Installing the Current Sensors
Install current sensors as shown in Figure 16 and 17.
Use existing holes in the breaker back frame to mount C/T
support plate.
Next install the wire harness to the Current Sensors as
shown in Figure 18 below:
Connect the CT leads from the trip unit harness to each
of the CT’s. The leads are labeled with the letter of the
corresponding pole (A is the right pole from the rear of
the breaker, B is the center, C is the left), and are also cut
to the appropriate lengths. Attached the white wire to the
terminal marked white.
Reattach the primary disconnect assemblies to all the
studs. To aid in reinstalling disconnect 3-1/4-20 ¾ long
screws are supplied in hardware package. These screws
are used (only) to help force disconnects onto their
corresponding studs. Disconnects are to be secured in
position using the original breaker hardware.
