E. The CPT Harness will connect the CPT to the
Trip Unit. Temporarily position the plug-in
connector of the CPT Harness near the right
side of the Trip Unit. Route the CPT Harness
down along the inside of the right Breaker
frame, then across the bottom of the Breaker,
past the Copper Connectors, then to the
CPT Assembly.
F. Cut the CPT Harness to a suitable length for
connection to the CPT Terminals. Strip an
appropriate length of insulation and attach a
.138" ring terminal to each wire of the CPT
harness. Connect the wires to the X1 and X2
terminals of the CPT Assembly.
NOTE: The High Voltage (HV) Wires have a
LOAD Side and a LINE Side. The HV Wires
must be installed in the correct orientation
during the following procedure. For the
purpose of identification, the words “Load
Side” are marked on the female fuse
receptacle of each HV Wire.
NOTE: The Load Side HV Wires are longer
than necessary and are cut during the
following steps. Before cutting the wires, be
sure that sufficient length is left so that the
connections can be made to the correct
terminals on the CPT.
G Position the HV Wire Fuses in an accessible
location, as shown, then mark and cut the Load
Side of each HV Wire. Strip an appropriate
length of insulation from each Load Side HV
Wire and attach a .138" ring terminal to each.
Attach the HV Wires to the CPT terminals to
achieve the required voltage. (See the
following table.)
Voltage Required CPT Terminals Used
600 Volt Circuit H1 & H2
480 Volt Circuit H1 & H4
240 Volt Circuit H1 & H3
208 Volt Circuit H1 & H2
NOTE: The terminals to which the Load
Side HV wires are connected determine the
voltage of the CPT which, in turn, limits the
voltage of the Breaker. Verify that the line
voltage of the circuit matches the CPT
voltage BEFORE putting the Breaker into
service.
