Step 11 - Push the “Push to Open” clapper to open the circuit
breaker.
Step 12 - Inspect the circuit breaker to assure it is in the open
position and the closing springs are discharged. Remove the
transparent CloSure
TM
Tool. Remove the tape from the cam and
stick the tape on the front right side sheet of the circuit breaker.
Record the date of the test and the operations counter reading on
the tape (Figures 6-14 and 6-15).
Step 13 - Evaluate the CloSure
TM
performance by comparing the
test tape with illustrations in Figure 6-16. If the marking is similar to
6-16A, measure the over travel “x”: If “x” is greater than or equal to
0.6 inches, the circuit breaker performance is satisfactory. If “x” is
less than 0.6 inches or if the marking is similar to 6-16B or 6-16C,
immediately contact the Production Integrity Center for Technical
Support at (412) 787-6518.
Step 14 - Remove the CloSure
TM
Tool. Reassemble the front cover
onto the circuit breaker. Return the circuit breaker to it’s original
configuration and setup.
