The NEMA 14-50 is a 240-Volt 50-Amp socket. A 240-volt dedicated circuit installed for higher-power devices can be wired as a 14-50 line. High power devices such as electric stoves or welders, are typical applications for level 2 chargers. They are also often used for RV and mobile homes.
The NEMA 14-50 standard socket is US-based and most commonly used for charging electric vehicles. With an appropriate EV charger, it can be used to completely recharge a modern EV battery in fewer than 8 hours.
14-50 NEMA chargers are a type of pluggable device that plugs into an outlet. Some similar devices may be hard-wired to the power grid, thus restricting them from moving.
All of the chargers models under consideration are widely compatible with various non-Tesla electric cars thanks to the J1772 connector. It also charges Tesla cars perfectly when using the included adapter.
The NEMA 14-50 standard specifies a maximum current of 50A. However, according to the NEC 1 , only 80% of the maximum power is allowed for continuous use. This means that plugging in any charger (even one labeled 50A) will not produce more than 40A for an EV.
Why do customers choose plug-in devices over hardwiring?
1. The charger remains mobile. It can be unplugged at any minute, stowed in the trunk, and used elsewhere.
2. When traveling, you can find access to a 240V outlet, such as for an RV, where the charger plugs in easily.
3. There is an option to plug the charger into your own dryer outlet via an extension cord. This is relevant when you do not want to or cannot have new wiring put in.
4. If your unit becomes defective during the warranty period, you can easily unplug it and send it to the manufacturer for replacement. And you don’t need to call an electrician to remove it.
5. You can use cheaper NEMA extension cords, as opposed to J1772, when someone parks in the driveway needs to charge it.
6. Even if a new outlet has to be installed, the cost won’t exceed the hard installation.

How do I choose the right home charging station for my EV?
You should consider the following factors before purchasing a home charging station:
1) What is your daily driving range?
2) Do you have access to an electrical outlet at your parking spot?
3) How much power will you need to fully recharge your car overnight? (see below for a list of average power requirements)
4) Are there any local or state rebates or incentives available to offset the cost of a home charging station? If so, you’ll need to do some research into what is available in your area.
5) How much will it cost? You can find this information by checking with your local utility company.
6) Will you be able to install it yourself? Some people might not have the technical know-how, so for them, hiring an electrician is a must.
7) Does your current electrical panel provide enough amperage for your new charger? You can use this link to get an estimate on your amperage needs.
8) How long do you want it to take to recharge your car? If you’re looking for a rapid-charging station, keep in mind that they can recharge up to 80% of the battery pack in about 20 minutes. If you’re more interested in a standard charger, it can take up to 5 hours or more for a full charge.
9) How do you want to pay for the system: with cash, loan, lease, etc.? If you’re not able to purchase and install your own charging equipment at this time and need to rent2 one, keep in mind that most EVSE providers also charge installation fees. Be sure to do the math and compare what you’d pay in monthly rental charges vs. what it would cost to own your own NEMA 14-50 charging station over a certain period of time.
