WebMay 6, 2024 · The easiest way to think of three phase is as three "hot" wires and one neutral wire. Between any hot wire and neutral you will measure (say) 230 volts AC and usually a single household will receive one hot wire and neutral. Several houses further down the street a house might receive one of the other hot wires and neutral. WebThree Phase Power. In three phase systems, there are three "hot" lines (L1, L2, L3). Often there will also be a neutral (N) and a ground (G). The neutral and ground should be bonded together at your service entry). The three lines are all 120 degrees apart from each other. Loads can be attached in either a wye or a delta configuration.
