50/75/150 VCP-W 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 USE OF THIS DEVICE MUST BE DEVELOPED BY THE USER.
WARNING
SATISFACTORY PERFORMANCE OF SELECTABLE GROUND AND TEST DEVICES IS CONTINGENT UPON PROPER APPLICATION, CORRECT INSTALLATION AND ADEQUATE MAINTENANCE. THIS INSTRUCTION BOOK MUST BE CAREFULLY READ AND FOLLOWED IN ORDER TO OBTAIN OPTIMUM PERFORMANCE FOR LONG USEFUL LIFE OF THE SELECTABLE GROUND AND TEST DEVICES.
Refer to Table 1.
THESE SELECTABLE GROUND AND TEST DEVICES ARE PERSONNEL PROTECTIVE DEVICES, AS SUCH, THEY ARE MAXIMUM RATED DEVICES. THEREFORE, THEY SHOULD NOT UNDER ANY CIRCUMSTANCES BE APPLIED OUTSIDE THEIR NAMEPLATE RATINGS.

SECTION 2: SAFE PRACTICES
Selectable Ground and Test Devices are designed with several built-in interlocks and safety features to provide safe and proper operating sequences.
DANGER
TO PROTECT THE PERSONNEL ASSOCIATED WITH INSTALLATION, OPERATION, AND MAINTENANCE OF THE SELECTABLE GROUND AND TEST DEVICES, THE FOLLOWING PRACTICES MUST BE FOLLOWED:
•
Only qualified persons, as defined in the National Electrical Safety Code, who are familiar with the installation and maintenance of medium voltage circuits and equipment, should be permitted to work on the selectable ground and test device.
•
Read these instructions carefully before attempting any installation, operation or maintenance of the selectable ground and test device.
•
Always remove the selectable ground and test device from the enclosure before performing any maintenance on the device. Failure to do so could result in electrical shock leading to death, severe personnel injury or property damage.
•
Do not leave the selectable ground and test device in an intermediate position in the cell. Always have the selectable ground and test device either in the DISCONNECT or CONNECTED position. Failure to do so could result in a flash over and possible death, personnel injury or property damage.
•
Keep all insulating surfaces, which include primary support insulation and insulation barriers, clean and dry.
•
Check all primary circuit connections to make certain they are clean and tight.
•
Take extreme care while using this device to avoid contacting “live” or “hot” (energized) terminals.
•
These selectable ground and test devices are equipped with safety interlocks. Do not defeat them. This may result in death, bodily injury or equipment damage.
•
Correctly identify LINE and BUS terminals for the breaker compartment before using this device. Remember that line connection may be on lower terminals when installed in upper compartment of 2-high switchgear.
•
Store the device in a clean, dry area free from dust, dirt, moisture, etc.
