Raceway requirements on buildings near an Ocean(Rigid,EMT,PVC Sch. 80?)

[Lopez12Oscar]

Need some help. Before a project was started my manager had mentioned we have to install Rigid pipe for a solar and battery storage install only because we are hundreds of feet near ocean water. I have searched and googled throughout the codebook and I cant seem to find anything with this particular install. The project is in Crockett, CA. Anything helps thank you.

It is probably a local rule. I know that I had to use rigid pipe for a temp pole we installed at the NC coast. The power company wouldn't hook it up otherwise. Btw, welcome to the forum

Crockett is not on the ocean.

Also last job I did there no such rule was enforced by the county. We did paint the exterior EMT, fwiw.

Pretty sure neither the county or Crockett have their own electrical code on this. I believe there's a general code rule for materials to be appropriate for the environment, that's all I can think of.

Being near the ocean can make just about anything corrode. Even zinc coated rigid will corrode. The easiest solution is to just paint it periodically.

I'd opt for PVC, sched 80 if physical damage protection is required. Of course, that's if there are no local rules prohibiting PVC for this application.

Me too, it's not going to rust.

Every outdoor installation I have seen that used PVC of any kind ends up with horizontal runs sagging. So I'm not a big fan of using PVC outside. Great for underground. Or if you don't care if it sags a little.

Depends on how you support it. There is also PVC coated RMC (Robroy) but I hated installing it for a number of reasons.

Being near the ocean ...

How near? Crockett is on an estuary about 20 miles from the ocean per se. Actually it's an interesting case because depending on which side of town the nearby water is considered either a bay or a river delta. Not that the water cares what we call it, but if one had to go toe-to-toe regarding a product warranty that mentioned 'saltwater' that could get quite interesting.

other than the cost of Robroy, I don't care much since I do not have to do the installation.
