Step 4: Installing the Sensors and Sensor
Harness
A. Remove the Finger Clusters from the top
Breaker Stabs. Save the Finger Clusters and
the mounting hardware for use later in the
Retrofit process.
Note: If a Breaker Mounted CPT was
ordered with the Retrofit Kit, two (2) of the
Finger Clusters were removed from the top
Breaker Stabs in Step 3.
B. Slide a Sensor over each top Breaker Stab with
the terminals facing up and the nameplate
facing out.
C. Install one (1) Sensor Spacer on the top and
one (1) on the bottom of each top Breaker Stab
as shown. Using the (6) .190-32 × 1.25" screws,
(12) flat washers, (6) lock washers, and (6) nuts
supplied, tighten the Sensor Spacers so they
“pinch” the top Breaker Stabs.
D. Using the original mounting hardware, reinstall
the top Finger Clusters.
E. Connect the ring terminals of the Sensor
Harness to the Sensors as shown. Refer to
Section 12 of the Retrofit Application Data,
supplied with the Retrofit Kit, for detailed wiring
specifications.
Depending on the Sensors supplied with the
Retrofit Kit, the following conventions apply.
Sensor Style No. 8184A38H01
X1-X2 = 400 A X2-X5 = 1200 A
X1-X3 = 600 A X1-X5 = 1600 A
X1-X4 = 800 A
Sensor Style No. 8184A45H01
X1-X2 = 200 A
