does a 1-1/4" EMT stubbed up through the concrete slab into a detached garage have to be bonded?" by the way it was also installed outside the wall"

i was thinking that i would need an emt connector and a bushing on the exterior side and have to set a box on the inside in order to bond the conduit via the EGC in the 10-2 W/G.

i thought it may be easier to just use 1/2" pvc, LB stubbed into the wall and abandon the stubbed up EMT...

i beleive article 250.86 EX 2 releives me of grounding the sleeve.

thanks for any thoughts...

250.86EX2 (2002) would seem to concere with 334.15B

Q's arise here;

What is a 'short section'?

Why does a 'short section' remain ungrounded , when an elbow does not?
EX 2 vs. EX 3

if its metal bond it. Thats why PVC is much easier to work with No bonding requirements.
Also any parallel pathes from garage to house need a 4-conductor to the panel.

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 figured he was right..

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 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 ?

straighten us out here please!
