1
Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
2
Based on 75°C copper wire. All wiring must conform to NEC 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 (3) conductors are in a raceway.
IMPORTANT:
While this electrical data is presented as a guide, it is important to electrically connect properly sized
fuses and conductor wires in accordance with all existing local codes.
