If the nameplate rating is 56 amps then that is the maximum amount of current that the motor should draw. If you are talking about the inrush current and not the run current, the current could get up to 300% instantaneously for five time cycles over full load amps. It is this condition that allows a larger size breaker or fusing to be used on smaller size wiring. The high current is not on the wire long enough to start doing physical damage to the insulation.

When starting a motor car a current of 80 Amps is drawn from the 12 volt car battery. How much Power is dissipated in the starter motor?

What is the difference between Full load Amps and Service Factor Amps on an electric motor?
Full load amps is the amperage at which the motor was designed to work at to achieve its rated horsepower. Service factor amps is the amount of a periodic overload at which a motor can operate without overload or damage. Continuous operation within the service factor amps will shorten the insulation and motor bearing life of the motor as the motor will be operating at a higher temperature than it was designed to.
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.
Motor 1 hp equals how many amps?
hp= 745.699872so if the rated voltage is 220 so 745.699872 /220=3.389 A
Fuse size for 7.5 HP 3 Phase 440 Volt Motor?
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps
What is the maximum amperage capacity of a Siemens breaker that is rated at 200 amps?
The maximum amperage capacity of a Siemens breaker rated at 200 amps is 200 amps.
What is the maximum current capacity of the circuit breaker rated at 150 amp?
The maximum current capacity of a circuit breaker rated at 150 amps is 150 amps.
What is the maximum current rating for the circuit breaker, rated at 150 amps?
The maximum current rating for the circuit breaker is 150 amps.
What is the difference between full load amps and running load amps?
Full load amps is the maximum rated amps that the motor should draw according to its nameplate rating. Running load amps is the actual amperage the motor is drawing at that point in time when the test is taken. Some motor loads vary depending on if the load is cyclic. The reading on this type of motor would be from no load amps to full load amps.
18kW motor will take how many amps?
To calculate the amps drawn by an 18kW motor, you can use the formula: Amps = Power (Watts) / Voltage (Volts). Assuming a standard voltage of 120V, the motor would draw approximately 150Amps. Note that actual amps will depend on the specific voltage of the motor.
How many amps and volts are in household current?
Electric current can be either direct or alternating. ... Current density can also be expressed in amperes. Depending where you live will depending on what the voltage is and the carried amps. In the U.S., a conventional 120 V outlet is rated for a maximum current of 15 A, and the upstream wiring and circuit breaker should be designed to tolerate that. In the UK: The maximum current that can be drawn from a single UK socket is 13 amps (13A) and the maximum that can be drawn from all the sockets on a single ring-main together is 32A.
Can a 12/2 wire handle 30 amps?
No, a 12/2 wire is typically rated for a maximum of 20 amps.

How many amps drawn a 110KW motor?
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
What is the difference between Full load Amps and Service Factor Amps on an electric motor?
Full load amps is the amperage at which the motor was designed to work at to achieve its rated horsepower. Service factor amps is the amount of a periodic overload at which a motor can operate without overload or damage. Continuous operation within the service factor amps will shorten the insulation and motor bearing life of the motor as the motor will be operating at a higher temperature than it was designed to.
How many amps should a vacuum cleaner have?
Amount of electric current flowing through the vacuum. Watts: Amps multiplied by the power voltage drawn. Most upright cleaners are 7 to 12 amps. Many canister models are 12 amps. The maximum allowable amps that can be plugged into a household outlet is 12 amps.
A 220 volt motor is rated at 4.0 amps is that 4.0 amps per leg or 2.0 amps per each leg?
The Full Load Amps, FLA is a rating for each winding of the motor. In this case the motor actually needs 4 amps running through it. As current needs to go somewhere (perferably not to ground) the 4 amps will circulate on you 2 Hots, the neutral isn't needed. 4A in, 4A out.
