Which current is generally used to size motor branch-circuit conductors for a typical motor covered by the NEC tables?

Texas Journeyman exam practice question · Motors & Generators

Which current is generally used to size motor branch-circuit conductors for a typical motor covered by the NEC tables?

AThe overload relay trip current for the motor circuit described in the question
BThe utility service demand
The applicable table full-load current
DThe measured no-load current

Why C is correct

Motor branch-circuit conductor and short-circuit protection calculations generally use the applicable NEC table full-load current. Nameplate current is used for specified items such as overload protection.
