Note:
If a temporary source of control power is required – verify control-power source
is of the proper voltage per the breakers nameplate or the specifically provided
schematic drawings with the breaker and switchgear.
When control power is connected to the circuit breaker, the closing spring will automatically
begin to charge.
1.
Open control-power circuit by opening the control power disconnect device.
2.
Connect control power to proper charging motor pins of secondary or fixed
mounted breaker top terminal block
3.
Energize (close) the control power circuit disconnect.
4.
Use the Close and Open controls (refer to Figure 1 page 15) to first Close and
then Open the circuit breaker contacts. Verify contact positions by visually
observing the OPEN/ CLOSED indicator on the circuit breaker front panel. Use an
ohm-meter to verify contacts are closed electrically and provide dual verification
of the front panel indicator.
5.
De-energize control power by repeating Step 1 above. If a secondary connector
umbilical cord was used for temporary control-power connections, disconnect the
umbilical cord from the switchgear first and next from the circuit breaker.
6.
Perform the above mentioned spring-discharge check again to verify that the
closing spring is discharged and the primary contacts of the circuit breaker
vacuum interrupters are open.
Final mechanical inspections without control power
Make a final mechanical inspection of the circuit breaker.
Verify the contacts are in the open position and the closing spring is discharged.
Check for loose hardware.
