Re: Junction box extension of wire

The runs were done in the galvanized conduit with the water tight fittings for the small 10ft run from the breaker box to the area where it was brought into the attic to run the rest of the length.

So is that wrong? Do I need someone else to come look at this work before moving forward?

I don't want to finish off the garage to find out it needs to be redone again..

Actually, the area inside any conduit, run outdoors, is now considered a "wet location" so, the wire must have at least one "W" in its designation. The conductors in Romex is THHN. Pulling NM in conduit is allowed but risky, because it often overfills the raceway.

Strictly by Code, the conductors should be replaced with something like THWN.

Great.. so sounds like more money wasted if im going to have to have it re-done..

So the yellow 12/2 W/G Type NM-B wasn't suppose to be used with the conduit on the outside?

Is that cable good to use inside the garage?

Yes, in a non-commercial garage.
