I received the power supply for the CNC machine I'm building about a week ago, and it's a bit smaller than I thought it was going to be. That's good - smaller is better.

I had to do a little research to figure out how to wire a power cord to the little box. The power line I used was from an old computer cable I had sitting around, and inside that cable was a white, black, green, and bare ground wire. The power supply had a spot for ground, "L" and "N", which I determined were for "lead" and "neutral."

Ground: bare wire and green wire.
N: white wire
L: black wire

Alternating current is so weird. DC is so much easier, with it's easy-to-remember black and red wire.

I tested the power supply with a multi-meter, and it's pushing out a full 24 volts. Good deal.
