How many watts is 1 hp at 480volts?

Answer 1

A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.

Answer 2

To convert horsepower (hp) to watts, you can use the formula: 1 hp = 746 watts. So 1 hp at 480 volts would be equivalent to 746 watts.
