How many amps does a 10 HP 3 phase motor draw?

What size breaker do I need for a 10 hp motor?

Full Load Current: Three Phase AC Motors

Motor Horsepower Size Breaker
5 230V 460V 15 15
7-1/2 230V 460V 40 30
10 230V 460V 50 30

How do you calculate 10 hp motor current?

A 10 HP AC single phase motor has 230 Volts of voltage flow with 0.86 power factor, calculate the current. AC Current = 746*10 / (230*0.86) = 37.71 Amps.

What size breaker do I need for a 3 phase motor?

Breaker size must be rated for a minimum of 125% of the full-load current of the motor it is protecting, rounded up to the next standard breaker size. For example, the full-load current of a 5 HP motor at 460V is 7.6 Amps. The breaker must be sized for 7.6 * 1.25 = 10 Amps .

Why do we use 1.73 for three phase?

In a three phase circuit, the use of the constant 1.732 results from the fact that not all three phases are producing the same amount of power at the same time. … Suffice it to say that the correct power from a three-phase system at any point in time is found by multiplying by the square root of 3.

  1. Single-phase AC. I = P * 746 / (V * PF * η) ;
  2. Three-phase AC, line-to-line voltage. I = P * 746 / (√3 * V * PF * η) ;
  3. Three-phase AC, line-to-neutral voltage. I = P * 746 / (3 * V * PF * η) .

What is full load current of a 3 phase motor?

For three-phase, full load current for the resistive load is equal to the three-phase power divided by 1.732 times of voltage. Here power factor will be unity for resistive loads. Full load current I, I =P.
