Question: 1 / 400

Which table contains the ampacity values for branch circuit conductors for motors?

Table 310-15(A)(16)

Table 430.238-250

The correct choice is B because Table 430.238-250 specifically provides the ampacity values for branch circuit conductors that supply motors, which is essential for ensuring that the conductors can safely carry the current required by the motor while preventing overheating and potential hazards.

This table takes into account the unique characteristics and demands of motor circuits, such as the inrush current during startup, and offers guidance for selecting the appropriate wire size based on motor ratings, operating conditions, and conductor insulation types.

In contrast, while the other tables may provide information about conductors in other applications or under different conditions, they do not specifically address the ampacity values required for motor branch circuits in the same way that Table 430.238-250 does. Therefore, when working with motor circuits, reference to the appropriate table is crucial for compliance with electrical codes and maintaining safety.
