Question

Branch-circuit conductors supplying a single continuous-duty motor shall have an ampacity not less than _____ rating

A. 125% of the motor’s nameplate current
B. 125% of the motors full-load
C. 125% of the motor’s full locked-rotor
D. 80% of the motors full-load current.

Answer 1

Branch-circuit conductors supplying a single continuous-duty motor should have an ampacity of 125% of the motor's full-load current.

Step-by-step explanation:

When supplying a single continuous-duty motor, the branch-circuit conductors should have an ampacity not less than 125% of the motor's full-load current. This ensures that the conductors can handle the current required for the motor's continuous operation without overheating or causing issues.
