Possible Causes
Inrush current exceeding breaker tolerance, Combined leakage current exceeding RCD rating, Shared RCD with other loads, Incorrect breaker or RCD type for EV charging
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a tripping breaker or RCD without identifying the cause. Risk of fire or shock.
- Check breaker/RCD ratings: Verify that the upstream protection devices match Schneider's recommendations for your EVlink model (e.g., type A or B RCD, C-curve breaker).
- Dedicated circuit: Ensure the charger is on a dedicated circuit and not sharing an RCD with other high-leakage appliances.
- Test with reduced current: If possible, lower the charger's maximum current setting and see if trips stop. This can indicate marginal wiring or breaker sizing.
- Insulation and leakage tests: Have an electrician perform insulation resistance and leakage current measurements on the charger and circuit.
- Upgrade protection: If necessary, install appropriately rated Schneider Electric breakers/RCDs dedicated to the EVlink charger.
