TABLE 12
Electrical Specifications
−
W**AC Series

Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.

Based on 75°C copper wire. All wiring must conform to the National Electrical Code and all local codes.

These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest
version), Article 310 for power conductor sizing.
CAUTION: When more than one field power 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 current carrying 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 the National Electrical Code and all local codes.
