We are re-routing the supply line to our pump house, where there is an extension panel with 30A 220V (pump controller) and 15A & 20A 110V breakers. It's about a 60' run from the 200A main service in the house, being placed in conduit 2' underground. The wire in place is newer 10 gauge solid copper. Is this sufficient, or what should we use?
Thanks.
