I would not get a plug-in charger UNLESS you planned on moving soon and want to take the charger with you without paying an electrician to disconnect it. They have a better connection to the car and a high range of charge rates to choose from. I am a huge fan of the hard-wired chargers for most scenarios. 1 Extra connection point (the charger plugs in!) that could break down over time.Slower charging speed when comparing the 50amp NEMA 14-50 to a 60amp hard wired connection.The most expensive! You need everything required for the NEMA outlet installation plus the cost of the wall charger itself.If you move, you can unplug your charger and take with you!.This means you are purchasing a wall charger (such as the ChargePoint home flex plug in) that requires a NEMA outlet to connect to. The final kind of installation is a combination of the two above installations. If you move and want to take the charger with you, you will need an electrician to disconnect it.If you select a Tesla wall connector, it will only charge Tesla cars (their may be an adapter available for this purpose).More expensive overall installation including charger cost.Cheaper electrical install (if you provide the charger).Large range of amperage / charge speed options.Hard wired chargers such as the Tesla wall connector and ChargePoint home flex can be used in various amperages and charge rates, from 15amp to 60amp and sometimes above. If we use a total cost of $250, this is still far less than a Tesla wall charger at $500 + tax/shipping and a ChargePoint home flex at $700 + tax / shipping. Then add the cost of the adapter ($40-$75) for the NEMA outlet you will need to buy for the car to connect. These differences can lead to a material cost increase of $200 or more depending on the length of the wire run. The labor for the installation of the two options is the same, the only difference is material cost. Take a look at the following cost chart to help clarify this even further as it comes up at most estimate appointments.Īs you can see above, the NEMA outlet installation requires these additional materials, a 4wire cable (instead of 3wire), NEMA outlet, box, cover, GFCI breaker (instead of standard) and adapter. However, when adding in the cost of the wall charger, plus electrical installation, the NEMA outlet will be cheaper. This is because of the additional electrical material needed to install the NEMA outlet. If you are providing the wall charger, the installation of it will be cheaper than a NEMA outlet. Tesla recommends leaving the adapter plugged in all the time for this reason.Ĭlarification: Yes it may seem like I contradicted myself here. If you are constantly plugging in and unplugging your adapter, the outlet will wear out. The adapter you have for your car will plug into the NEMA outlet. These outlets rely on a pressure connection.You will likely need to buy an adapter to charge your car.Requires a GFCI breaker, box, NEMA outlet, and cover to install leading to a higher material installation cost.Slower charging speed when comparing a NEMA 14-50 to a wall charger at 60amps (this is a common comparison).Most wall chargers will have increments in 5-10amps, going up to 60amps and sometimes above. Less amperage / charging rate options.Overall cheaper to install than purchasing an expensive wall charger.All cars will charge using a NEMA outlet, it does not matter what brand car. Decent range of charging sizes, from 15amps to 50amps.14-50 outlets are much more common then 6-50’s, but either one will work! NEMA 14-50 vs NEMA 6-50r – The 14-50 is a 4wire outlet (2 hots, 1 neutral, 1 ground), the 6-50r is a 3wire outlet (2 hots, 1 ground). NEMA 240volt outlets come in the following amperage ratingsįor most cars they will require a separate adapter to be purchased to work with the corresponding NEMA outlet. For example, a Tesla will charge at roughly 3 miles per hour using one of these standard outlets. Yes, these can charge your car but at a painfully slow speed. There are NEMA outlets which use 120volt and are the most common outlets found around your house. When discussing NEMA outlets we will be referring to the 240volt variations. This is a question asked daily by our customers, which one should they choose? There are some pros and cons to both options.
