I thought I had an active 220 wall plug that was originally for a dryer, so I ran an extension onto the wires coming from the sander and added the plug, only to find that the previous tenant had just chopped the line like 4 feet from the circuit box, and removed the 220 breaker from the circuit box. So I pulled the wall plug from the wall, moved it in between the circuit box and where the sander will be, installed a 220v breaker in the circuit box, and finally got everything up and going!! Now it's really getting exciting! haha.
