TYPE VCP-W ELECTRICAL GROUND & TEST DEVICE (SIMPLE)

PURPOSE

The VCP-W Electrical Ground and Test Device is designed for insertion into a

Vac Clad-W switchgear compartment to provide a safe and convenient means to:

1. Ground the circuit for maintenance work

2. Apply potential for cable testing

3. Provide access to line circuits for "Phasing Out" tests.

CAUTION: Because of the unique application and vast variety of

system/user requirements, specific operating procedures must be

developed by the user.

DESCRIPTION:

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. In an upper compartment, the

opposite normally holds true., the top terminals connect to the incoming line or

feeders and the bottom terminals connect to the main bus. This must be verified

for each application. Because of this two-high arrangement, there are two styles

of the Electrical Ground and Test Device. In the lower compartment, the

Electrical Ground and Test Device would normally provide connections to the

bottom terminals, see Figure 1. In the upper compartment, the Electrical Ground

and Test Device would normally provide connections to the top terminals, see

Figure 2. Again, the bus arrangement must be verified for each application.
