Possible Causes
Combined RCD sensitivity with internal DC leakage detection, Shared RCD with other loads, Inrush current exceeding breaker characteristics, Minor insulation leakage in cable or EV
How to Fix / Troubleshooting
Safety first: Frequent tripping may indicate a real fault. Do not simply replace breakers with larger ones without assessment.
- Dedicated circuit: Confirm the Webasto charger is on its own dedicated breaker and RCD as recommended by the installation manual.
- Breaker type: Ask an electrician to verify that the breaker and RCD types (B, A, F, etc.) are compatible with EV charging loads.
- Inspect cable and EV: Look for visible damage to the cable and test with another EV if possible to isolate the source.
- Measure leakage: A professional can measure earth leakage and inrush current and adjust protection devices or replace marginal components accordingly.
