REQUIREMENTS, SPECIFIC OPERATING

1-0 INTRODUCTION

Type Vac Clad-W switchgear assemblies are designed 
with all the bus work completely insulated for safety. 
Since the current carrying parts are not readily 
accessible, type VCP-W Manual Ground and Test 
Device is designed for insertion into the breaker 
compartment to gain access to the primary stationary 
contacts. It provides a convenient means to: 

1. Ground a circuit for maintenance work;
2. Apply potential for cable testing; and,
3. Access both bus and line circuits for “phasing out”.

tests.

CAUTION

BECAUSE OF THE UNIQUE APPLICATION AND 
VAST VARIETY OF SYSTEM/USER 
REQUIREMENTS, SPECIFIC SAFE OPERATING 
PROCEDURES FOR THE USE OF THIS DEVICE 
MUST BE DEVELOPED BY THE USER. 

1-1 DESCRIPTION

The device consists of a drawout element that can be 
inserted into a circuit breaker compartment in the same 
manner as a type VCP-W circuit breaker. It includes six 
terminals and ground bus connections. Each terminal is 
isolated from each other and the ground bus connection 
by insulating barriers. The upper and lower terminals are 
accessible upon opening the respective front hinged 
door. The ground connection is located in the lower front 
section of the device. 

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, 
i.e., 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, the bus and the line
positions of the grounding and test device terminals will
vary depending upon whether the device is used in an
upper or lower compartment. Therefore, 

it is most

important that the bus or line terminals be correctly
identified for each compartment before using this
device.
