I have a 220V water pump located approximately 150 feet from the house. The exterior grade direct bury romex type feed has a black, white, and bare copper. I would like to create a 110V outlet in the pump house.
Can I use the bare copper wire as my neutral going back to my service panel and create a new ground by clamping off the well casing, or is my only legitimate option to run new four wire romex back to the house?
