How do you calculate breaker capacity of 10 hp three phase induction motor?
Varghesechacko
The first thing you have to do is find the full load amps of the motor. The wire size feeding the motor has to be 125% of the full load current. The breaker is usually 250% of the full load current. If the voltage and amperage had been added to the question the exact breaker size could have been calculated.

What type and Capacity of Electric Motor is used in Printing Press?
capacitor start induction run motor
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Why most of the induction motors have 1440 RPM in India?
To calculate the speed of an induction motor use the following formula, RPM = Hz x 60 x 2/motor # of poles. To answer the question, most of the motors must have 4 poles.
Application of induction motor in industry?
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
What type and Capacity of Electric Motor is used in Printing Press?
capacitor start induction run motor
How do you start three phase induction motor?
Three Phase Induction Motor is self starting motor so you can start it by conneting to power lines directly if the power line capacity is sufficient.
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
What size of breaker is use for 75 horsepower 220 volts 3 phase induction motor?
500 amp breaker with 250 mcm cu conductors, NEC list this motor as drawing 192 amps X 250% = 480amps go to the next standard size of breaker which would be a 500.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
What is a decripition of Nikola Tesla induction electric motor?
AC Induction Motor
What size breaker is needed for a 125 hp motor?
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
Why most of the induction motors have 1440 RPM in India?
To calculate the speed of an induction motor use the following formula, RPM = Hz x 60 x 2/motor # of poles. To answer the question, most of the motors must have 4 poles.
Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.
Can a Squirrel Cage Induction motor can be converted to Slip Ring Induction Motor?
yes
