Wayne, Others,
Thanks for the help. It looks as if all types of NM cable (NM, NMC, NMS)
are out as per the "dwelling" issue of a detached garage as per 334.10 . Then
conduit or metallic cable it is!


Interesting what one learns on newsgroups.

You could also ask the inspector if they allow NM.

Anybody help me out?

I agree with those who say that since a detached garage is not a
dwelling unit, the use of NM cable is subject to the requirements of
NEC 334.10(3). That means NM can only be used if covered by a 15
minute fire-rated finish, i.e. drywall. You could use MC instead.

Cheers, Wayne
