TABLE 8
Electrical Specifications
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.
