In North America the calculations for people in the trade comes from the CEC or NEC electrical code book. The table states what the rating or setting of over current devices for the protection of motor branch circuits should be. If protected by time delay fuses the protection will be 175% of the motors full load amperage. Non time delay fuses the protection will be 300 % of the motors full load amps. The maximum setting time-limit type circuit breaker is to be set at 250% of the motors full load amperage.

What is the most suitable method of starting a 10hp motor with reduced inrush starting current?
The most suitable method for starting a 10hp motor with reduced inrush starting current is using a soft starter. A soft starter gradually increases the voltage supplied to the motor, allowing it to ramp up to full speed smoothly, thereby minimizing the initial surge of current. This method helps reduce mechanical stress on the motor and connected equipment, improving reliability and longevity. Additionally, it can enhance energy efficiency during startup.

Why using on motor star delta starter?
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
Why you use DOL starter in starting of motor?
because of starting current of induction motor is very high and it damages the insulation of motor

What is a three point starter?
A three point starter is a device that is meant to help start a DC motor. A three point starter will start device without much starting current.

Which motor is used for starting engine?
Er... a Starter Motor?
FCMA starter principle and working during starting induction motor?
The FCMA (Field Control Motor Arrangement) starter principle involves controlling the field current to manage the starting torque and speed of an induction motor. During startup, the motor is initially supplied with reduced voltage to limit the inrush current, and the field current is adjusted to ensure smooth acceleration. As the motor approaches its rated speed, the field current is gradually increased to optimize performance. This method enhances efficiency and prolongs the motor's lifespan by preventing mechanical and electrical stress during startup.
What supply is needed to run a 22kw 3ph motor?
question is incomplete, I think you ask how much current consumed by this motor. for starting this motor we need a star/delta starter and a three phase supply.
