Lectron EV charger causes a GFCI or RCD breaker to trip when starting a charge, but the Lectron unit itself shows no error.

Safety first: Ground fault devices trip for safety. Do not bypass them without proper evaluation.

• 1. Dedicated circuit: Verify that the Lectron charger is on a dedicated circuit as recommended. Avoid sharing GFCI outlets with other loads.
• 2. Inspect receptacle (plug-in models): Check for moisture, corrosion, or heat damage at the outlet. Replace any suspect receptacle.
• 3. Test with another breaker: If allowed by code and manufacturer, use a standard breaker with the Lectron’s built-in ground fault protection instead of a GFCI breaker, following Lectron installation guidelines.

Resolution: If nuisance tripping continues on a proper dedicated circuit, have an electrician measure leakage current. If within Lectron specs, consider changing upstream protection per code. If leakage is high, the Lectron unit may have an internal fault and should be serviced or replaced.
