How To Troubleshoot Tesla Model 3 Charger Tripping Breaker Issues?

If you’re experiencing issues with your Tesla Model 3 charger tripping the breaker, you’re not crazy. This issue is seen by many Tesla owners while charging at home.

Whether you’re using a dedicated Tesla wall connector or a standard charging outlet, a tripping breaker can disrupt your charging sessions and leave you frustrated.

Let’s start with how to troubleshoot Tesla Model 3 charger tripping breaker problems, covering everything from common causes to simple fixes.

Why does the breaker keep tripping the Tesla charger?

The breaker keeps tripping your Tesla charger for several reasons:

Charger Malfunction: Internal faults in the charger can trigger breaker trips.

Overcurrent Protection: The charger may be drawing more amps than the breaker can handle. For example, a 50-amp breaker might trip if the charger exceeds 50 amps.

Improper Circuit Breaker Size: Using a breaker that’s too small for the charger’s requirements can cause frequent trips. Tesla recommends a 60-amp breaker with 6 AWG copper wire.

Loose Wiring Connections: Poor or loose wiring can cause electrical resistance, leading to overheating and breaker trips.

Overheating: Extended charging at maximum capacity (e.g., 48 amps) can overheat the breaker, triggering it to trip.

Ground Fault: A ground fault in the charger or wiring can cause the breaker to trip for safety.

Inrush Current: The initial surge of current when plugging in the charger can sometimes trip the breaker if it’s not rated to handle it.

Troubleshooting Tesla Model 3 Charger for Tripping

Check Breaker Size: Your Tesla Model 3 charger needs a 60-amp breaker. If you’re using a smaller one, upgrade it to a 60-amp breaker with 6 AWG copper wire.

Inspect Wiring: Look for any loose or damaged wires, especially where the charger is connected to the electrical panel. Tighten loose connections and replace any faulty wiring.

Verify Charging Load: Ensure the charger isn’t set to a higher amperage than your breaker can handle. If you’re charging at 48 amps, you need a 60-amp breaker.

Test the Breaker: If the breaker trips consistently, it could be faulty. Try resetting it, or replace it if it keeps tripping.

Check Grounding: Ensure the charger is properly grounded. A grounding issue can cause the breaker to trip for safety.

Monitor Inrush Current: When you first plug in the charger, there might be a surge in current that can trip the breaker. If this happens often, your breaker may not be rated for the initial inrush current.

Inspect the Charger: If all else looks fine, check the Tesla Model 3 charger for faults. A malfunction within the charger can cause the breaker to trip.

How do you reset a Tesla Model 3 charger?

To reset any Tesla charger for your Model 3, follow these steps depending on the charger type:

1. Tesla Wall Connector

• Unplug the charger: Disconnect the Tesla Wall Connector from the car.
• Turn off the power: Go to your electrical panel and switch off the breaker that supplies power to the Wall Connector.
• Wait for 30 seconds: Give the charger time to reset.
• Turn the power back on: Switch the breaker back on.
• Plug the car back in: Reconnect the charger to your Tesla Model 3 and check if it’s charging properly.

2. Tesla Mobile Connector (Portable Charger)

• Unplug the charger: Disconnect it from the car and the outlet.
• Reset the outlet: If you’re using a GFCI outlet, reset it by pressing the reset button on the outlet itself.
• Wait for 10 seconds: Let the charger sit idle for a few seconds.
• Reconnect: Plug the charger back into the outlet, then reconnect it to your Model 3.

3. Supercharger (Tesla Charging Stations)

• Move to another stall: If the charger is malfunctioning, try moving to a different Supercharger stall.
• Notify Tesla support: If switching stalls doesn’t help, contact Tesla support to check for any issues at the Supercharger station.

Soft & Hard Reset of Tesla Model 3 Charger

🔌 Tesla Wall Connector (Gen 3)

Soft Reset:

1. Power Cycle: Turn off the circuit breaker supplying power to the Wall Connector. Wait for 5 seconds, then turn it back on. This can resolve minor issues and reset the unit. ​

Factory Reset:

1. Initiate Wi-Fi Broadcasting: Press and hold the button on the Wall Connector’s charging handle for 5 seconds. This action prompts the unit to broadcast its Wi-Fi network (SSID) for 15 minutes.
2. Connect to Wi-Fi: On your mobile device, connect to the Wall Connector’s Wi-Fi network using the password found in the Quickstart Guide.
3. Access Configuration Page: Open a web browser and navigate to http://192.168.92.1.
4. Reconfigure Settings: Follow the on-screen instructions to reconnect the Wall Connector to your home Wi-Fi network and adjust settings as needed.​

🔌 Tesla Mobile Connector (Gen 2)

Soft Reset:

1. Unplug and Replug: Disconnect the Mobile Connector from both the vehicle and the power outlet. Wait for a few seconds, then reconnect. This can reset the unit and resolve minor issues. ​

Hard Reset:

1. Locate Reset Button: Find the small reset button on the Mobile Connector.
2. Press and Hold: Press and hold the reset button for 5 seconds, then release. This can help clear persistent faults. ​

Note: If the Mobile Connector continues to malfunction after these resets, it may be faulty and require replacement.

How To Prevent Tesla Charger From Tripping?

Avoid Extension Cords: Never use an extension cord for Tesla vehicle charging. These cords are not designed to carry heavy currents and can pose a potential fire hazard.

• Minimize Appliance Use While Charging: Turn off or unplug other appliances on the same circuit as of your Tesla Wall charger to pull down the load connected.

• Standard Outlet with Dedicated Circuit (Preferred): The Tesla adapter can be matched to NEMA 5-15 or NEMA 14-50, which have a 20 ampere or more circuit breaker. Install the system so that it must not be interconnected to the Tesla two-way GFI system and be free from overloading if shut off. 

• Consider a High-Power Wall Connector: If you love faster charging speeds for your Tesla Model 3 and a dedicated circuit, you may choose a  Tesla Wall Connector.

A professional installer should only install this to ensure it meets safety compliance and your home’s electrical power (kWh) and adheres to local electrical code.

FAQs: Tesla Charger Issues

Why does my Tesla charger trip the breaker on 110V?

110V outlets are insufficient for Tesla charging. The charger requires higher voltage (240V) for proper charging. Upgrade to a 240V outlet for safe charging.

Why does Tesla mobile charger trip the GFCI?

A Ground Fault Circuit Interrupter (GFCI) may trip due to a fault in the charging cable, improper grounding, or moisture. Check the cable, connections, and ensure proper grounding.

What to do if my Tesla charger causes a short circuit?

Immediately stop using the charger, disconnect it from the power source, and inspect the wiring for damage. If the issue persists, contact Tesla support or an electrician for further inspection.
