FAULTY BATTERY CHARGER tripping the yard's GFCI? | Ask The Expert with NIGEL CALDER

What this video covers

A battery charger with minor internal leakage current trips a 5mA ground fault circuit interrupter (GFCI) when connected to a 125-volt yard outlet via an adapter.0:28 This nuisance tripping occurs because the GFCI has a low sensitivity threshold designed to detect small current imbalances.1:02 The same charger functions normally at older marina pedestals that lack ground fault protection, but it would likely trip modern pedestals equipped with 30mA residual current devices (RCDs) if the leakage exceeds that limit.1:02 The charger’s internal components have degraded over its eight-year service life, causing the fault.0:16 Replacing the faulty battery charger resolves the issue and eliminates the leakage current.1:52
