5. Maximum HACR is based on 225% maximum plus 100% of the rated load amps for all loads
included in the circuit, per circuit, per UL 1995 Fig. 36.2.
6. The “INCOMING WIRE RANGE” is the minimum and maximum wire size that can be accommo-
dated by unit wiring lugs. The (1), (2), (3) or (4) preceeding the wire range indicates the number
of termination points available per phase of the wire range specified. The (1-2), (1-3),or (1-4)
preceeding the wire range indicates that a single multi-terminal lug is available per phase that
can accept from two (1-2) to four (1-4) wires of the wire range specified. “(1 ) #1-600MCM OR
(2) #1-250MCM” indicates that a single lug is supplied and it will accept a single wire up to
600MCM or 2 wires up to 250MCM. Actual wire size and number of wires per phase must be
determined based on ampacity and job requirements using N.E.C. wire sizing information. The
above recommendations are based on the National Electric Code and using copper connectors
only. Field wiring must also comply with local codes.
7. A ground lug is provided for each compressor system to accommodate field grounding con-
ductor per N.E.C. Article 250-54. A control circuit grounding lug is also supplied. Incoming
ground wire range is #6 - #2/0 (50 - 90 Tons) or #6 - 350 MCM (95 - 230 Tons).
