but after all new appliances, Por 15, marine plywood and all the rest, it starts to hurt. Heck yesterday I bought 3 boxes of stainless steel screws of various sizes and dropped $35 and the day got way more expensive from there.

I remember when I asked in a post. "why does a resto add up so fast" I was told why?

Anyway as far as Romex or not it sounds like either way if I am not abusing it.

Where there is no vibration, romex,solid core ok. Trailers do vibrate.

I recently installed a new AC. Stranded the while way.

It costs a bit more, yes...

So, if you plan to keep AS " forever" the cost will be reasonable.

If you can re-run in the conduit should a problem arise, run romex.
Peace and Blessings..

IMHO I would use only stranded wire in anything that moves. That includes, RVs, autos, boats and aircraft. ROMEX is great for houses and homes or anything that does not move. Vibrations cause problems. You know that saying- -pay me now or pay me later.
BTW: One summer 45 years ago I had a 10-week work/study intern job at the Rome Cable Corporation where ROMEX and hundreds of other types of wire and cable were manufactured. It was quite and education. Residential and commercial ROMEX cable was being fabricated and packaged on automated assembly lines running 24/7. Very little human interaction required, besides feeding the machines wire and plastic, and periodic QA tests.
I would never recommend ROMEX in an RV.

I suppose after reading Stanley's comment, you will sleep a lot better if you use stranded wire in your baby- especially if you have done everything else the best (and most expensive) way you know how. I know I would have been all set to go with regular romex until he chimed in. You had to ask, didn't you.

If I understand the question, it's to use individual wires in a flex cover or just use exposed romex. The only thing I would say, don't use anything unless it's inside of something, a wall or a tube, since it doesn't take much to cut the cover.

I would route it inside flex tube, romex or individual strands.

Thanks all.

I will go with the flex. It was the well recommended guy I am hiring that chimed in that everything uses romex.

It doesn't probably surprise any of us here.
