Abstract: A method of determining if a circuit interrupter operating mechanism has an acceptable trip margin includes determining a model trip margin, providing a circuit interrupter, the circuit interrupter disposed in situ, the circuit interrupter including an operating mechanism, determining a circuit interrupter trip margin by: providing an internal sensor assembly, the internal trip margin sensor assembly structured to record trip margin data, providing a transfer function module, providing a computer structured to execute the transfer function module, executing the transfer function module on the computer, utilizing the trip margin sensor assembly to generate trip margin data, transmitting the trip margin data to the transfer function module, processing the trip margin data to generate a trip margin, and determining if the trip margin is acceptable relative to the model trip margin.
