Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...

Art. 430, Part III provides the requirements for motor and branch-circuit overload protection. Because of inrush current, overload protection is separate from overcurrent and ground fault protection ...
