3h: Field Wiring
3h.1: Wire Sizing
Wiring must comply with all applicable codes and ordinances. Warranty is void if wiring is not in
accordance with specifications. Copper wire is required for all power lead terminations at the unit.
The units have single point power connection. A single field supplied fused disconnect is required.
The control transformer is factory mounted.

NOTES:
1.
Voltage within 10% of nameplate rating.
2.
Phase imbalance within 3%.
3.
Single conductors should be used for power connections.
4.
Single point disconnect of electrical supply to the unit is required. This supply must be fused.
5.
Field Fuse Size for recommended and maximum is based on the use of a time-delay fuse.
6.
Compressor RLA values are for wire sizing purposes only and do not reflect normal operating
current draw at rated capacity.
7.
All terminal block connections must be made with copper (type THW) wire.
8.
All field wire size values given in the table apply to 75°C rated wire.
9.
Ampere correction factors must be applied for ambient temperatures in sizing the power lead
wire. Refer to the local electrical code handbook.
10.
For Heat Pumps fitted with optional Boosters, please refer to the equipment nameplate for
maximum current draw, the circuit breaker, or similar device supplying the unit should be one
current range above that of the equipment nameplate.
