Hi all,
I know as long as you keep the hots/neutrals separate for each circuit and don't exceed the box fill that it's OK to have multiple circuits in the same box. I'm wiring up a wood shop and I'd like to have 7 3-gang boxes along a cement wall. I'll be using 3/4" EMT to connect and running 12 awg THHN-2 wire. These will not be multi-wire branch circuits, but three separate circuits. The 120v circuits will be GFCI breaker protected.
In each box I want to put two separate 120v/20A circuits and one 240v/20A circuit. I know there is a way to tie the 2 - 120v single pole breakers together in the sub panel, but is there a way to have all three breakers (2 - 120V single pole GFCIs and 1 - 240V 2-Pole) tied together? These are Square D QO breakers. This way if anyone ever needs to work on the one of the circuits all three will be turned off.
