No you can not. You need a 4 wire feed from your main panel, 2 hots a neutral and a ground..Hi,
I am looking at adding a subpanel in my garage. The previous owners had a hot tub on the back deck so there is a 220v panel, but the hot tub is gone. I want to move the wires into the garage and add a subpanel to use for my 220v table saw.
There are two 6 gauge hot wires ran from the main panel to there and a ground wire that goes to a ground rod, no neutral.
Can I take a subpanel and put the two hot wires to it and connect the ground wire to the neutral bar?
