Troubleshooting

My EV charger trips the breaker as soon as I plug it in

Home Nura guide — category: Home EV Chargers

Severity: critical

Diagnosis

Warning: this symptom can point to a serious hardware defect. Stop using the device until the cause is found. We recommend contacting the manufacturer or an authorized repair centre before you try to use it again.

Recommended steps

Unplug it right away and stop using the device. Document the symptom (photos, video, sounds), then contact the manufacturer's support. If the device is still under warranty, keep your proof of purchase handy: this kind of failure is exactly what the warranty is for.

Repair or replace?

If the problem persists after these checks and the appliance is no longer under warranty, compare the repair estimate with the cost of a new model.

Frequently asked questions

Usually, yes, if the failure shows up during the warranty period and isn't caused by misuse. A product in the Home EV Chargers category bought new from an authorized retailer normally comes with a manufacturer's warranty: check its length in the manual or on the brand's website. Consumer protection rules also vary by province and territory, so keep your proof of purchase.

If you're still within the store's return window, a return or exchange is usually the fastest fix. After that, the manufacturer's warranty takes over: its customer support can arrange a repair or a replacement. Even outside the warranty, the manufacturer can often repair the device for a fee. Either way, keep your proof of purchase.

Our public methodology lowers the Nura Score /10 of any model in the Home EV Chargers category whose recurring failures are documented in owner reviews. A model that breaks down too often never tops our rankings, whatever the brand.

Generally, yes. Routine maintenance, such as cleaning, replacing a gasket or recalibrating, is part of normal use and doesn't usually affect your warranty. Irreversible changes to the hardware are what can cause problems. For a product in the Home EV Chargers category, stick to the steps described in the manufacturer's manual and read the warranty terms before going any further.

When a product fails in its first few months of normal use, the cause is usually a manufacturing defect. Contact the seller or the manufacturer with your proof of purchase and a description of the symptom: for a model in the Home EV Chargers category that is still under warranty, this is the typical case for a free repair or replacement. Warranty terms vary by brand, so read yours.
