Replacement Circuit Breaker
necessary to reference anything in the circuit breaker compartment,
refer to the original instruction books supplied with the assembly.
Refer to Figure Set 3.3, depending upon the voltage rating of the
circuit breaker, for any parts identification required during these
installation procedures
a. The circuit breaker front cover must be positioned properly and
securely bolted in position before inserting the circuit breaker into
the circuit breaker compartment.
m
WARNING
EXAMINE THE INSIDE OF THE CIRCUIT BREAKER COMPARTMENT BEFORE
INSERTING THE CIRCUIT BREAKER FOR EXCESSIVE DIRT OR ANYTHING
THAT MIGHT INTERFERE WITH THE CIRCUIT BREAKER TRAVEL.
m
WARNING
KEEP HANDS OFF THE TOP AND SIDES OF THE FRONT COVER WHEN
PUSHING THE CIRCUIT BREAKER INTO THE CIRCUIT BREAKER
COMPARTMENT. FAILURE TO DO SO COULD RESULT IN BODILY INJURY, IF
FINGERS BECOME WEDGED BETWEEN THE CIRCUIT BREAKER AND THE
CIRCUIT BREAKER COMPARTMENT. USE THE HANDLE PROVIDED ON THE
FRONT COVER OF THE CIRCUIT BREAKER, OR USE BOTH FULLY OPENED
HANDS FLAT ON THE FRONT COVER.
b. Position the circuit breaker in front of the circuit breaker
compartment, and line up the guide channel on the rear right
hand side of the circuit breaker near the floor with the guide
rail on the right hand side of the circuit breaker compartment
floor. Once the circuit breaker is aligned with the circuit breaker
compartment floor guide, push the circuit breaker into the circuit
breaker compartment until the rail latch at the front of the guide
channel catches in a notch in the guide rail, and prevents further
movement of the circuit breaker toward the rear of the circuit
breaker compartment (Figures 5.5). The circuit breaker is now
in the ‘Test’ position, and secondary disconnect contact can be
engaged. (Figure 5.6)
m
NOTICE
AS SOON AS THE SECONDARY DISCONNECT CONTACT IS CONNECTED,
THE MOTOR WILL CHARGE THE CLOSING SPRING, IF THE CONTROL
CIRCUIT IS ENGAGED AND ENERGIZED.
c. To engage the secondary disconnect contact, lift the handle on the
front left hand side of the circuit breaker chassis to a horizontal
position. Once the rod is pointing straight out from the circuit
breaker, push it manually to the rear until the secondaries are
initially engaged. At this point, the small horizontal pin in the
handle will have engaged two slots in the lever, which is pivoted
immediately above the handle. To insure complete secondary
engagement, push down firmly on the curved end of the lever as
far as it will go, using your foot or hand. When using a foot, care
should be taken not to bend the lever by using excessive force.
