480V electrical motor wiring data - NEMA amps, starter size, HMCP size for motors ranging 1/2 to 500 hp.
Power Source: The power source for a 480V motor is typically a three-phase electrical system. This means that there are three individual wires carrying current, each with a voltage of 480 volts. The wiring diagram will show how these three wires are connected to the motor.
In three phase applications, the 480 typically is stepped down to 208 VAC. Then, each hot leg off the step down transformer will be 120 VAC hot to neutral. From contributor J: You have what is called a 480Y service coming into your building. It is a 3ph 4 wire service. You have 3 hots, a neutral, and a ground wire.
