SURVEILLANCE REQUIRE >ENTS (Continued) c)
For each circuit breaker found inoperable during these functional tests, an additional representative sample of at least 10% of all the circuit breakers of the inoperable type shall also be functionally tested until no more failures are found or all circuit breakers of that type have been functionally tested.
2)
By selecting and functionally testing a representative sample of at least 10% of each type of lower voltage circuit breakers.
Circuit breakers selected for functional testing shall be selected on a rotating basis.
Testing of air circuit breakers shall consist of injecting a current with a value equal to 300% of the pickup of the long-time delay trip element and 130% of the pickup of the short-time delay trip element, and verifying that the circuit breaker operates within the time delay band width for that current sper.:ified by the manufacturer. The instantaneous element shall.
~
be Lested by injecting a current equal to 120% of the pickup value cf the element and verifying that the circuit breaker trips instantaneously with no intentional time delay.
Molded case circuit breakers and unitized starters (a frame size of 250 amps or less) shall be tested for long time delay at 300%
as described above, and in addition tested for the instantaneous trip by injection a current value which falls within +40% (of the upper limit) and -255 (of the lower limit) of the manufacturers instantaneous trip current range and verifying the breaker trips instantaneously with no intentional time delay.
1 l
For those molded case circuit breakers / unitized starters used in 480V circuits, if single pole instantaneous test results fall
(
outside these tolerances, additional intantaneous' testing shcil be conducted using two poles in series, including A-B, B-C and i
C-A phase combinations. All combination test results shall fall within the specified tolerances.
Circuit breakers found inoperable during functional testing shall be restored to OPERABLE status prior to resuming operation. For each circuit breaker found inoperable during these functional tests, an additional representative sample of f
at least 10% of all the circuit breakers of the inoperable type shall also be functionally tested until no more failures are l
found or all circuit breakers of that type have been l
l functionally tested.
b.
At least once per 60 months by subjecting each circuit breaker to an inspection and preventive maintenance in accordance with procedures prepared in conjunction with its manufacturer's recommendations.
