Option a: 100% of the continuous nonmotor load
Option b: 125% of the continuous nonmotor load
Option c: 100% of the full-load current rating of the highest rated motor
Option d: 125% of the full-load current rating of the highest rated motor

Answer 1

Feeder conductors supplying several motors, or a motor(s) and other load(s), shall have an ampacity not less than the sum of 125% of the continuous nonmotor load and 100% of the full-load current rating of the highest rated motor.

Step-by-step explanation:

According to the code reference, feeder conductors supplying several motors or a motor(s) and other load(s) need to have an ampacity not less than the sum of 125% of the continuous nonmotor load and 100% of the full-load current rating of the highest rated motor.
