How come there is no neutral, how does the AC work? Is this in the US or EU? What is the line voltage there?
its 240 volt canadian. You have 2, 120 volt lines, 180 degrees out of phase. Technology Connections has a great video on it.
Wow... I've never actually heard a setup like this even exists... three phase, sure, we have it here even in households (I go it), but 180 degrees out of phase to get double the voltage... yeah, definitely a first for me.
So, the idea is to use the 240V line or have separate 120V lines? Cuz if it's the latter, just bring neutral over the ground (rewire in a junction box) and use the neutral as ground as well. Sure, not the best scenario, but it should get the job done if most of the stuff you plug in are power tools, which don't have ground anyway.
Ground wires in Canada are un-insulated, and not rated to carry continuous current. Huge electrical code violation doing this.
Better off just converting one of the hot wires to a neutral (tag the wire with white tape please), and moving the circuit to a single pole breaker.
