I'm working in a remodeling , the house is next to the beach and I found that everything is EMT and THHN , is there any reason in the code to use EMT with THHN for a beach house , or I can simply use NM ?
thank you very much

It depends on the local rules. The nec doesn't care which one you use but the local ordinance may.
 
how do I find out?

how do I find out?

If I want to find this out, where should I go ? do I need to talk to the inspector? or who can tell me the local regulations?? thanks

Simple answer is talk to the Authority Having Jurisdiction, AHJ. But if you tell us your location, odds are someone here can advise you.

Just call the inspector in the morning and ask him what you need to know.
 
Ronald, when I first got to Florida I noticed a lot of stuff in pipe that I never saw in New York. I couldn't figure it out. Then I basically discovered for some odd reason people like to use pipe on everything. I don't do a lot of resi, but on all my commercial stuff I use MC as much as possible, and the resi I've done has not been piped, NM or MC. This is in Broward Co. though.
 
I know , my experience is also in commercial , but , I'm starting residential.
my doubt about this EMT being use in a house close to the beach , is because of the moisture , or the wet weather, and thats why they used EMT and THHN in all the house.
I'm gonna have to call the AHJ tomorrow morning
 
We just finished working on a condo down on Deerfield Beach.
It had been wired 20 odd years ago with EMT.
The first time I poked my head up in the attic, I was dumfounded to see THHN laying all over the ceiling and hanging from the joists.
Due to the salt air circulating through the attic, the EMT had turned to dust and some junction boxes were rotted beyond recognition.
I would vote for as much nonmetallic material as you could fit in that place.

I totally agree, I work on a lot of stuff close to the beach. I don't think EMT would be good. I would also vote on as much plastic or NM material as possible. the salt just in the air around the beach will rot everything.
 
I would NOT recomment using any metal conduit system anywhere near a salt-water beach. We use PVC conduit, or NM cabling in such areas. As much plastic boxes as you can get.

I have never understood the uses of metal and electricity since the invention of the plastic box. :roll: :grin: Let alone in salt environment. And yes I have wired a many a beach house here in NC. If the rough-in lasted too long we would have to remove the panel busses to clean the salt build up from them.
