Plugs and receptacles for a 240/250-volt circuit can come in a number of configurations . Unlike Metal Halides that worked better with more juice, and even required a pulse start setup for optimal performance, the LEDs just do not need it. Two wiring configurations, Wye and Delta, indicate the wiring methods for three-phase motors. Medium Voltage:greater than 1000 volts and less than 100 kV 5.3. A basic understanding of electricity is helpful. In the US 120 / 240V 1 Single phase uses phase voltage, 2 phase uses line voltage, split phase uses 2 lines, a neutral and usually a capacitor to simulate a third phase (it's a method of motor wiring) It is possible to use more than 3ø, it's easiest to think of phases like the piston and con rods on the crank shaft of an engine.
