Manual 2100-348

Page 5

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

j

Based on 75° C copper wire. All Wiring must conform to NEC and all local codes.

k

These “minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National

l

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.
