Block the Racking Port
Citadel breakers are racked into and out of their respective cells via a racking tool inserted
into the breaker’s racking port. The racking port is located at the center of the lower
portion of the breaker. The racking tool can be inserted into the racking port directly on
the front of the breaker with the switchgear door open or through the door’s racking port
opening with the switchgear door closed. The Citadel breaker has a shutter mechanism
that lowers a metal plate and blocks the breaker’s racking port if the Citadel Breaker is
closed.
YOU ARE NOT ALLOWED TO RACK A CLOSED BREAKER !
The Citadel works to protect Operators from attempting to do this by sealing off any
access to the racking port opening.
If an attempt to insert the racking tool is made (either directly through the front of the
breaker or through the switchgear door) and the tool does not insert into the breaker and
feels clearly like it is being impeded –
STOP !!
Verify the breaker’s condition and trip the breaker open before attempting to insert the
racking tool again.
The Citadel Breaker can ONLY be racked if the breaker is in the Open condition. The
Citadel will remain in that Open condition for the full time the breaker is traveling (racking)
between the Disconnect and the Connect positions, or as long as the racking tool is
inserted. The Citadel will only become operable to close after it is fully in the Connect
position or fully in the Disconnected position AND the racking tool is removed from the
racking port.
(Citadels can operate on the floor when removed from the cubicle).
