    The Electrical Ground and Test Device is a drawout element that can be inserted into a circuit breaker compartment in the same manner as a type VCP-W circuit breaker, see Figure 2.0.1. Vac Clad-W switchgear is a two-high arrangement. In the lower compartment the top terminals normally connect to the main bus and the bottom terminals normally connect to the incoming line or feeders.

    Figure 2.1.2.2. The “OPEN” push-button must be depressed. For safety reasons, the switch is prevented from opening in less than 20 seconds after closing. 2.2 VCP-W INTERLOCKS AND SAFETY FEATURES The device is designed to provide as many interlocks and safety features as practical for the personnel performing any of the operations described earlier.

    G & T device "OPEN". In the Cutler-Hammer design, the K2 lock function is not needed. It is not possible for an operator of the G & T device to manually charge the closing springs or to manually close the device to ground. Therefore, the K2 lock will be a two cylinder transfer key lock for consistency with the Con Ed operating procedure, see Figure 2.3.2.

    "OPEN"/"CLOSE" push-button station, See Figure 2.3.6. In the Cutler-Hammer design, the selector switch functions as described below. In the "OFF" position, the G & T device is electrically disabled. The selector switch is padlockable in the "OFF" position. This provides the padlockable function for the Key Locks K1 and K2.
  • Page 9 See Figure 3.2.7. Remember, the G & T device is longer than the standard VCP-W breaker. Optional use of a ramp for the BOTTOM (floor level) switchgear compartment. Engage the ramp onto the fixed rails of the switchgear bottom compartment. Push the G & T device onto the ramp checking to insure the wheels of the G &...
