
Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.

Based on 75°C copper wire. All wiring must conform to the National Electric Code (NEC) and all local codes.

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 T
able 310 regarding Ampacity Adjustment Factors when more than 3 conductors are in a raceway
