 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 (3) conductors are in a raceway.
k Maximum size of the time delay fuse or HACR type 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.
 Maximum KW that can operate with the heat pump on is 4KW. Full heat available during Emergency Heat Mode.
 Maximum KW that can operate with the heat pump on is 10KW. Full heat available during Emergency Heat Mode.
 Maximum KW that can operate with the heat pump on is 9KW. Full heat available during Emergency Heat Mode.
 Maximum KW that can operate with the heat pump on is 8KW. Full heat available during Emergency Heat Mode.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses & conductor wires in accordance with the National Electrical Code & all
local codes.
NOTE A: -C Models have Rotary Disconnect. C0C 460V circuit breaker only available for 0KW. All electrical ratings are the same.
