What to do when Tesla Charger is flashing red?

tesla wall connectorSo you finally have your Tesla charger installed and after some time you notice a flashing red light.

Red hardly ever means well, so you’re right to worry about it.

We’ve gathered the troubleshooting tips you need to handle this situation on your own or with a Tesla certified electrician.

If the light is a solid red

A solid red light on your Tesla charger could mean an internal fault and that the wall connector needs to be replaced. An electrician can confirm this. But your troubleshooting solution is to turn off the breaker supplying your Tesla charger with power and turn it back on.

If there’s no change and you still see the solid red light, contact Tesla with your product information.

If you see one red blink

One red blink on your Tesla charger could mean there’s a GFCI. Start your solution with an inspection of all the parts, including the handle, cable, Wall Connector, and vehicle charge port for damage or signs of water ingress.

Then, call an electrician to check that the ground wire is not directly connected to a conductor wire in the branch circuit.

If you see two red blinks

Two red blinks indicate a different problem from one red blink. It might mean there’s a ground assurance fault or possibly a high ground resistance has been detected.

Call an electrician to see if your charger is properly grounded or if any physical connections have such issues.

For three red blinks

This indicates a high temperature detected by your charger.

Inspect the physical parts of the wall connector, including the faceplate and cable, for warmth. Regardless of if you notice excessive warmth or not, call an electrician quickly to verify that the conductors used are sized correctly and there’s no danger from the connector.

For four red blinks

Thankfully, four red blinks just mean a disruption with the internet connection. Check for the cause of this interference. Like a changed password, working router, etc.

Fixing the reason should solve the problem.

For Five Red Blinks

If your Tesla charger is flashing red in five red blinks, it could mean there was a power-sharing communication issue. Hence, the charging speed has been reduced. Troubleshooting this is just like that of four red blinks, check for the interference, and try re-linking your wall connector.

When no lights come on

It’s not just flashing red lights you might have to worry about. An absence of light from your Tesla charger means there is no power supply coming in from the breaker panel.

Check if the breaker was turned off. Switch it on and off yourself and if there are no changes, call an electrician to check.

For Six Red Blinks

Flashing red lights 6 times means there’s too much voltage or poor grid quality detected. If you’re using the level 2 charger, the power supply should be nominal 200-240 volts. Have an electrician remove the Wall Connector from the wire box and confirm that voltage readings are correct.

For most problems with your wall connector, you can either reach out to Tesla or call an electrician to take a look.


Troubleshooting Your Tesla Wall Connector

tesla wiringAs reliable as your Tesla Wall Connector may seem, it’s not far-fetched for problems to come up. Sometimes these issues are easy to troubleshoot on your own. Other times, professional help may be needed. Here are some tips and troubleshooting solutions for your Tesla Wall Connector.

No lights on your Tesla Wall Connector

When you turn your Wall Connector on, the indication of power is the lights. If that doesn’t happen it means you have a power supply problem with no power coming from the breaker panel. This applies especially when your Wall Connector has been working fine before.

To solve this problem, check that the power supply is on. This needs a minimal knowledge of your breaker panel and how it works. It usually involves flipping a breaker back into the on position. If nothing changes, it’s likely time to call an electrician.

The electrician will remove the Wall Connector and check that there is voltage present and fix any issues with the breaker panel that may be the root cause.

The Wall Connector shows a solid red

If you have been using your Tesla Wall Connector for a while, seeing a solid red will stand out to you because the Wall Connector usually comes on with a green light. A solid red can mean a few things and none of them are good news. It could mean the Wall Connector is bad or has an internal fault. Either way, a repair or replacement becomes necessary.

What you can do to solve the situation is to first try turning off the circuit breaker. Wait for a few seconds after before turning it back on. If the solid red light persists, then it’s time to contact Tesla.

One red blink to seven red blink

A red blink code pauses for one second and then repeats itself. The good news is from one red blink to seven red blinks, your Wall Connector can give some indication of what problems need to be fixed.

One blink means there’s a GFCI interruption because of an unsafe current path. There might be damage somewhere.

Check the Wall Connector itself, the handle, cable, and vehicle charge port for signs of contact with water or damage. Call an electrician right after to fix the issue.

Two red blinks mean a ground assurance fault has been detected. Call a certified Tesla electrician to handle this. The electrical technician will have to see if the Wall Connector is properly grounded and check all physical connections alongside.

