120 208 Volt Wiring Diagram. Each leg phase provides power phase voltage at a unique angle phase angle to the center neutral. So if A-B B-C and C-A are all 240 volts then A-N and C-N will both be 120 volts but B-N will be 208 volts.

208V 3 Phase Power. The outlet should be wired to a dedicated 20-amp240-volt circuit breaker in the service panel using 122 awg cable. 208V 3 Phase power also goes by the names 208V 3 Phase 4 Wire and 208Y120V.

This 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.

It also has a centrifugal switch and starting capacitor. If no tester is present device is nonlocking straight blade. The auxiliary starting winding is displaced in space from the main winding by 90 degrees. When the main windings are connected in series 120 volts is used.
