How do you calculate amps on a 3 phase motor?

Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.

How much electricity does a 10 hp motor use?

If the motor is loaded to 10 hp, which it probably isn’t, its drawing 746 watts per hp divided by the efficiency, probably about 90% for a motor that size or a total of 8.29 KWH for each hour it runs. At 14 cents per KWH, that would be $1.16.

How many amps does a 1 HP pool pump draw?

The 1 HP Power Flo Matrix PN SPX1510Z1XE is rated for 12 amps.

How much current would a 1.5 HP 240v motor draw?

The 1.5 HP Baldor motor that turns at 1725 will draw 18 amps according to its name plate.

How do you measure a breaker 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 .
