classes of loads. In addition, they have high dielectric
strength, heavy-duty switching and withstand capabili-
ties, and high interrupting capacity.
3.2.2 SWITCH INTERLOCKS
Cutler-Hammer transfer switches are mechanically and
electrically interlocked to prevent the two sets of main
contacts from being closed simultaneously.
3.2.3 DRAWOUT INTERLOCKS
All switching devices are 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 THE SWITCH IN OR OUT WHEN THE
SWITCH CONTACTS ARE CLOSED WILL CAUSE
THE SWITCH TO OPEN.
The switching device will close only in the DISCON-
NECT, TEST, and CONNECT positions. The switching
device will not close in the WITHDRAW position.