Three red blinks present a different problem, which is a rise in temperature. This can quickly become a fire hazard and should be attended to by an electrician as soon as possible. You can confirm the issue by checking if the faceplate and cable handle are warm to the touch.

In contrast to what you might be thinking, it doesn’t get worse with four red blinks. Four red blinks simply indicate lost internet connection, and you can check the Wi-Fi settings, router, and signal strength to handle this.

Five red blinks mean an issue with power-sharing communication and can be sorted the same as four red blinks.

Six and seven red blinks generally mean an overvoltage or poor grid quality and need either an electrician or Tesla’s assistance.

Tesla Wall Connector: Gen 2 VS Gen 3

Earlier this year, particularly January Tesla unveiled the 3rd generation wall connector. Since then everyone has been trying to know what’s good and what’s better with this new charger. If your Gen 2 Tesla charger is working just fine, why would you possibly be motivated to consider Gen 3?

We answer all the questions in this review below.

What’s Different?

Appearance. It’s almost the first thing you notice with this Gen 3 EV charger. The new electric charger’s fresh look comes as a glass front display on a white background, keeping the brand name font and color on its surface. In contrast, the Gen 2 Tesla EV charger has a plastic silver or black cover.

Power. The Gen 2 wall connector has always been a more powerful option, as it’s able to deliver up to 80 amps of power to your electric car. The Gen 3 however is limited to a maximum of 48 amps. But wait before you conclude, it’s important to remember that there are no electric vehicles – regardless of brand – that can charge at over 48 amps. Aside from this being Tesla’s way of sticking with the maximum power output, electricians can tell you that fewer amps mean less heat. Gen 2 electric chargers have often had overheating and sparking problems because of the heat.

Cable length. For the Gen 2, electric car owners can enjoy the flexibility of a 24 feet cable. This new Gen 3 charger falls short in this area with only 18 feet from Tesla. This can count as a significant disadvantage in most cases. Seeing as a standard 2-car garage in the United States is a 24’ by 24’ it’s vital to have a cable that can reach most corners.

Cable size. This will probably bring a smile to your face as Gen 2 users are all too familiar with the heavy and thick cable of Gen 2 electric chargers. With Gen 3 electric car charger the cable is lighter, thinner, and easier to manage. This also contributes to making the entire charger weigh less. It’s a good advantage from Tesla and one users will enjoy.

Wi-Fi. For all those who are tech-savvy and convenience-conscious, it’s wonderful to hear that the new Tesla charger is Wi-Fi enabled, and it allows you to connect the unit with your smartphone. But at the same time, some users have mentioned having no connection with their Gen 3 charger and app, while others say the smart charger can connect with the car. The use comes mainly by accessing the network with your computer to get updates and set up the charger. There is a strong possibility of more updates with the Wi-Fi from Tesla.

Load sharing. The former charging unit allowed load sharing with up to 4 connected units while the new Gen 3 allows load sharing for up to 16 devices wirelessly.

Cost. To our amazement, the cost of the Gen 3 electric car charger is the same $500 price as the older Gen 2 unit. It’s safe to assume that the various limitations on the Gen 3, when compared with Gen 2, helped cut cost and make this elite charger affordable.

What Size Breaker Does a Tesla Need?

tesla chargerHaving an electric car is great and very much a trendy decision. When you have the EV of your choice parked in your garage, the most important question that follows is what size breaker does a Tesla need. Your electric car may save on fuel but it needs electric power to work, and this starts with a suitable breaker size.

The most efficient charging option is a level two charge and this usually requires up to 50 amps circuit. Your electrician can provide an estimate for installing this, but there’s a high possibility it will involve upgrading your electrical service panel. Older homes often carry a 100 amps breaker, which may be sufficient for the average homeowner who has very few power-demanding appliances. Hence, a Tesla charger just won’t fit and an upgrade to a 200 amp panel would be necessary. Also, the electrician will have to run a line of 40 or 50 amps to the charging spot.

If you already have a 200 amp service all that is left is to install the new circuit and run a line to the spot the charger will be used.

While this is an ideal option, not everyone can handle the cost or hassle of a new service panel. When this happens, there are still ways around it to ensure you can get the charge you need. A level one charger is a basic part of every Tesla and it can be plugged into any dedicated outlet. This outlet can deliver on 12amps of power and that translates to 40 miles during an overnight charging session. If this isn’t sufficient for you, you may consider charging at work or in public places. However, if you need about 100 miles or more, you may have to use the ideal solution of upgrading your panel and using a level 2 charge.

