NEC Code

What type of service riser can be used if the service drop is not using the riser for support? It's point of attachment is an eyebolt. Main service size is 100A, single phase, 3-wire. Riser would come out of the panel 6', sweep 45 degrees to the left and go another 10'. It does not go through the roof and it would be fastened to the building every 24". Service conductors are #4 copper. Can I use PVC instead of IMC or rigid?

Speedy Petey

PVC, IMC, EMT, RMC; all with conductors inside, ...or SEU cable. Take your pick.

Depends on JHA, around here it would have to be imc, rmc, or aluminum....check your wire size too.

Speedy Petey

Friday, I do think you should make certain you point out your location.
Chicago has it's screwy rules about conduit only. The rest of the country is vastly more typical.

It's in California and is zoned commercial. The building is not an MDU, and is owned by an association. I can't find anything in my 96 codebook, I'll call the bldg dept tomorrow to find out for sure.

Speedy Petey

What is an MDU?

You are still under NEC '96??? I didn't think anyone still was.


The only restrictions will be local. Best to check.

Speedy, you are correct. It seems alot of people have a problem about this areas specifics, but after doing both romex and pipe, I still prefer pipe.

wirenut

as stated above always check with JHA, no sense doing things twice. But I have never been told rigid was not enough

ATS

Check with AHJ, yeah I agree. You'd think that someday they would come out with a national standard, you know, like a book that all electricians nationwide could just reference for any question they needed answered, instead of having to call the individual inspector. Thank you Mr. Inspector.
