3 phase service
"The Kid" is putting in underground wiring to his outbuildings. For
now, power will come from the house to the shop. The shop sits twenty feet from a three phase line. future plans is to install a three phase service to the shop, cut the ordinal transformer out, and then feed one phase back to the house from the wiring being installed now. OK, a one phase house service has two 110 legs on the same phase opposite polarity to get 220 across the two hot wires, neutral is the center tap. As I understand it you in effect get three 110 hot wires 120 degrees apart in the phasing for three phase with the center tap for neutral. So, can you run single phase 220 off this? Need any special provisions installed now? He's putting in conduit - four wires - two hot, neutral and ground. Karl |
