|115 volt||575 volt|
What size breaker do I need for a 4 hp motor?
How to Calculate How What Size Circuit Breaker a Machine will Need:
|HorsePower of Main Motor||220 Volts, 1 phase||220 Volts, 3 phase|
|1 Hp||5.6 Amps||2.8|
What size breaker do I need for a 5 hp motor?
A 5hp single phase AC motor has a load current of 28 Amps. So 10GA. wire with a 30 Amp breaker will work.
What is the formula to convert HP to amps?
Knowing that we can write hp to amps formula for direct current (DC) as: I = P * 746 / (V * η) . As the SI unit of power is the watt, it’s common to convert units before estimating the amperage. A rule of thumb states that you should multiply the power in hp by 746 to get the power in watts.
