1/2 emt

[Richard Cranium]

How many 12 ga. wires can you run through 1/2 emt?
My next question is can you run more than one circuit using the same emt run?
thanks guys you always are great....Richard

What I am thinking about is running a separate circuit for a refer in the garage plus run a different set of wires to go past the refer to another 110 volt outlet.

Of course you can have multiple circuits in a pipe.

The max number of THHN #12's would be 9. You do need to keep in mind the number of current carrying wires in your conduit as may need to derate your wires.

Two circuits in one pipe is fine, and you'll have plenty of room for 12s.

up to 9 #12 thhn/thwn in 1/2"emt. Count varies with other insulation types.

Number of circuits doesnt matter.

Could possibly run 6 circuits.

Thank you guys very much...Richard

9 is the magic number
9 or less Edit:current carrying #12 Thhn conductors in one conduit still can be put on 20 Amp circuit breakers even after derating.
