4.1 Power Wiring
It is important that proper electrical power is available for connection to the unit model being installed.
Refer to the unit nameplate, wiring diagram and electrical data in the installation instructions.
 If required, install a branch circuit disconnect of adequate size, located within sight of, and readily
accessible to the unit.
 When the electric heat is installed, units may be equipped with one or two 30~60 amp circuit
breakers. These breakers protect the internal wiring in the event of a short circuit and serve as a
disconnect. Circuit breakers installed within the unit do not provide over-current protection of the
supply wiring and therefore may be sized larger than the branch circuit protection.
 Supply circuit power wiring must be 167 ℉ minimum copper conductors only. Refer to electrical data
in this section for ampacity, wire size and circuit protector requirements. Supply circuit protective
devices may be either fuses or "HACR" type circuit breakers.