There’s also an option known as the slow level two charge which allows you to use the 30 amp plug used for appliances like the dryer. This allows the car to charge at 24 amps overnight. Bear in mind that the average Tesla can’t take over 32 amps, which is a 40 amps circuit in the first place. The 24 amps will give between 17-22 mph on Tesla models.

To make this work conveniently you can switch to a natural gas dryer. Yes, it will cost you, but the price might be more comfortable than a service panel upgrade. This way you can conveniently use that 30 amp plug for your Tesla.

If you can’t decide on what’s best, reach out to us for further consultation. Our professional and experienced Los Angeles electricians will help you with the most suitable options.


How many amps is a Tesla charger?

Electric cars are clearly the latest and most sought after development in the automotive industry and Tesla is leading the pack. So, when you have just purchased your very own green car, you can leap for joy about avoiding fueling costs and several other issues that come with it.

However, you still have to figure out charging your Tesla.

The amperage of your Tesla charger can play a vital role in determining how much total charge or miles of driving you get. Here’s the breakdown of amps per charger level.

You might be familiar with using a level one charger, which is the common 120V outlet in your home. This works with the portable EVSE (UMC) that comes with the car and gives an amperage of 15-20 amps. As far as miles go, you will replenish 3-4 miles per hour. While the charge time may be slow, this works fine for many Tesla drivers.

The level 2 charge is a 240V outlet installed by a professional electrician as a dedicated home EVSE. It has the capacity to power tough power-hungry machines like your dryer. This charge is more powerful than the previous option and delivers on up to 80 amps. This translates to anywhere between 9-52 miles of Tesla range per hour charging.

Level 3 charge, which is hardly an option for homes and private buildings, is an ultra-fast, ultra high-power 480V circuit. They are superchargers often found at charging stations and account for why it’s sometimes faster to use a public charging station than a home charger. It delivers on up to 300 amps, which is up to 170 miles per hour of Tesla charging.

When you look at the spread, you find that you do have a few suitable options. What you choose depends on your driving habits and miles. To install a level 2 charge be sure to contact a professional electrician or Tesla charger installer.

Installing EV Charging Types

  • Level 1
  • The voltage for the Level 1 charger type is 120V. The average charging time is 10 to 20 hours. No equipment is required to install a level 1 charging type. You simply plug into the 120V in your home to use this charging type.

  • Level 2
  • The voltage for the Level 2 charger type is 240V and the average charging time is 4 to 8 hours. It can be installed in your home or building by a qualified electrician. You would need an electric vehicle charging station and a dedicated circuit from your panel.

  • Level 3
  • A level 3 charger uses 480V. It has the fastest charging time of 20 to 30 minutes. It usually requires a separate plug and is available mostly in retail settings. It is perfectly suited for public charging.

To install an electric vehicle charger in Glendale, the installer would need a permit.

It’s important to note that charging time may differ slightly from the figures above depend on the make of your car and its battery size. When installing the charger types, your circuit breaker should have the capacity to handle their power needs to avoid tripping. Home installations are necessary for convenience and achieving a full charge most of the time.

Electric vehicles come in different models, make, and design. Some might help you save better than others. The factors that influence how much you would spend on your electric vehicle include the cost of electricity, make and model of the car, driving conditions, and more.

What is the Difference Between AC and DC?

ac dc voltageElectricity is almost as important as oxygen nowadays. It powers everything around us in one way or the other. Just like electricity is useful, it can also be dangerous. But we will not discuss the dangers here.

Electric current flows in either of two ways–AC or DC. For years, these two types of current have been compared to decide who is king, but it has been a tough battle. What really is the difference between AC and DC? Read on to find out.

AC which is Alternating Current was developed by Nikola Tesla. It is a current that switches direction; sometimes going backwards or forwards. It is represented by a wave-like current. DC is Direct current developed by Thomas Edison and it flows in a steady single or forward direction. For AC the cause of its switching direction is a rotating magnet along the wire. This is unlike DC which has steady magnetism along the wire to give it a forward direction.

AC is better suited for traveling longer distances and it provides more power. DC, on the other hand, would lose its energy over long distances and is preferable for shorter distances.

In a circuit, DC flows in one direction while AC reverses its direction.

