SECTION 2: SAFE PRACTICES
The circuit breakers are equipped with high speed,
high energy operating mechanisms. They are
designed with built-in safety interlocks to provide for
safe operation. In addition, other optional interlocks
are available depending upon the application. Refer to
Section 5 for additional interlock information. It is the
customers’ responsibility to insure that appropriate
interfaces with the breakers are provided and tests
conducted to adequately prove proper installation and
functioning.
Always make sure that primary and secondary
power are disconnected from a fixed breaker
before performing any maintenance. Failure to do
so could result in electrical shock leading to death,
severe personal injury and/or property damage.
Do not work on a closed breaker or a breaker with
closing springs charged. The closing springs
should be discharged and the main contacts open
before working on the breaker. Failure to do so
could result in cutting or crushing injuries.
Do not use a circuit breaker by itself as the sole
means of isolating a high voltage circuit. As
appropriate, use an isolation means and follow all
lock-out and tagging rules of the Local Electrical
Codes and any and all applicable codes,
regulations and work rules.
Always ensure that drawout circuit breakers are in
one of their designed cell positions, such as
Connect, Test/Disconnect or Remove. A circuit
breaker permitted to remain in an intermediate
position could result in control circuits being
improperly connected resulting in electrical failures.
Breakers are equipped with safety interlocks. Do
Not defeat them. This may result in death, bodily
injury and/or equipment damage.
Do not work on a circuit breaker while
suspended from a lifting means. Maintenance
work should be performed on a properly
supported cart or table.
WARNING
TO PROTECT THE PERSONNEL ASSOCIATED
WITH INSTALLATION, OPERATION, AND
MAINTENANCE OF THESE BREAKERS, THE
FOLLOWING PRACTICES MUST BE FOLLOWED:
Only qualified persons, as defined in the Local
Electrical Codes, who are familiar with the
installation and maintenance 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 drawout type breakers from their
enclosure before performing any maintenance.
Failure to do so could result in electrical shock
leading to death, severe personal injury and/or
property damage.
