SURVEILLANCE REQUIREMENTS 4.8.4.2 The overcurrent protective devices shall be demonstrated OPERABLE at least once per 18 months by selecting and testing one-half of each type of circuit breaker on a rotating basis.
Testing of these circuit breakers shall consist of injecting currents in excess of the breaker's nominal setpoint and measuring the response time of the long time and short time delay elemen+.s and the setpoint of the instantaneous element, as appropriate.
The measured data shall be compared to the manufacturer's data to ensure that it is less j
