3. Open the CPT module door to verify the
secondary breaker, located on the CPT truck,
is in the “OFF” position. An interlock prevents
the CPT from being inserted unless the
secondary breaker is in the OFF position and
the slide moved towards the off position
(figure 25).
4. Close the CPT or PT module door (figure 26)
and insert the push/pull rod into the push/
pull port and turn the handle to release the
interlock lever. For PT or CPT elements in the
upper position, the push/pull extension may
be used to ease operation (figure 27). The
extension can be added by inserting the
extension into the push/pull tool and securing
it with a clevis pin. It can also be disassembled
for storage.

5. Push the rod into the compartment to insert the
CPT or PT element. The rod is held captive while
between disconnect and connect positions.
6. When fully inserted and connected, the rod can
be returned to its original insertion orientation
and removed from the push/pull port.
7. The secondary breaker can now be switched
to the “ON” position. To switch the secondary
breaker to the “ON” position, open the CPT
door and move the secondary breaker to the
on position. The slide will automatically move
towards the on position.
