Tesla Charger Keeps Tripping Breaker [9 Ways to Fix]

Nothing is more convenient than having a Tesla wall charger at your home. That saves you time for charging your Tesla at a charging station when you are in a hurry. 

But the Tesla charger keeps tripping breaker, which is annoying, especially when you are unfamiliar with the cause and method to solve the problem.

My brother faced this problem, so I’ll explain how I helped him troubleshoot the issue in this guide. 

Why Tesla Charger Keeps Tripping Breaker

Tesla Charger Keeps Tripping Breaker

Here are a few common reasons why the Tesla charger keeps tripping.

You probably do not know, but I’ll explain easily so you can implement the fixes to resolve the problem.

1. Circuit Overload

Circuit overload happens when an abnormally high power amp passes through the circuit. 

It’s a hazardous situation, and breakers connected to the Tesla wall charger are meant to fight it—breaker trips to save you from getting an electric shock and saving the risk of injury. 

Remember that it only happens when the Tesla charger and many high-powered appliances share the same circuit.

Alternatively, the live wire accidentally comes in contact with the neutral wire, and the breaker keeps tripping.

2. Short Circuit

You might not have noticed, but the charger’s connectors get loose or damaged with time, and the electricity tends to flow in the alternative unintended path.

That situation is life-threatening and may start a fire in the circuit.

So, the breaker connected to your Tesla charger keeps tripping to short circuits, which is the biggest reason for structural fires globally.

3. Ground Fault

Suppose the water leaking to the Tesla charger can cause a ground fault. Also, the poorly connected appliances to the circuit can cause it. 

Your Tesla charger circuit may have come in contact with moisture, or the wires have connected with the ground wire.

That was where the breaker trips to prevent the massive house fire and trips to stop the electricity flow.

4. Incompatible Breaker 

Not all the breakers need to be compatible with the panel. Many breaker brands are interchangeable, but only a few are incompatible. 

So, there is a fair chance that the Tesla breaker is tripping as it’s incompatible, and you need to seek the help of an electrician to find that out.

5. Poor or Damaged Wiring

A short circuit or ground fault is also why your wiring is damaged or poorly connected. Another factor also damages the wiring and exposes the circuit to potential damage.

The rodents often chew the wire, which results in a short circuit. 

Alternatively, the wires are poorly connected, raising the danger of sparking and arcing. So, your Tesla charger’s breaker will keep tripping to save the circuit from a potential fire and explosion hazard. 

6. Faulty Breaker

Lastly, you may want to check if the breaker is burnt. The breaker provides a significant thermal contribution. Chances are, it wears out after some time.

You may want to test the breaker with the help of a multimeter. If no voltage is indicated, you need to replace the breaker. 

But I would suggest replacing the breaker if it’s used for quite some time because it gets weaker after a certain period.

So, to save yourself from any issue, get rid of a burnt or weak breaker.

How to Fix A Tesla Charger That Keeps Tripping

1. Authenticate The EV Energy App

The EV energy app connects directly with your EV charger and Tesla. You can set a time limit, and it will charge the Tesla using the cheapest and greenest energy using the Tesla home charging set.

You can start using the app using the Tesla account login. It will contain all the charging history of the kWh that was delivered to your car.

In this way, you can know the watts your car received when the breaker tripped in the last charging session. That will help you diagnose the problem.

2. Check For A Short Circuit

If your Tesla charger keeps tripping, the other appropriate action is thoroughly checking the wires and charger for any visible damage or burn.

These are the common culprits of a circuit breaker tripping repeatedly.

You must check the other appliances using the same power source. As a first step, you have to connect the appliances to a separate circuit breaker. 

That will reduce the electrical overload over a circuit breaker in this way. Now, you can charge your Tesla using the wall charger and see if the problem is resolved.

3. Replace A Faulty Breaker

The light will begin flickering if it is connected to the same circuit breaker as the Tesla charger.

On the other hand, if the circuit breaker trips as soon as you connect the charger, it indicates that you need to replace the circuit breaker. 

Make sure to attach a suitable circuit breaker this time that can do tripping current level adjustments for overload protection in case of any short circuit. 

Also, buy a breaker that is compatible with the panel.

4. Call A Pro to Trace Out An Earth Fault

If a water pipe has leaked in the wall, and the circuit has a damaged wiring connection. The electricity will jump out of the circuit after coming in contact with water as water is a good conductor.

Hence, the spike will result in the breaker trip. So, if you know of a water leakage, don’t handle the wiring and connectors yourself and call a professional electrician

They will trace the earth fault, change the wet wire breaker, and clear the circuit from the earth fault. They will locate and fix the water source, too, to avoid any problems in the future.

5. Check The Wiring Is Appropriate

Most old houses use 30 amps electrical service, which charges the Tesla exceptionally slowly. If you install the Tesla wall charger at home, the wiring appropriately handles 60 Amp electricity flow. 

It will take less time to fully charge the Tesla, and the wiring will not overheat when you charge your Tesla.

Afterward, check the loose connectors with the charging cable and tighten the screws on the terminal. The loose connectors are the common reason for a tripping breaker.

6. Use the Right Charger Adapter

The right charger adapter is necessary to prevent the frequent tripping of your circuit breaker.

The one charging adapter that uses the 10-50 amp to charge will handle the current flow in the circuit if appropriate. 

Make sure to buy the right charging adapter for your Electrical vehicle. Change the existing one if there are visible signs of burn on the charging adapter.

7. Power Cycle Wall Charger

You can perform a power cycle if you cannot trace a visible fault in the electrical circuit where the Tesla is connected. The power cycle will be an effective way to remove any fault in the circuit of your wall charger.

You need to turn the breaker off for 10 minutes. At that time, the residual electricity will drain. Turn the breaker back on after 10 minutes.

You will see the flickering green light over the charger, indicating that the charger is connected and charging your Tesla.

8. Install Firmware Update

A software bug may prevent the Tesla from charging. Hence, you must install the latest software version to troubleshoot any faults.

  • To do this, you must access the Tesla touchscreen and tap the car icon in the lower left corner.
  • Then, Navigate the ‘Software’ and tap on the ‘Update’ to install the available update in your Tesla.

9. Reduce The Charging Rate

You can reduce the charging rate at which your Tesla charges. Chances are your wiring and breaker do not support a relatively fast charging rate. 

Ensure to reduce the charging rate to prevent any interruption in the Tesla charging process.

Why Does My Tesla Charger Keeps Tripping The Outlet?

Tesla charger keeps tripping due to bad wiring, loose connectors, a leaked water source in the same wall, or a firmware bug.

You need to diagnose the problem to remove any fault in the Tesla circuit.

What AMP Breaker Do I Need For A Tesla Charger?

A 50 amp breaker is suitable for a Tesla home charger, which gives 26 amps at 240 volts. You can also manually restrict the charger by limiting the supply to 28 amps. 

How Do You Reset A Tesla Wall Charger?

  1. You can reset a Tesla charger by turning the breaker off for 10 minutes.
  2. Then, turn it back on and connect the Tesla wall charger to the car.
  3. A blinking green light shows that the wall charger is charging Tesla.

Can A Tesla Wall Charger Be Repaired?

Many electricians offer to repair Tesla wall chargers, which is possible, but Tesla discourages disassembling, repairing, and modifying a wall charger.

Conclusion

Being able to charge Tesla at home is a great facility. It cuts the cost of charging at the supercharger, but at the same time, you need to ensure that wiring, connectors, and breakers are compatible.

I hope the guide helped you fix the breaker issue connected to your Tesla wall charger. However, consult a professional electrician if you suspect a short circuit or ground fault.
