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.
