Hi everyone. I bought this house about a month ago and in the garage had a brand new subpanel installed. Cool I thought. Im out in the garage tonight setting up my shop to start some steel fab and I notice that this sub is there just for 1 220 plug. I decided to add more outlets so I pulled the cover and it is just 2 hot leads no nuetral or ground wires at all. Do I really need to run a neutral line all the way back to the main to get some more 120 in there or can I run neutral a different way? Maybe to a freshly installed grounding rod?
