SECTION 2: SAFE PRACTICES
W-VAC, W-VACR, and W-VACW breakers are
equipped with high speed, high energy operating mech-
anisms. They are designed with several built-in inter-
locks and safety features to provide safe and proper
operating sequences.
• Do not work on a breaker with the secondary test cou-
pler engaged or fixed secondary connections made.
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 breaker or a breaker with
closing springs charged. The closing spring should be
discharged and the main contacts open before working
on the breaker. Failure to do so could result in cutting or
crushing injuries.
TO PROTECT THE PERSONNEL ASSOCIATED WITH
INSTALLATION, OPERATION, AND MAINTENANCE
OF THESE BREAKERS, THE FOLLOWING PRAC-
TICES MUST BE FOLLOWED:
• Only qualified persons, as defined in the local electri-
cal code who are familiar with the installation and main-
tenance of medium voltage circuits and equipment,
should be permitted to work on these breakers.
• Read these instructions carefully before attempting
any installation, operation or maintenance of these
breakers.
• Always remove the removable breakers from their
enclosures or disconnect the fixed primary connections
associated with fixed breakers before performing any
maintenance. Failure to do so could result in electrical
shock leading to death, severe personal injury or prop-
erty damage.
• Do not use a drawout circuit breaker by itself as the
sole means of isolating a high voltage circuit, Remove
the breaker to the Disconnect position and follow good
lock-out and tagging rules, as well as all applicable
codes, regulations and work rules.
• Do not leave a drawout breaker in an intermediate
position in the cell. Always have the breaker either in the
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 breaker
after charging the closing springs.
• Circuit breaker elements 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.
