Connecting 24vdc power supply to 110vac

[Demon]

110vac here in Québec has black and white wires. Which is N, which is L?

Hmm, won't let me edit.

I assume L is load (black wire connected to breaker), N is neutral (white wire to common bus bar).

Just wanna make sure.

in general... in US and I see in Canada..... L is for live or line..........(ps... don't kill yourself, or your dog)

Quick Answer: What Does N and L Mean in Wiring?
L (Line / Live / Hot): The conductor that carries voltage from the power source to your device. It can cause electric shock if touched.
N (Neutral): The return path that completes the circuit back to the source. In the U.S., neutral is bonded to ground at the main service but must be kept isolated from ground on branch circuits and subpanels.

It really doesn't matter as long as you connect 110V across the L & N connections.
Here in Sweden, we use Schucko connectors for 230V outlets and they're not polarised so depending on which way around you insert the plug live/neutral would be switched. The connected load doesn't care one bit and it doesn't make any difference. Some audiophools might not agree but lets not go there.

Now, with 3-phase it's obviously another story but that's not the case here.
