I want to wire a 220 volt submersible pump to a temp power set up from a transformer. I need to bury 300 ft. of wire so I can get my well running. I was wondering if I could use 3-10 AWG TYPE MTW GR1 600 VOLT UL WIRE? They are single strand wires and are not connected. The wire coming out of the well head is a 10-2 flat with ground. This is only temporary until I build a house on the lot in a couple of years. Then it will be wired to the power panel in the house. Thanks
