RHAL/RHBL Electrical Data – with Electric Heat
Installation of the U.L. Listed original equipment manufacturer provided heater kits listed in the table below is recommended for all
auxiliary heating requirements.
• Electric heater BTUH - (heater watts + motor watts) x 3.414 (see airflow table for motor watts.)
• Supply circuit protective devices may be fused or “HACR” type circuit breakers.
• If non-standard fuse size is specified, use next size larger standard fuse size.
• Largest motor load is included in single circuit or circuit 1 of multiple circuits.
• No electrical heating elements are permitted to be used with A Voltage (115V) air handler.
• J voltage (230V) single phase air handler is designed to be used with single or three phase
230 volt electric heaters. In the case of connecting 3 phase power to air handler terminal block
without the heater, bring only two leads to terminal block, cap, insulate and fully secure the
third lead.
• Do not use 480 volts electrical heaters on 230 volts air handler.
Electrical Wiring:
Power Wiring
• Field wiring must comply with the National Electrical Code
(C.E.C. in Canada) and any applicable local ordinance.
• Supply wiring must be 75°C minimum copper conductors only.
• See electrical data for product Ampacity rating and Circuit
Protector requirement.
Grounding
• This product must be sufficiently grounded in accordance with
National Electrical Code (C.E.C. in Canada) and any applicable
local ordinance.
• A grounding lug is provided.
