5. Racking the SecoVac VCB to Disconnected/Test Position
CAUTION
When racking the VCB from CONNECT to DISCONNECT,
or DISCONNECT to CONNECT, do not stop or pause at
any intermediate position. Failure to engage in either
CONNECT or DISCONNECT position will render the
VCB inoperable.
1.
With the VCB in the CONNECTED position and open,
close the door and insert the racking handle, Figure 29,
into the racking access hole located at the bottom of
the door, Figure 30, until the racking socket is engaged
with the racking drive screw.

Turn the handle counterclockwise to drive the VCB out
of the CONNECTED position. Do not stop turning until
the indictor flag clearly shows DISCONNECTED.
As the VCB moves, the position indicator will change to reflect
current position, Figure 32 through Figure 34, in the lower right
front of the switchgear compartment.
