SECTION 7. 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 18 shows the outline of the neutral
sensor.
2. Connect the neutral sensor wire harness to the
correct taps 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 connect
to the two-pin connector on the trip unit wiring
harness. The wires should be tied to the breaker
frame in an easily accessible location. They may be
located with the communication harness.
