What are the industry wiring standards?

Am wondering if there are RIVA or CSA or some other standards for wiring in a trailer?

I was doing some mods inside the pass-through area and discovered that all the wiring from the tongue area that goes up and into our trailer passes through a hole in aluminum framing and there is no bushing. They seemed to just whack a hole through the body and not even smooth the rough edges off in whatever they went through. Over time this could lead to a short circuit.

Our trailer is only a few months old and I'd like to be able to say to the dealer that it doesn't meet a particular standard. It would be a major job to fix this and I'm not sure the dealer or manufacturer would want to fix this unless it's mandatory?

Besides the wiring question, the aluminum framing member has lost about 1/2 of it's cross-section and the strength is compromised.

You can buy the National Fire Protection Association Standards for RVs, it's only $40 or so.
NFPA 1192: Standard on Recreational Vehicles

Or buy some plastic wire loom like this and slip it on any wires you think are in need of protection.

Also make sure you let the manufacturer know your feelings, send photos and let them know you won't be a repeat customer.

Thanks! I would put a wiring loom on or grommets or some kind of physical protection but the wires are crammed in there too tight. Can't even pull back a bit to put some tape on.

You could use expanding foam in the frame holes to immobilize the wires from chafing.

That's not a bad idea. I was kind of hoping that someone might be able to point me to a code/standard clause 1234, sub-section 5678, para. (ii) that says how this should be done. It's awfully sloppy workmanship at the factory.

I was reading an RV mag article the other day that talked about RVs that are imported to Canada and don't have the required certification. The RV has to be thoroughly checked over and one of the things they look for is wiring that passes through metal and doesn't have grommets. So there must be a standard somewhere, at least in Canada.

I think what you found is pretty standard. I have the same issue except my wires are running through torch cut steel holes unprotected. Totally irresponsible practices. At least in a house your wires rarely move. In a TT they are constantly being jiggled about. I'm going to try slipping a sleeve over my wire. I can't reach the areas and cannot see other areas where more may be lurking.
