If you are purchasing a charging outlet for your new Tesla car, you might choose not to opt for level 1 charging like your usual wall outlet. You might be advised to settle for the faster level 2 outlets to help charge your electric vehicle in your garage. If you decide to go for a level 2 charger outlet for your electric vehicle, you will be torn between the NEMA 14 50 and the 6 50.

These are two of the common variants of EV chargers that manufacturers have chosen to model their chargers after. In terms of the plug, you either get a NEMA 14 50 or the newer 6 50 outlet. While they are both level 2 chargers, there are some pros and cons between them. This has led to people debating on the NEMA 14 50 and the 6 50. This review looks to examine all of that.

14-50 vs 6-50

The NEMA 6 50 charging station

The NEMA 6 50 charging plug is known to come with two straight hot prongs which run parallel to each other as well vs the horseshoe-shaped ground prong. However, the hot prongs which comes with the 6 50 come in various widths while the large prong is in the right. The NEMA 6 50 plug is used to connect to your 250 volt 50 amp electrical circuit to charge your car. The neutral wire is used for grounding.

However, this 50 amps electrical circuit usually works with either the 8 gauge or the bigger wires. The 50 comes with a round face which comes with a measurement of 2-1/8 inches across. This is used to mount to the standard wall outlet of the electrical box. Certain appliances such as electric welders that come with the 3 horsepower rating are able to connect to the power source by using the 6 50. This is good for arc welders.

The NEMA 14 50 EVSE charging station

The 14 50 mobile charger plug comes with a four wire grounding system which can be gotten in ratings from 15A to 60A. This option comes with a voltage rating of about 250 V. This wire outlet comes with a rating of 50 A as well as a straight neutral wire. This neutral wire is used for grounding. When installing this EVSE unit in your garage, you will need to consult an electrician to install the wires the proper way. You will need a 240V outlet with a 50 amp circuit amp breaker. This setting will be able to charge your Tesla Model 3 at about 30 miles per hour. If you install this units on your wall, you get a 50% faster charging rate.

Head to head: The 14 50 vs the 6 50

While the NEMA 14 50 starter plug has been in existence more than the 6 50, Tesla has stopped the shipping of their new vehicles with the 14 50 adapters. This means that opposed to the 6 50, the 14 50 is no longer the ideal charger receptacle for your electric vehicles to install in the house.

The NEMA 6 50 starter plug is now preferred over the 14 50 because of certain benefits that the 6 50 receptacle has over the 14 50. For instance, in the installation of the 6 50, you will not be needing an extra wire which is an additional cost for anyone. However, when installing the 14 50, you will need one more extra wire for this connector.

Then for the 6 50 there is a difference in the cable as you get a smaller cable diameter and which is more flexible in structure unlike the 14 50. Furthermore, compared to the 14 50, the 650 is very easy to install. In terms of the cost of the receptacles, it appears that the 650 receptacle is less expensive when compared to the price of the 14 50 receptacle. This is one thing that Tesla owners need to consider if they wish to get a decent installation experience.

Still on the installation of the 6 50, you will need a lesser amount of wires for your wall breaker box which makes it quite easy to install. Unlike the 14 50 that needs a bunch of wires to complete its installation. With the analysis of the difference of the 6 50 from the 50, it looks like the 6 50 is a more improved version of the 50.

The NEMA 14 50 is still widely used in a lot of chargers because it is still currently the ideal level 2 charger plug for the Tesla charging station. This means that the 14 50 is likely to stay on for a while. Then the NEMA 14 50 comes with certain disadvantages over the 6 50. One of this is long term use, as it looks like EVSEs of the future will not be having the 6 50 receptacle alternative. However, we have j1772 EVSE chargers which currently use the 6 50 right now.

While the 14 50 receptacle can be used on an RV, the 6 50 receptacle is not something that you get to use on your RV. Then again, one good advantage of the 14 50 adapter connector from Tesla rather than buying the 6 50 means that you get to use this 14 50 adapter connector elsewhere apart from home charging. You could use the adapter when on the road. Moreover, it appears that the 14 50 adapter is more common than the 6 50 option.

In terms of flexibility, the 14 50 circuit for homes look more flexible than the 6 50. The 14 50 plugs are a standard adapter that is shipped along with your Tesla Model 3. Then again, one reason we prefer the 14 50 over the 6 50, is the fact that it comes with the neutral wire function, which allows you to use one and the same plug for different other functions. Furthermore, you will love the fact that you get to split up the 14 50 plug into two high current 120V outlets with the use of a simple adapter. However, this is not possible for the 6 50 as it only works with the 240V. The 14 50 plug comes with a higher installation cost, this is the choice users will have to face when they choose the 14 50 choice.
