jMaximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors. k Based on 75°C copper wire. All wiring must conform to the National Electric Code (NEC) and all local codes.

l These "Minimum Circuit Ampacity" values are to be used for sizing the field power conductors. Refer to the National Electric Code (latest version), Article 310 for power conductor sizing. CAUTION: When more than one filed power conductor circuit is run through one conduit, the conductors must be derated. Pay special attention to Note * of Table 310 regarding Ampacity Adjustment Factors when more than 3 conductors are in a raceway.
