Rock Crusher And 480 Volts Power Delta Or Y Configuration

Rock Crusher And 480 Volts Power Delta Or Y Configuration

You have 3 hots, a neutral, and a ground wire. The voltage between any one leg and ground will be 277 volts, and between any 2 hot wires will be 480 volts. 3 phase machinery runs off Delta voltage, which means you only run 3 hot wires and no neutral wire. If you mistakenly wire a 230 volt machine at 480, it will not run faster.
