Question 13099 of 749 · Maryland Journeyperson Electrician Exam
Why does the full-load current from Table 430.250, rather than the motor nameplate current, determine motor branch-circuit conductor ampacity for a general-purpose motor?

Correct answer to question 13099
- C: 430.6(A)(1) requires the table values for conductor and short-circuit device sizing
Explanation
430.6(A)(1) requires the table currents for ampacity and short-circuit and ground-fault protection, while separate overload protection is based on the nameplate current. The tables do not include the 125 % factor.
