Terminal Lug Connections
Different versions of terminal lug connection hardware are used for various
connections in some configured input bays and configured output bays. One
example of a terminal lug is shown in
. Terminal lug connection
hardware varies in how many cables can be connected and what size of cables
can be connected. For details about specific terminal lug connections, see the
following tables. Make a terminal lug connection as follows:
1. Strip only enough insulation off the end of the power cable for the bare
cable to get all the way down the terminal to the point where it is in front
of the set screw for that terminal.
2. Insert the bare cable all the way down the terminal to the point where it is
in front of the set screw for that terminal.
3. Tighten the set screw for that terminal to the torque listed in one of the
following tables, securing the cable.

(1) To find the frame size of your circuit breaker, find the catalog number on the circuit breaker.
This catalog number begins with “140G” followed by the circuit breaker frame size, “-M”, “-N”,
or “-R”. Use the corresponding torque value.
