Electrical Data
MCA = Minimum Circuit Ampacity
MOP / MOCP - Maximum Overcurrent Protection / Breaker Size
Minimum Circuit Amps (MCA) and MOCP values in the above table are calculated in accordance with The NEC.Article 440
Electrical Requirements
Wire Size Use ONLY wire size recommended for
single outlet branch circuit.
Fuse/Circuit
Breaker
Use ONLY type and size fuse or HACR cir-
cuit breaker indicated on unit’s rating guide.
Proper over current protection to the units is
the responsibility of the owner.
Grounding Unit MUST be grounded from branch circuit
to unit, or through separate ground wire
provided on permanently connected units.
Ensure that branch circuit or general pur-
pose outlet is grounded.
Wire Sizing Use recommended wire size given in tables
and install a single branch circuit. All wiring
must comply with local and national codes.
NOTE: Use copper conductors only.
Electrical Rating Table
NOTE: Use copper conductors ONLY. Wire sizes are per NEC.
