A logging device for a trip unit records temporal information related to a circuit breaker trip event, with the circuit breaker (11) including a trip unit (12). The device (10) includes at least a clock circuit (13), a microcontroller (14), and a storage medium (15). The device (10) can be configured as either a plug-in module for the trip unit (12), or as an accessory is mounted on the panel proximate to and in communication with the trip unit (12). The clock circuit (13) generates signals representing temporal information, such as real-time date and time information. The microcontroller (14) is adapted to be coupled to the trip unit (12) to receive signals from the trip unit (12). These signals from the trip unit (12) indicate a circuit breaker trip event. The microcontroller (14) receives the time and date information from the clock circuit (13) and associates a given trip event with the time and date information related to that given trip event.

The present invention provides a plug-in ground fault monitor module for a circuit breaker trip unit configured to operate with a plurality of different plug-in plug-in modules. The ground fault monitor module includes a memory which stores data representative of the its particular function. This memory is readable by the trip unit and enables the trip unit to automatically adapt to communicate monitored ground fault data to the ground fault module. The ground fault module also includes means for setting threshold levels for a ground fault alarm signal. The ground fault alarm signal is generated independently of ground fault alarms in the trip unit based on its internal thresholds. This signal can be used to control an external relay which operates a shunt trip mechanism or an external alarm. The trip unit includes a processor and programming which permits a bi-directional flow of data between the units, such as display data and control data.
