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
3
/8-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.
