1. Conductors from Receptacle are connected to the circuit breaker
as shown.
CIRCUIT BREAKER REPLACEMENT
1. Loosen the two screws #1 located on the mounting plate on the
load side of the breaker.
Note - only loosen enough for the mounting plate #2 to slide
from under the screw heads.
2. Remove the remaining two screw #3 that secure the mounting
plate #2 in place.
3. Loosen the breaker screws #4 that connect the breaker phase
locations to the conductors which are attached to the contact
block pins. Loosening of these screws will allow removal of the
breaker and mounting plate assembly.
4. Loosen and remove the four breaker mounting screws #5 which
secure the breaker to the mounting plate.
5. Discard the old breaker & four mounting screws #5. Insert the four
new mounting screws #5 through the back of the new breaker.
Fasten to the mounting plate #2 as shown. Cut off surplus length
of screw protruding through the plate and fasten the mounting
plate #2 to the inside of the cover #6 by reversing steps 1 to 3
above, making sure to tighten all screws securely.
