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.
