Confirm which loop or circuit the panel is flagging, then disconnect it at the panel — if the fault clears, the problem is in the field wiring or a device, not the panel. Test the disconnected cable with an insulation-resistance tester, conductor-to-earth on each core, then split the circuit at convenient points (isolators, junction boxes) and re-test each half to close in on the fault. Damp devices, crushed cable, and screws through hidden runs are the usual culprits. Record the readings, not just "fault cleared" — the megger values are your evidence. Standards are referenced for orientation only — always confirm requirements against the current edition of the applicable standard, the site's fire strategy and manufacturer documentation.
