Can I safely run six #12 wires along with grounds inside 1/2" thinwall conduit.


If not can I do 4 #12's with their grounds. Thanks for the replies.

You do not need a ground if you use the EMT as the ground but if you want one you only need 1, not 1 for each circuit. You have not mentioned insulation type but I will assume THHN. You can run 9 conductors in 1/2" EMT and stay within fill limits.

You may need to de-rate the conductors.
