Part of the scope in the project I'm on was to move the washer and dryer out to the back porch I closed in. The 110 was easy since the wiring was exposed and accessible in the ceiling and the home owner said there was 220 running to the pump house 4 feet away from the porch. I went to hook it up today and the pump doesn't have a ground wire on it. two hot wires with 110 but no ground going back to the house. If I hook this up to the dryer. (the pump will be unhooked) can I connect a ground rod to the ground wire and still make the circuit? I was kind of at a loss when I saw only two wires coming from the house.
