Supply and Motor Lead
Wiring and Connections

Copper conductors only should be
connected to the compressor motor
due to the possibility of galvanic
corrosion as a result of moisture if
aluminum conductors are used.
Copper conductors are recommended
for supply leads in the starter panel.

Suggested starter panel line and load
side lug sizes (when lugs are provided)
are noted in the starter submittals.
These submitted lug sizes should be
carefully reviewed for compatibility
with conductor sizes specified by the
electrical engineer or contractor. If they
are not compatible, the electrical
engineer or contractor should specify
the required lug sizes for the particular
application. Ground lugs are provided
in the motor terminal box and starter
panel. The motor terminals are
supplied with connection pads which
will accommodate bus bars or
standard terminal lugs (crimp type
recommended). Terminal lugs are field-
supplied.
These connection pads
provide additional surface area to
minimize improper electrical
connections. Also, a

-inch bolt is

provided on all connection pads for
mounting the lugs. Figure J-1 illustrates
the connection between the motor
connection pads and the terminal lugs.
