TABLE 6
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.
