4.2 Circuit Breaker Removal
These are the following requirements and steps for circuit breaker removal using the RRS-2-BE.
4.2.1 Requirements for Removal
The following removal procedure assumes that the following prerequisites have been met:
1.
The circuit breaker racking mechanism is in working order.
2.
The circuit breaker has been properly maintained.
3.
The circuit breaker is installed in the cubicle and OPEN
according to
manufacturer specifications.
4.
The tooling is connected properly to both the circuit breaker and the RRS-2-BE.
DANGER!
*For your safety please ensure that all personnel follow the personal protective
equipment rules and regulations along with following all of the manufacturer guidelines
at ALL times.
4.2.2 Steps for Removal
To remove the circuit breaker to the DISCONNECTED position, perform the following steps.
1.
Ensure the RRS-2-BE is properly setup and attached to the breaker using the
breaker specific tooling provided.
2.
Verify the circuit breaker is OPEN according to manufacturer specifications and
company safety policies.
3.
Exit the arc flash boundary with the pendant station.
DANGER!
*Exiting the arc flash boundary may prevent the operator from observing the circuit
breaker during repositioning, if this situation occurs we recommend acquiring the CBS
ArcSafe® camera system in order to remotely view the repositioning.
*Although the pendant station allows the operator to be away from the immediate arc
flash boundary personal protective equipment requirements must still be met at all
times.
4.
Ensure the emergency stop push button is deactivated by turning the button
clockwise to unlatch.
5.
Use the pendant station as discussed in the given RRS-2-BE tooling guide. If the
pendant retractile cord is not long enough for the operator to leave the arc flash
boundary additional pendant extension cords are available and the pendant station
and pendant retractile cord can be replaced with an optional radio remote system.
6.
Detach and uninstall the RRS-2-BE unit from the circuit breaker cubicle.
