 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 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 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 3 conductors are in a raceway.
