I.B. 69C3067H06 Page 27 Once the VCP-T circuit breaker is in the TEST position with the secondary umbilical cord properly connected, it is ready to be levered into the CONNECTED position. Using a deep (1 inch/25 mm) socket and levering crank, engage the large drive nut on the front of the breaker cradle.

A great deal of effort has been spent in the design of all Cutler-Hammer vacuum circuit breakers, in order to eliminate the need for field adjustments of wipe or stroke. Refer to paragraph 6-7 for details on visually inspecting contact wipe.
I.B. 69C3067H06 Page 33 5-3 STORED ENERGY MECHANISM 5-3.1 MANUAL OPERATION A standard circuit breaker is a manually operated breaker WARNING with one shunt trip. The closing springs can only be charged manually. To manually charge the springs, insert one finger in the recess behind the charging handle and KEEP HANDS AND FINGERS AWAY FROM THE pull out.
I.B. 69C3067H06 Page 34 5-3.2 ELECTRICAL OPERATION For electrically operated circuit breakers, the springs are normally charged through the use of a rugged electrical motor operator (Figure 5-7). The springs can, however, be manually charged as just described in the previous section.
I.B. 69C3067H06 Page 35 with no more than two wires per terminal. Two male type secondary plug-in connectors are mounted on the top rear portion of the circuit breaker. The plug-in con- nectors are protected by a molded hood (Figure 5-14). When the front cover of the circuit breaker is removed, the top of each plug-in connector is exposed.
I.B. 69C3067H06 Page 36 NOTES 1. THE “SR” DEVICE HAS ADDITIONAL CIRCUITRY THAT PROVIDES A 0.2 SECOND SIGNAL PULSE FOR CLOSING OPERATION POWER MUST BE REMOVED AND THEN REAPPLIED FOR A SUBSEQUENT OPERATION. 2. THE “LCS” ACTS AS A “LOGIC” INPUT TO THE “SR” DEVICE. THE CLOSE SIGNAL PULSE WILL NOT BE SENT UNTIL THE BREAKER IS RESET. 3.

I.B. 69C3067H06 Page 47 SECTION 6: INSPECTION AND MAINTENANCE is imperative that an establised schedule be followed. To establish an exact schedule for a specific installation, use the following guidelines: 6-1 INTRODUCTION 1. In a clean, non-corrosive environment, inspect and WARNING maintain each breaker every 2000 operations or 3 years, whichever comes first.
