4.0 ELECTRICAL WIRING
Field wiring must comply with the National Electric Code (C.E.C. in Canada) and any
applicable local ordinance.
4.1 POWER WIRING
It is important that proper electrical power is available for connection to the unit model
being installed. See the unit nameplate, wiring diagram and electrical data in the installa-
tion instructions.
• If required, install a branch circuit disconnect of adequate size, located within sight of,
and readily accessible to the unit.
• IMPORTANT: After the Electric Heater is installed, units may be equipped with one,
two, or three 60 amp. circuit breakers. These breaker(s) 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 75°C minimum copper conductors only. See
Electrical Data in this section for ampacity, wire size and circuit protector requirement.
Supply circuit protective devices may be either fuses or “HACR” type circuit breakers.
• Power wiring may be connected to either the right, left side or top. Three

WARNING
Disconnect all power to unit before installing or servicing. More than one dis-
connect switch may be required to de-energize the equipment. Hazardous volt-
age can cause severe personal injury or death.
