NEMA 14-50 Outlet Installation Cost

Whether you’ve just received your electric vehicle (EV), planning to buy one soon, or have had your EV for some time, you’ll need to figure out how you will charge your car at home. Charging with a Level 1 charger, which is included in every EV purchase or lease, is not efficient and you are often left without enough of a charge or having to deal with range anxiety. On the other hand, relying solely on public charging stations is impractical and extremely inconvenient.

To get a Level 2 home charger you will need an electrician to install a NEMA 14-50 outlet or have it hardwired. How much does a NEMA 14-50 outlet installation cost and can any electrician install a NEMA 14 50 outlet for EV charging? We answer those questions for you in this quick read!

Why do you need to install a NEMA 14-50 outlet for an EV charger?

A NEMA 14-50 outlet is for a plug-in Level 2 charger. In a hardwired installation, the conduit is run from the electrical panel directly into the charger. In a plug-in installation, the conduit is run from the subpanel to a NEMA 14 50 outlet.

A plug-in EV charger is convenient because it can be unplugged and taken with you when you move. But it is also more expensive to install than a hardwired charger.

Some electric utilities will only provide a rebate when the EV charger is hardwired, so it’s important to do your research and find out what gives you the best bang for your buck. In general, hardwired EV chargers are less expensive to install than plug-in chargers, and they’re also more efficient and durable. If you’re not sure what type of charger is right for you, it’s always a good idea to consult with an EV expert.

A Level 2 home electric car charging station needs more electrical power than your standard home 120-volt outlet – it requires a 240 volt outlet. You are probably familiar with this type of outlet since it is the same type used for your electric clothes dryer or range oven. 

It should be noted that you can’t just have any type of NEMA 14-50 outlet installed when it comes to EV charging. You will need one that can withstand the electrical demands of EV charging. Many on the market have fiberglass insulators that melt away after a few months of charging. You will need an industrial-grade NEMA 14-50 240v outlet that uses glass or ceramic insulators.

What type of work does an electrician do for a NEMA 14-50 outlet installation?

An electrician will work with you to figure out the best location for the EV charging outlet. Factors like how far your intended location is from the panel will determine how long the installation will take and how much it will cost. 

Then, the electrician will perform load calculations and determine if your electrical panel can handle the additional load of EV charging. If your panel does not have enough space, then the electrician will have to upgrade your subpanel at an additional cost. Once the circuit’s total load is determined the electrician can then determine what type of breaker box your installation will need. Breaker boxes come in different amperage ratings. 

From there, they will identify a circuit plan and determine what is the best path for the conduit (through the attic or behind drywall, for example). Then, they will install electrical boxes for every switch and outlet in the new circuit. This process may require cutting holes in the ceiling or walls. 

Next, the conduit will be run through the electrical boxes.  This is a time-consuming task that requires knowledge of safe ways of storing conduit and ways to prevent future electrical catastrophes, like someone drilling into the electrical wire.

Then, the conduit will be run to the breaker box. The electrician will wire the breaker box for the new breaker. This part of the process requires electrical knowledge that Do-it-Yourselfers should not take a risk with. Trying to save a few extra bucks can lead to a house fire, which is a huge safety and financial concern.

Next, they will wire the new circuit breaker. This part of the process also requires deep electrical knowledge and is not something you should risk doing yourself.

From there the electrician will replace the panel cover and test the NEMA 14-50 outlet with a test kit or your EV charger to ensure it is working properly. 

Can a normal electrician install an EV charger?

Yes, a licensed electrician should be able to install an EV charging station. The process is not particularly complicated, but there are some important safety considerations that need to be taken into account. Electric vehicles contain large batteries that store a significant amount of energy, and that energy needs to be properly managed in order to avoid any accidents. A licensed electrician will have the training and experience necessary to safely install an EV charging station.

Installation of EV charging equipment is not the same as typical electrical work. In most cases, the electric vehicle charger installer will be working with higher currents and will likely need to have a deeper understanding.

There are also specific National Electrical Code (NEC) requirements regarding the electrical installation of an EV charging point that an EV charger installer needs to be familiar with. For example, a NEMA 14-50 outlet must be installed on a GFCI breaker. Failure to follow the code requirements can result in a bad installation or even worse, an unsafe installation that can result in disaster. 

Even the most experienced electricians may not be familiar with the special requirements for home charging installations. That’s why it’s always best to work with an EV charging installer who knows everything about the process. They will be able to advise you on the best way to set up your home charging station, taking into account your individual circumstances.

And they’ll make sure that the installation is carried out safely and in accordance with all the relevant regulations. So if you’re thinking of getting an electric car, make sure you find a qualified EV charging installer to help you get set up. It’ll make life a lot easier in the long run.

Can you charge a Tesla with a NEMA 14-50 outlet?

If you are a Tesla owner, whether you own a Tesla Model S, Model 3, Model X, or Model Y, you can charge your car through a NEMA 14-50 outlet, but you will need an adaptor. The good news is every Tesla purchase comes with a 14-50 NEMA adaptor. To use the adaptor you will need your Mobile Connector, which is also included with the vehicle. The Tesla Motors Mobile Connector is a 20-foot-long cable with interchangeable adapters which can be used in different outlets. To start charging with your 14-50 outlet, attach the adaptor to the Mobile Connector and then plug it into the electrical outlet.

How much does a NEMA 14-50 outlet installation cost?

The cost of a NEMA 14-50 installation varies depending on how far your power source is from the outlet, if you need a subpanel upgrade, and how the conduit is run through your house. The overall cost also takes into account any permitting fees.

The cost of an installation for a NEMA outlet installation ranges from $500 to $2,500.
