Calculate Size of Circuit Breaker for Motor NEC Standard | Circuit breaker size Calculation

Calculate Size of Circuit Breaker for Motor as per NEC Standard.
In this video proper reference from NEC standard is shown for selection of circuit breaker for motor loads. Also example is solved to select the size of circuit breaker for motor as per NEC standard 430.52
NEC standard specifies different selection criteria of circuit breakers for motors and lighting circuits.

This is the way of explaining with proper standard reference. Thanks

Schneider has motor circuit breaker GV... it can be adjusted to the right current. But should u adjust it to nominal current of the motor or how much?

Does the table 430.51 not provide the maximum allowable rating of circuit breaker? Shouldn't you select the next lower standard breaker size rather than the next higher size?

[pabloaromerol]

In the formula to calculate the motor current, is it missing the efficiency of the motor?

[kamaljim]

What will be the cable size ? 2.5 time or 1.2 times of rated current ?

where did he select the next higher size 75?
