Overview Residual current devices (RCDs) are safety devices designed to switch off power in the event of a fault, acting as a trip switch. They offer safety levels beyond regular fuses and circuit breakers. RCDs are typically located in the fuse box or between the circuit breaker and power sockets.
Important Notice All our chargers require an RCD. If no RCD is installed, the warranty will be considered void.
If your Wallbox is not charging at all, the following steps can help you troubleshoot the issue.
Step 1: Unplug the Charger
Unplug the EV charger from the power source if the switch keeps tripping. This prevents further issues and ensures safety.
Step 2: Consider Other Appliances & Check the Circuit Load
- Refrigerators/Freezers: Initial power surges when cooling down may trip sensitive RCDs. This is usually temporary.
- Older Washing Machines/Dryers or Motors/Pumps: Worn-out components can develop insulation faults, causing leakage currents that trip the RCD.
- Central Heating Systems: Faults in systems involving water circulation or pumps can introduce leakage currents.
Step 3: Check the Charger’s Amperage
- Cause: Using a charger with an amperage rating higher than the circuit’s capacity can cause tripping.
- Solution: Ensure the EV charger’s amperage is compatible with the circuit. If necessary, adjust the charger’s power limit.
Step 4: Inspect for Faulty Cables
- Cause: Faulty appliances, including the EV charger, cable, or plug, can cause short circuits.
- Solution: Examine the charger, cable, and plug for visible damage or exposed wires. If any components are damaged, stop using the charger and contact support.
Step 5: Check for Water Exposure
- Cause: Water or moisture exposure can cause short circuits.
- Solution: Ensure the charger and outlet are dry. Do not use the charger until it is safe.
Step 6: Verify the RCD Current Rating
DISCLAIMER: This procedure should be conducted by a certified electrician.
- Cause: The RCD may not be appropriately matched to the load it’s protecting.
- Solution: Check the RCD’s current rating. If the EV charger draws more current than the RCD’s capacity, replace the RCD with one that matches the load.
Step 7: Assess RCD Quality
DISCLAIMER: This procedure should be conducted by a certified electrician.
- Cause: Low-quality or malfunctioning RCDs may trip unnecessarily.
- Solution: Replace old or low-quality RCDs with reliable, well-rated ones to ensure stable charging.
If the issue persists after following these steps, please contact a certified electrician or Wallbox support for further assistance.
