1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.

2 Based on 75° copper wire. All wiring must conform to the National Electrical Code and all local codes.

3 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.
