When determining the percentage of the motor FLC for sizing, which table do you consult?

Table 430-32
Table 430-52
Table 430-152
Table 430-202

The correct answer is: Table 430-152

To determine the percentage of the motor Full Load Current (FLC) for sizing, the appropriate reference is Table 430-152. This table is specifically designed to provide the necessary guidelines and values for calculating the motor branch circuit protection and sizing of conductors based on the FLC of the motor. Table 430-152 provides information about the percentage of FLC that should be used for various types of motor applications, which is crucial for ensuring that the motor is adequately protected and that the wiring is appropriately sized to handle the load. This is vital for both operational efficiency and safety, preventing issues such as overheating or potential electrical failures. The other tables mentioned relate to different aspects of motor calculations and ratings. While they are all part of the NEC (National Electrical Code) sections relevant to motors, only Table 430-152 explicitly addresses the FLC percentages needed for proper motor circuit protection and conductor sizing. Thus, in the context of this question, Table 430-152 is the correct answer and the most relevant resource for the task at hand.
