My garage has an AC, which is never used (its so wasteful to heat and cool the room! prefer just to put on a fan) Thinking that if i install a unit like this, i can break this in to two separate 20 amps circuits for outlets, or use the AC if i feel the need. https://www.amazon.ca/Baomain-Universal.../dp/B08HWM7CMR/

Anyone do something similar?

there are no outlets, so that doesn't work! I was hoping to add additional outlets, and have enough electrical friends i could bounce the ideas off them, but didnt realize the 240 volt wiring has 2 hots and no neutral, so i cant split 1 240 volt into 2 120 volt plugs!

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.
