j 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 Electrical Code 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 revision), article 310 for power conductor sizing.
CAUTION: When more than one field power conductor circuit is run through one conduit, the conductors must be derated.
Pay special attention to Note 8 of Table 310 regarding Ampacity Adjustment Factors when more than three
conductors are in a raceway.
