This device is longer than the standard VCP-W breaker. Therefore:

1. Electrical Ground and Test Device must be handled with extreme care while

loading it on or removing it from the extension rails.

2. The extension rails cannot be engaged or disengaged with the device in the

"Test" position – the device must be either removed or in the "Connected"

position.

3. The device cannot be stored in a Vac Clad-W breaker compartment. It can

only be stored in a storage compartment.

The stored energy closing mechanism for the power grounding switch is the

same as used in the Type VCP-W breakers. It is capable of applying the ground

against a "Live" circuit if operational errors have not cleared the circuit. However,

in such a case, the relaying at the source of power is expected to cause the

source interrupter to clear the as THIS DEVICE HAS NO INTERRUPTING

CAPABILITY.

POWER GROUNDING SWITCH OPERATION:

CLOSING

The power grounding switch is closed by a control switch at the end of a 50ft.

long cable (supplied with the device). The control switch is a spring-return type

to the neutral (unlabeled) position. Upon turning the control switch to "Close"

position (note that the control switch does not have to be held in the "Close"

position):

1. The closing springs start to charge

2. After the springs are fully charged, they automatically discharge to close the

switch contacts.
