2011. 3. 9. · Elevator motor is 40 HP, 208 Volt/3-phase. Motor FLA from NEC Table is 114 Amps. Breaker sizing: 114 FLA x 2.5 = 285 Amps, round up to 300 Amp. Circuit Breaker #1 is in the Main Dist Panel "MDP". CB #1 is a 300 Amp thermal magnetic breaker, as follows: Siemens JD Frame, model number JXD63B300. CB #2 is inside the elevator machine room.

The below chart breaks down the values based on single phase or three phase power which would be the power supply in your area as well as standard voltages. You will need to know these two values to accurately determine the amp draw based on horsepower. An electric chain hoist uses a motor for the lifting operation.

How do I know how many amps my 3 phase motor is? 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.

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. Therefore, it is good practice to size the breaker at 15 Amps.

The most common use of three-phase power is for motors. It provides a unique feature which is a rotating field in order to rotate the motor without the need of a starter circuit. This is accomplished due to the fact that each one of the three phases has a different offset. How to Wire 3 Phase Motor to 240 volt system (STEP by STEP) Watch on

2019. 9. 15. · How many amps does a 1 hp AC motor take? AC current is calculated by the power factor of 0.86 for single-phase supply and 0.8 for three-phase supply. Look at the table the 1 hp motor takes will be 1.3 A at 440 Volts three-phase at the same time while using single-phase it takes only 3.8 Amps. Also 5 HP three-phase motor takes 6.4 Amps.
