SECTION 2: SAFE PRACTICES
2-1 RECOMMENDATIONS
Type VCP-W Vacuum Circuit Breakers are equipped
with high speed, high energy operating mechanisms.
They are designed with several built-in interlocks and
safety features to provide safe and proper operating
sequences. Cell interlocks used with drawout circuit
breakers are meant to interact with the appropriate cell
interface and levering mechanism.
TO PROTECT THE PERSONNEL ASSOCIATED WITH
INSTALLATION, OPERATION, AND MAINTENANCE
OF THESE CIRCUIT BREAKERS, 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 cir-
cuits and equipment, should be permitted to work on
these circuit breakers.
• Read these instructions carefully before attempting
any installation, operation or maintenance of these cir-
cuit breakers.
• Always remove the circuit breaker from its enclosure
before performing any maintenance. Failure to do so
could result in electrical shock leading to death,
severe personal injury or property damage.
• Do not work on a drawout circuit breaker with a sec-
ondary test coupler engaged. Failure to disconnect
the test coupler could result in an electrical shock
leading to death, personal injury or property damage.
• Do not work on a closed circuit breaker or a breaker
with closing springs charged. The closing springs
should be discharged and the main circuit contacts
open before working on the circuit breaker. Failure to
do so could result in cutting or crushing injuries.
• Do not use an open circuit breaker by itself as the sole
means of isolating a high voltage circuit. Remove the
circuit breaker to the Disconnect position and follow all
lock-out and tagging rules of the National Electrical
Code and any other applicable codes, regulations and
work rules.
• Do not leave a drawout circuit breaker in an intermedi-
ate position in the cell. Always have the circuit breaker
either in the Disconnect/Test or Connected position.
Failure to do so could result in a flash over and possi-
ble death, personal injury or property damage.
• Always remove the maintenance tool from the circuit
breaker after charging the closing springs.
• Circuit breakers are equipped with safety interlocks.
Do Not remove, interfere with or in any manner defeat
them. This may result in death, bodily injury or equip-
ment damage.
• Do not work on a circuit breaker suspended from a lift-
ing yoke or chains. Maintenance work should be per-
formed on a solid work surface, such as the floor.
