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 Electrical Code (latest revision), article 310 for power conductor sizing.
4 Internal circuit breakers are standard on W12A2-A models.

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.
