Claim:
1. A component monitoring system structured to monitor operating mechanism component characteristics of a circuit breaker assembly, said circuit breaker assembly including an operating mechanism, said operating mechanism including a charging motor assembly, a first charging cam, a closing first spring, and a first spring cam follower, said charging motor assembly including a rotating output shaft, said first charging cam fixed to said motor assembly rotating output shaft, said first spring cam follower coupled to said closing first spring, said first charging cam operatively engaging said first spring cam follower, whereby rotation of said first charging cam compresses said closing first spring, said component monitoring system comprising: a record assembly including selected nominal data for a selected circuit breaker component; at least one sensor assembly structured to measure a number of actual component characteristics of said selected circuit breaker component and to transmit actual component characteristic output data; a comparison assembly structured to compare said sensor assembly actual component characteristic output data to said selected nominal data and to provide an indication of whether said sensor assembly actual component characteristic output data is acceptable when compared to the selected nominal data; said at least one sensor assembly in electronic communication with said comparison assembly; said record assembly includes data representing a selected nominal correlation coefficient of said selected circuit breaker component; said comparison assembly is structured to determine a correlation coefficient for said selected circuit breaker component by comparing a number of characteristics of the selected circuit breaker component and nominal data; and said comparison assembly is structured to compare said correlation coefficient to said selected nominal correlation coefficient and to provide an indication of whether said comparison of said correlation coefficient to said selected nominal correlation coefficient is within a selected range or outside said selected range.
