Selectable Ground and Test Device
SECTION 1: INTRODUCTION
The purpose of this book is to provide instructions for receiving and
handling, storage, installation, operation and maintenance of 150
VCP-W Selectable Ground and Test Devices. This selectable ground
and test device is designed to be used in existing Westinghouse,
Cutler-Hammer, or Eaton Type VCP-W metal-clad switchgear.
Type VCP-W selectable ground and test devices are designed for
insertion into the breaker compartment to gain access to the primary
stationary contacts. It provides convenient means to:
1. Ground a circuit for maintenance work;
2. Apply potential for testing; and/or,
3. Access both bus and line circuits for “phasing out” tests.
4. Depending on customer specification, key interlocks may be
deleted. Line/Load and Phase labeling may be optionally provided.
CAUTION
BECAUSE OF THE UNIQUE APPLICATION AND VAST VARIETY OF SYSTEM /
USER REQUIREMENTS, SPECIFIC SAFE OPERATING PROCEDURES FOR THE
