I only had one electrical outlet in the workshop, but the previous owners left several junction boxes in the ceiling. I had to move this one a few inches to make it accessible, and add my own socket, but now I have power for my computer and 3D printer station :-)
I couldn't figure out what circuit that junction box was on, so I cheated and just flipped the switch for the whole house while I installed the outlet. Only had to reset two clocks after I finished!

Totally forgot to turn the dryer back on though. Towels are still wet :-(
