SECTION 2: SAFE PRACTICES

2-1 RECOMMENDATIONS

Type VCP-Wind 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
circuits and equipment, should be permitted to work on
these circuit breakers.
• Read these instructions carefully before attempting any
installation, operation or maintenance of these circuit
breakers.
• If the final breaker design is drawout, always remove
the breaker from the 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
secondary 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 TEST or DISCONNECT position
and follow all lock-out and tagging rules of the National
Electrical Code and any other applicable codes,
regulations and work rules.
WARNING
• Do not leave a drawout circuit breaker in an
intermediate 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 possible 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 equipment damage.
• Do not work on a circuit breaker suspended from a
lifting device or chains. Maintenance work should
be performed on a solid work surface, such as the
floor.
