So I'm wiring up my woodshop and I've got a question about branching a 110120 volt circuit off a 220240 circuit.
I'm running 12/3 for this circuit coming of a 20 amp 2 pole breaker. The thought for this specific circuit would be for my dust collector and air compressor. Right now both are 110120 and I'm just doing a shared neutral with one set of plugs in the box being one circuit and the other being the other circuit. Black and white to 1 set of outlets and red and white to the other.
But I was wondering if I upgrade my dust collector to one that requires 220240, could I run the 220240 and 110120 circuit with that same 12/3? So essentially black and white to the 110120 circuit and black and red to the 220240?
edit (black and red for the 220, not black, red and white)
