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 3 conductors are in a
raceway.
