What is the circuit breaker rating required for a motor with a 250 Ampere full load current?
A motor that is rated at 250 full load amps will need 400 amp time delay fuses or a 500 amp frame breaker with adjustable amperage trips. The wire size for this motor has to be 125% of the motors FLA. 250 x 125% = 312 amps. A 350 MCM copper conductor with an insulation factor of 90 degrees C is rated at 325 amps.
How do you make correct setting for overload of a 3 phase motor?
125 percent of full current rating of the motor
What size wire for a 3 phase 5 hp 460 volt motor?
At 600 volts the rule of thumb is one amp per horsepower. So a 20 HP motor would need 20 amp wire. The code book states that a 20 HP motor at 575 volts draws 22 amps. The conductor for a motor has to be 125% rating of the motors FLA (full load amps). 22 x 125% = 27.5 amps. A #10 copper conductor with a insulation factor of 60,75 or 90 degrees C is rated at 30 amps.
What is the amperage of a 400 HP 4160 volt 3 phase motor?
The formula you are looking for is I = kW x 1000/1.73 x E x pf. I = 1.5 x 1000 = 1500. 1500/1.73 x 400 x .86 = 1500/595 = 2.5 amps. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. A feeder for a motor has to be rated at 125% of the motors full load amps 2.5 x 125% = 3.1 amps A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
What size wire and breaker for a 30 hp 240 volt 3 phrase motor?
A three phase 30 HP at 240 volts draws 80 amps. Motor feeders have to be rated at 125% of the motors full load amps. 80 x 125% = 100 amps. A # 3 copper conductor with an insulation factor of 75 or 90 degrees C are rated at 100 and 105 amps respectively. Non-time delay fusing is 225 amps, time delay fusing is 125 amps and a circuit breaker is sized by 250% x 80, the full load amps, which equals 200 amps.
Who is faster Honda TMX 125 or Yamaha STX 125?
Of course TMX 125 is much more faster i believe coz thats my favorite motor.

What is the cable size for motor 15kw 440 volts connection?
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
How much power is generated by a D16ZC Honda motor?

What size wire for a 3 phase 50 amp compressor?
The North American electrical code states that a conductor for a motor must be rated at 125% of the motor's full load amperage. 125% x 50 = 63 amps. A #6 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 65 amps respectively.

How many amps does a 1 hp electric motor pull under a load?
T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps. Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.
