Four Wire Delta Circuits – Continental Control Systems, LLC
120/208/240 Volt Service240/415/480 Volt ServiceGeneral NotesThis is the most common four-wire three-phase delta service and is essentially a 240 volt, three-phase, three-wire delta service with one of the 240 volt transformer winding center tapped to provide two 120 Vac circuits, which are 180 degrees out of phase with each other. The voltage measured from this center tapped neutral to the third “wild” leg is 208 Vac service almost always has a neutral connection, but in some rare situations, the neutral conductor is not available. It generally e..See more on ctlsys
Understanding 220 or 240 volt Electrical Circuits
3) A white wire called the neutral which completes the electrical circuit for the 120 volt accessories only. 4) A bare copper wire called the ground, the sole function of which is to enhance user safety. At one time, the code allowed for one insulated wire to function as both ground and neutral in 120 / 240 volt combo circuits, but now all such
