Possible Causes

Upstream RCD/GFCI too sensitive for EVSE load, Combined GFCI in panel and in Megear charger causing interaction, Slight leakage current from cable capacitance, Weak or aged breaker

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker without investigating. Frequent tripping can indicate a real fault.

  • 1. Isolate loads:
    • Ensure the Megear charger is on a dedicated circuit with no other large loads.
  • 2. Check for dual GFCI:
    • If the circuit uses a GFCI breaker and the Megear has built-in GFCI, consult an electrician about using a standard breaker instead, as dual protection can cause nuisance trips.
  • 3. Inspect cable and connector:
    • Look for damage or moisture that could increase leakage.
  • 4. Breaker health:
    • Have an electrician test or replace an older or frequently tripping breaker.

If tripping persists after these steps, have the charger insulation and leakage current tested by a qualified technician.
