Maximum size of the time delay fuse or HACR type 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 Table 310 regarding Ampacity Adjustment Factors when
more than 3 conductors are in a raceway.
