hi, thanks for the replies...i got a customer who has a detached garage...whoever poured the foundation told the homeowner to go to lowes and get a 1-1/2 emt 90 to use as a stub up. the 90 is even outside the wall on the inside of the garage!
the homeowner asked me to use it but i declined and just went with pvc.
i was just wondering whether or not IF it were used would it have to be?
i spoke to an inspector that just said.."don't go there"...
I've had to jackhammer out more than a couple of slabs where EMT has been stubbed through them, and has rotted out below the slab. Your idea to not use it is a good one. ***And now, the big bomb*** (250-32 again) How do you plan on grounding?
ah, 250-32, my favorite code! but wait! lemme see, 10-2 w/g per 225.39(b) 30A, 2 circuits max, ok that seems Kosher assuming a 2-cir can....so.....unless this is ONE 30A circuit for a welder, we run a G-rod from the noodle bar of course the #10 could be for V-drop, and is for a 20A branch no OCPD's ?