How the differences between AC and DC are applied

AC is most commonly applied in the home or in offices. Transformers are used to aid the change in voltage from high to low. AC current is used up by home appliances like your TV, Air conditioner and more.

DC supplies electric current to electric devices that use a battery. A good example is your mobile phone or radios. A laptop uses both AC and DC currents. AC current flows from the circuit through the charger to the box in the middle. This box known as a power adapter converts the AC current to DC.

AC and DC remain widely used for different purposes in the electrical industry.

A Funny Rivalry

History has it that in the 19th century, Edison and the Westinghouse had a sort of war over which current was superior. Apparently, Edison had patents invested in the wide use of DC and he did not take kindly to the competition with AC. Edison decided to prove that DC was superior with demonstrations of AC killing large animals. For that time, his experiments to show that AC was dangerous caused many to turn to DC. But soon the limitations of DC were discovered and AC became dominant.

What Size Wire For Tesla Charger

tesla wiringWhen you are obsessed with pretty cars and tired of driving fuel powered vehicles, then an electric vehicle like Tesla is your best bet. A lot of drivers want to get behind a Tesla vehicle just to enjoy the thrill of riding such a car.

With Tesla, you never have much to worry about, except, of course, charging. Charging electric vehicles can be smooth and easy depending on your choices. Tesla makes things even better with its superfast chargers and convenient charging options.

Now, you know you can charge your EV at home using either the 120V outlet or the 240V outlet. 120V gives you a slow trickle charge and might limit your full experience with your sweet vehicle. The 240V outlet, on the other hand, is every driver’s delight. You can get a full charge in a few hours and maximize your Tesla experience.

Installing the Tesla wall charger at home

The first thing to note is you need an experienced electrician to install your Tesla wall charger. While it is important to have some basic knowledge to help you make informed decisions, it is not advisable to take on the full installation yourself.

The wall charger will comprise a connection between the breaker and the outlet or wall connector. This will involve a run of wire and for Tesla chargers, you do not need just about any wire. Generally, EV charging should be installed using copper wires because most aluminum wires are not rated for EV use. Aluminum wires are also known to overheat frequently which can be dangerous for your car and home.

Tesla wall connectors are rated for only copper wires.

Ensure the wire you choose has current handling abilities and resistance. Depending on your needs and connection made by the electrician, your wire size needs may vary. They can be any size between 3AWG and 8AWG. Ensure you discuss what is needed with the electrician and allow them to purchase the materials themselves.

At The Electric Connection, we provide free estimates on your installation and a complete EV charger installation service. We know what you need and will discuss your options with you. Contact us for a dependable charging system that lets you enjoy your Tesla.

Can Electric Vehicles Use HOV Lanes?

los angeles ev charger installationHigh-occupancy vehicle lane which is popularly known as HOV lanes is a traffic lane restricted and reserved for use by vehicles with a driver and one or more passengers. The minimum number of occupants is 2 to 3. In simple terms, the aim of this traffic lane is to get as many people off the road as possible to reduce traffic and air pollution.

There are over 126 HOV facilities across the United States. These lanes are not as effective as intended on most days, but they remain in use. They do help to save time during traffic congestion.

The principles behind HOV lanes exempt certain cars from using them. These vehicles include motorcycles, law enforcement vehicles, charter buses, some low emission vehicles and single occupancy vehicles paying a toll. The vehicles allowed on high-occupancy vehicle lanes are battery electric vehicle (BEV), fuel cell vehicles (FCV), and carpool, vanpool, and transit buses.

Electric vehicles are becoming more popular by the day. In most jurisdictions, they are allowed on HOV lanes. The benefits of this for drivers are:

  • Spend less time in traffic
    Fuel run vehicles have the ability to withstand traffic congestion, but this is different for electric cars. The stop-and-go traffic routine would reduce the car’s batteries. Hence, it helps for electric car drivers to be included in the use of HOV lanes.
  • Promoting clean air and cars
    It’s no secret that electric cars emit no harmful gases. They are unique for their contribution to clean air and clean cars. Using HOV lanes is a perfect way to advertise the concept of electric cars to others. It is an effective way of stating the importance of electric cars.

To use the High-occupancy vehicle lanes, electric vehicle owners have to get a permit from the Department of Motor Vehicles. They would be given a sticker which is usually placed on the rear bumpers and rear fenders.
