We have a water pump way out in the field (500+ long wire run) that is wired for 220 with two wires - no neutral.
It would be very, very convenient to have a power outlet at this site for tools, etc. However, my electrician said there is no way to add a normal 110 outlet because there is no neutral.
One option is to run a neutral (or maybe run a standalone 110 circuit) in a new conduit, but 500 feet of new underground conduit is a very big job.
Is there any way to (safely, code compliant) get a 110v outlet at this site without running new wires ?
