Claims

[Scope of Claim for Utility Model Registration] (1) An electronic circuit that is housed in a housing and has a built-in time recognition means, a pickup means that picks up a ground fault current flowing in the earth circuit of the housing or the electronic circuit, and and a recording means for recording the time based on the time recognition means when the pick-up means detects that a ground fault current has flowed through the earth circuit. Electronic equipment with. (2) The earth fault current according to claim 1, wherein the recording means records the current value of the earth fault current at the same time as recording the time based on the output of the pickup means. An electronic device that has a history recording means.
