BrightGridAn EV charger that repeatedly trips electrical protection should not simply be reset again and again. The cause needs to be identified because repeated trips can indicate an electrical, equipment or installation problem.
Common causes
- Electrical protection issues
- Cable or connection problems
- Charger faults
- Vehicle charging faults
- Residual current protection operation
- Supply problems
- Excessive electrical load
Can household load cause problems?
A charger can represent a significant electrical load. Appropriate load management can help prevent excessive demand where the installation supports it.
What should you do?
- Stop repeatedly resetting the protection.
- Check whether the charger displays an error.
- Record when the trip occurs.
- Check whether the vehicle reports an error.
- Contact a suitably qualified installer or electrician.
Do not bypass electrical protection
Protective devices exist to help protect the electrical installation. A repeated trip should be investigated rather than bypassed.
Frequently asked questions
Why does my EV charger trip the fuse?
Possible causes include charger faults, vehicle faults, electrical protection issues, supply problems or excessive electrical demand.
Can I keep resetting my EV charger?
Repeated trips should be investigated rather than repeatedly reset. Contact an appropriately qualified professional if the problem persists.
