TABLE 4A
Electrical Specifications H***A Series

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.

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.
* Top outlet supply option is available only factory installed and only on the selected models.
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 (3) 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.
