SECTION 6. FOUR-WIRE GROUND
FAULT OPTION
The ground fault option for four-wire installations
requires the installation of an additional current
sensor on the neutral bus in the equipment. The
sensor is connected to the trip unit through the
connector provided in the wiring harness.
1. Mount the neutral sensor on the outgoing neutral
lead, normally in the bus or cable compartment
in the equipment. Figure 45 shows the sensor
outline for K-3000, K-3000S, K-4000, and K-4000S
breakers.
2. Connect the neutral sensor wire harness to the
correct terminals on the sensor. To maintain the
same polarity as the phase sensors, connect the
white wire to the common terminal, black to the
tap.
3. Route the wires through the equipment and con-
nect to the two-pin connector on the trip unit wir-
ing harness. The wires should be tied to the
breaker frame in an easily accessible location.
