What size breaker do I need for a 5 hp motor?

In fact code recommends a 60 amp circuit breaker for a 5 hp 230v motor, but with overload protection.

How many amps does a 5 hp motor use?

A 5 HP motor at 230V, 3PH is12.

Using the formula above, multiply 12.4 amps by 10% for a result of 1.24. Add this total to 12.4 for a total of 13.64 amps.

How do you convert HP volts to amps?

Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.

How many watts is a 1 hp motor?

One electric horsepower is equal to exactly 746 watts.

How many amps does a 1.5 HP well pump draw?
