How are most guys doing this? What I'm hearing is only pull 3 #12 curcuits in 3/4" conduit. Is this what most guys are doing?
Please correct my math. If I pulled more, say 9 current carrying #12 conductors. Than it would be 2400w, derated to 1680w. So I could load the circuit up to 1680w.. (taking into consideration continuous loads)
I would like to know what most guys are doing. My background is residential, commercial is a different animal I'm still trying to grasp.
You could put 4 multiwire single phase circuits in a conduit. That looks like 8 circuits at 120v. 310.15(B)(4)(a) If you didn't have any harmonic loads it could be 3 3p wye multiwires for 9 120v circuits.
