* Use only copper wire for field connections to unit. Wire size is based on 60 or 75°C copper conductor at 86°F (30°C) ambient tempera

ture and ampacity shown in table. If other than 60 or 75°C copper conductor is used, if ambient temperature is above 86°F, or if voltage

drop of wire exceeds 2% of unit rated voltage, determine wire size from ampacity shown and the National Electrical Code. Wire lengths

shown are measured one way along the wire path between unit and service panel for minimum voltage drop.
