Section 3. Description and Principles of Operation (cont.)
CAUTION: The green ground wire and test connector
must be connected to the breaker before the power is
turned on.
OPERATION OF TEST CABINET: (Circuit breaker must be
out of its cubicle)
1. Make sure both CONTROL POWER switches are in the
“OFF” position.
2. Connect the green ground wire to the breaker frame.
3. Plug the TEST CONNECTOR into the breaker
secondary disconnect. Use only the secondary
disconnect on the top right of the breaker (viewed
from the front of the breaker). Make sure the TEST
CONNECTOR is fully engaged into the breaker
secondary disconnect.
4. Turn the CLOSE & TRIP power switch to the “ON”
position. The trip power and close power indicating
lights should be illuminated. If any of the indicating
lights fail to illuminate, check the appropriate control
power fuse(s) located at top. If the fuses are not
blown, check the lamp in the indicating light
assembly.
5. Move the CHARGE MOTOR CONTROL POWER switch
to the “ON” position to charge the closing springs.
The charge control power indicating light should be
lit. The charge switch can remain in the “ON” position
during testing.
6. The circuit breaker close and trip circuits can now be
exercised by operating the CLOSE/TRIP switch on the
test cabinet. Operation of the breaker auxiliary switch
can be verified by observing the RED and GREEN
indicating lights on the test cabinet.
7. Network Interlock Set coil operation (when equipped)
can be verified by rotating the NWI switch to the left.
Network Interlock Reset coil operation (when
equipped) can be verified by rotating the NWI switch
to the right.
8. When breaker testing is complete, turn the CONTROL
POWER and CHARGE switches to the “OFF” position.
Pull the TEST CONNECTOR out of the breaker
secondary disconnect. Remove the green ground
wire from the breaker frame.
9. Discharge the charging spring before attempting to
install the breaker into its cubicle.
Section 4. Installation
The test cabinet should be installed on the wall at a
location where maintenance and testing of the breaker
can be conveniently done.
Conduits may be installed for cables to supply control
power for testing. Two 1-inch diameter holes are located
on the left side to accommodate wiring. Refer to the
wiring diagram in Figure 2 for control power connections
and jumper positions.
Section 5. Maintenance
Aside from keeping the unit clean and dry, the most
important requirement is to return the clamp to the
cabinet area when not connected to a breaker.
