Code & safety requirements

I just scanned through the NEC article 551 that specifically covers RVs. Seems to cover pretty much anything electrical to do with an RV.

My question is, is this for manufacturers only? What happens if an RV owner does substantial modifications to the electrical system and/or components. Is he/she supposed to do any work in accordance with the NEC and should they be taking out a permit? What would happen if the modifications were improperly done and there was an electrocution or fire?

I've read many times about owners doing modifications themselves like upgrading their panel from 30 to 50 amps for example. If it were a house, you'd be required to obtain a permit and have it inspected.

Same goes for work on the LP system and appliances. Is there a Gas Code that is similar in it's requirements? What if someone does extensive changes to the LP installation?

Is there a correct procedure that you should be following to have your work inspected and approved or is this something that just falls through the cracks?

Are RV techs specifically trained and licensed to do electrical and LP work?

    Is this for a new unit or is the original certification only good for a certain number of years like on say, propane tanks?

    If somebody modified something though, how would anyone know? I can see somebody buying a pre-owned RV that's been altered and having no idea it has. You can go to any place that sells RV parts and they will sell you LP fittings or a new furnace or water heater with no questions asked.
  • Since you brought it up...you can pretty well be assured if you modify your rig and there's an electrocution or fire, they will be looking it over with a fine tooth comb for anything not done properly. If it can be shown you knew or should have known it was not done properly you'll probably be hung out to dry. If it was deemed negligence on your part, you'd be out of luck for sure...

  • Thanks for that!

    I'm an engineer by training and worked in the construction field a long time. I'm so used to building construction being highly regulated and inspected for compliance and the consequences if it's done wrong. I just have to wonder about some of the things owners do with their RVs in comparison to what you can and can't do in a house from a safety point of view.

    But then, you can totally rebuild and restore an old car and then just get it licensed when done.
  • First, the NEC is a collection of standardized rules. There is no law that says a gov't entity, ie. State, County, Municipality HAS to adhere to these standards. I believe almost all do. Permitting is also under the purveyance of your Gov't entities and I don't think you'll find any that will issue a permit for a moving vehicle. In most locales, a property owner is allowed to work on their residential electrical service without a permit.

    LP gas for RV's is regulated by federal DOT and most mfg's will adhere to the RVIA and national Fire Safety standards. Again, this is not a building so no permitting is needed.

    There is no procedure for an owner of an RV to work on his rig. You can make it into a spaceship if you so desire. No permitting or restrictions on who can do the work if you have it hired out, no licensing or certification is required.

    As RV's become more sophisticated, there is probably a push to have trained technicians that have completed certain course work or are able to obtain an endorsement. Who that endorsing body is, I have no clue.

    FWIW, I've worked in building trades since I was a wee lad and am presently a Residential Building Contractor. Because of the nature of what I do, it's necessary for me to keep up on ordinance, code changes, permitting, inspecting, new technologies, and a host of other legal matters. I think folks put too much importance into building inspection, feeling that once inspected, they are immune to any calamity and disaster. The role of a building inspector is to insure that the codes adopted for the agency they represent are adhered to, safe buildings being the result. There is no guarantee that the wooden stair tread in your stairwell won't splinter and your foot go right through it, for example.

    If you're not conversant with safety standards, don't have the skills or knowledge, or just don't want to complete projects, the best you can do is hire service and repairs done through a reputable service shop.
