Hi, I live in NH and deal with PSNH. I have an existing QR water heater service that is getting relocated. My question is do I need to run a nuetral to the disconnect in the house if a nuetral is not needed? Also can it be only rated 30 amps and #10 wire run as only the water heater is on this feeder and disconnect? (that is the way it is installed now) Any NH electricians out there can help me out?
