:
The Dummy Circuit Breaker Device is designed to provide a means of isolating a section of switchgear or buswork.
The device WILL NOT function as an interrupting device. The device consists of a solid run of copper bus connecting
the Line and Load side of switchgear. Primary Disconnects are of the same style as those for the the ADVAC circuit
breakers and G&T devices. Refer to the table below for replacement parts.
Insertion and racking of the Dummy Breaker Device is similar to the circuit breaker, however there are only two
positions; Disconnect and Connect. No position release is required. The automatic ground on the device makes
connection when the device is inserted into the cell in the Disconnect position. The ground remains in contact
throughout the racking process. The device MUST NOT be racked into or from the Connect position when the circuit
is energized. Verification that the circuit is de-energized must be made before racking the device.
DANGER
pen Coil is not rated for
INSERTION OR REMOVAL OF THIS DEVICE TO OR FROM THE
CONNECT POSITION WHILE THE PRIMARY CIRCUIT IS
ENERGIZED WILL RESULT IN AN ARC FAULT AND POSSIBLE
PHYSICAL INJURY OR DEATH.
Kirk Key interlocks are provided to lock the device in the Disconnect or Connect. These locks provide an added
measure of safety; however, ALL other safety procedures and verifications MUST be followed to avoid the possibility
of a fault during racking.
