The amount of copper in a 125 hp electric motor typically ranges from 25 to 50 pounds, depending on the motor's design and construction. The copper is primarily found in the windings of the stator and rotor. Factors such as the motor's efficiency, size, and specific application can influence the exact copper content.

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 are the release dates for The Electric Company - 1971 125 1-125?
The Electric Company - 1971 125 1-125 was released on: USA: 14 April 1972
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?
125 hp and 107 ft lbs of torque.
How much horsepower does a Saturn sc1 have?
the single cam motor has about 100 hp abd the dohc has about 125 hp.
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.
What are the release dates for The Electric Company - 1971 385 3-125?
The Electric Company - 1971 385 3-125 was released on: USA: 12 April 1974
What are the release dates for The Electric Company - 1971 125B 6-125?
The Electric Company - 1971 125B 6-125 was released on: USA: 8 April 1977
What are the release dates for The Electric Company - 1971 515 4-125?
The Electric Company - 1971 515 4-125 was released on: USA: 11 April 1975
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.
What size wire is used for a 7.5 hp 240 volt single phase motor?
The rule of thumb for a single phase 240 volt electric motor is 7 amps for each horsepower. As this is a 7.5 h.p. motor you should use a 60 amp breaker wired with AWG # 6 copper to be safe.
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.
