SECTION 6: DRAWOUT MECHANISM
6.1 DRAWOUT INTERLOCK
The transfer switch is mechanically interlocked to the
drawout mechanism to ensure that the switching device
is always open when connecting or disconnecting it from
the line and load stabs.
LIFTING THE PADLOCK LATCH WHILE ATTEMPT-
ING TO RACK IN OR OUT THE SWITCHING DEVICE
WHEN THE SWITCH CONTACTS ARE CLOSED WILL
RESULT IN THE SWITCHING DEVICE OPENING.
THIS WILL RESULT IN A LOSS OF POWER TO THE
LOAD.
The socket wrench must be removed and the drawout
mechanism in an operational position for the switching
device to operate.
The switching device will close in the DISCONNECTED,
TEST, and CONNECTED positions. POWER WILL BE
DELIVERED FROM A POWER SOURCE TO THE
LOAD ONLY WHEN THE SWITCHING DEVICE IS IN
THE CONNECTED POSITION. The switching device
will not close in the WITHDRAWN position.
6.2 SWITCH POSITION
The drawout mechanism has four positions. They are
achieved by lifting the padlock latch and inserting a 3/4-
inch socket wrench (Figure 6-1). Clockwise motion
moves the switch towards the CONNECTED position.
Counterclockwise will move the switch towards the
WITHDRAWN position.
CONNECTED
The switch is fully connected to the primary stabs and
secondary contacts.
With both switches in this position the transfer
switch is fully operational.
TEST
The switch is not connected to the primary stabs,
but is connected to the secondary contacts.
DISCONNECTED
Both primary stabs and the secondary contacts
are disconnected.
WITHDRAW
The switch may be removed from the cassette.
6.3 ROTATION ON THE DRAWOUT
If the switching device needs to be rotated on the draw-
out for inspection,
