Why not use AFCI's in RVs?

has any one read the new construction code.
in arizona, they are talking about r49 insulation for attics.
the only way to achieve thar is with 24 inches of foam.
the new codes were written by construction companies, and suppliers.
its the retail customer, as usual, that gets the shaft.
with an approved shaft of course. it will show up on the bill.
probably under special services.

Not to mention, to the best of my knowledge, RVs aren't bound by the NEC code.

They most certainly are, as stated in 90.2(A)(1).

I realize that applicable ordinances, not the NEC, does the binding, but NEC itself says it applies just as much to RVs as to anything else. Article 551 is additional info specifically for RVs, on top of everything else.

IMPORTANT "realization"!..;)

*NOT* "bound" by NEC - *UNLESS* the code is adopted by the/a jurisdiction by local ordinance - at which time it becomes the applicable code for that jurisdiction.

Same for the UBC, UFC, etc.
Regular procedure in the city where I worked to either continue with the existing (already adopted) codes -or- make whatever modifications to the new code/s when a newer one was issued.
The newer edition then was adopted (with our addendums)- and became the new code in force.

It then became the (City or County name) Electrical Code, Building Code, Fire Code, etc.

Some cities - such as Los Angeles, New York, etc. - develop and publish their own codes from "scratch".

I asked the same question HERE back in January. Great minds think alike LOL.

Well kinda. It covers a few very limited points of RV wiring but it's does not make builders follow all the codes that we normally build homes to.

Looks pretty detailed to me, here it is...give it a read and tell me what they missed. http://www.freenec.com/T451.html

I know an electrican that removes them as soon as the house passes final inspection.I really think there is much ado about nothing. In a modern home there are plenty of outlets and no need for an extension cord. That is what they (code writers) thought of originly. Where cords were getting overloaded and melting. Yeah a nail or staple might get thru a wire but that doesn't happen that often. I remebember the orignal GFCIs outlets. They were NO good. And no one wanted to spend the money for the breakers. I like them, I think they have saved a LOT of lives. I don't see that with AFCI

I have a small side line business that rehabs and flips run down properties a few times a year (low income families gets a much nicer home at a much lower cost than they would be able to afford normally). Have never run across that requirement in the building codes and have never seen one of those breakers before in the 10 years I've supported this.

The NEC Article 551 covers RVS.

Why would you want something that is so problematic? I have heard lots of complaints from people that have them in their stick built. It seems that vacuuming the bedroom carpet is nearly impossible as the static generated will trip the thing continuously.

i have seen people completely empty their panel of these and go back to the old ones, after they tripped out for the 90th time.
