b. Check pole bases for cracks and cleanliness.
c. Check insulating links for cracks and cleanliness.

Check for tightness of adjustment locknut. d. Check crossbar for looseness by moving main contacts laterally (refer to Enclosure 6).

  • e. Check all tru arc rings are on the pins properly.

If replacements are required, assemble with flat side of ring to the outside. f. Visually check the physical condition of the cell interlock and verify proper operation of the interlock as follows: 1. With the breaker out of the cubicle at the test location, verify there is a minimum clearance of 1/4" between the cell interlock tab and the breaker trip bar. This will allow for a rise of the cell interlock arm position of approximately 1/8" when the breaker is inserted into the cubicle. Adjust the cell interlock tab as necessary to obtain the required clearance.

Manipulate the cell interlock tab in a sideways motion. Verify that movement is not excessive and does not reduce the clearance between the cell interlock tab and the breaker trip bar to less than 1/4" (excessive sideways movement of the cell interlock could cause this clearance to be reduced)

Using contact pyrometer,-measure the temperature of the U/V Trip Attachment frame (See Enclosure 6). Record temperature on Enclosure

7. b. Measure resistance between terminals
  1. 11 and #12. Record on Enclosure 7 and verify resistance is satisfactory.*

9.13.8 .The undervoltage attachment will be shipped with reset adjustment all "out" (i.e. minimum space between the fixed and*moveable reset arms), and therefore should remain in the TRIPPED condition with the breaker fully open. However, a false RESET usually bccurs during the installation and mounting process. Therefore, the itlitial step is to cycle the undervoltage attachment by manually moving the 'breaker toward the closed position to allow the undervoltage attachment to trip. NOTE: FOR FINITE OBSERVATION OF UNDERVOLTAGE OPERATION, BREAKER OPERATION IS OBTAINED BY MANUALLY PUSHING THE CENTER "M>VING ARCING CONTACT" IN A SLOW BUT CONTINUOUS MOTION. PUSHING ON ONE OF THE SIDE CONTACTS IS NOT ACCEPTABLE, AS THERE MAY BE SOME UNDESIRABLE COCKING OF THE MOVING ASSEMBLY, AND OPERATION BY THE "LEVER. HANDLE" IS NOT ACCEPTABLE BECAUSE THE RAPID MOVEMENT AND OVER TRAVEL SHOCK DO NOT PROVIDE A CRITICAL CHECK. 9.13.9 With the undervoltage attachment de-energized, and the breaker toward the closed position, confirm that the undervoltage attachment is in the TRIPPED condition as indicated by zero clearance between the trip lever and trip bar. (The trip lever will actually be suspending the trip bar about 1/4 inch). 9.13.10 Confirm that the "reset lever" pivot/lock screw is sufficiently loose. to permit movement between the fixed and -moveable "reset arms;" and loosen the locknut on the "reset lever"-adjust screw.

    • M3Q-2 9.13.11 With the moving main contacts in their full open position slowly increase the "reset lever adjustment" by turning the screw clockwise until RESET occurs. On initial adjustment, as much as 10 to 20 turns of the screw may be required.

RESET action will be indicated by an audible click, slight dropping of the trip lever and trip bar, and raising of the trip latch. 9.13.12 After RESET action has occurred in Step 9.13.11, turn the "reset adjust screw" additional Then relock the adjust screw and the pivot/lock screw. 9.13.13 Move the breaker toward the closed position until a TRIP occurs as denoted by a readily audible click, dropping of the latch, and kick-out of the trip lever.

Allow the moving assembly to move slowlf toward the open position and confirm that RESET occurs just .!!. the moving assembly comes ..!!!.! (See Step 9.13.11).

9.13.15 Repeat Steps 9.13.13 and 9.13.14 a* sufficient number of times to be assured that TRIP action (on closing motion) and RESET action (just as the moving assembly comes to rest on opening motion) are correct.
