NEMA 14-50's are outdated technology: here's why

Things you need to know about charging with an outlet

Car Charger Rebate Program through Austin Energy

All 240-volt receptacles (6-50, 14-50, 10-30, 14-30, 6-20) have to be GFCI protected now per the 2020 code.  
This creates redundant GFCI protection as the car has GFCI protection built-in as well.
When the car runs it's self-test cycle of the GFCI in the car, it has a tendency to trip the GFCI breaker and you can't resume charging until you reset the breaker.
Due to this, we have been recommending a hardwired charging station instead of a receptacle.
Since there is no receptacle to plug something else in, a hardwired charging station doesn't need a GFCI breaker to be installed if it has integrated GFCI protection, which most do.

We install many charging stations every week including Tesla's wall connector, the ClipperCreek charging stations, and a variety of 240 volt receptacles.  All systems require their own dedicated circuit and run on 240 volts.  Amperages can vary.  The Tesla wall connector has options that allow it to run on up to a 60 amp circuit.  To install a charging station, we’ll need to know what type of power you need and the distance from the breaker box to the location you want the charging station.  Some models require a receptacle to plug the station into, while others are hardwired into the home's electrical system.

We recommend installing a hardwired charing station. Tesla Wall Connectors are made specifically for Tesla vehicles. They are a level 2 charging station which means that they're connected to 240-volt power and can be connected to a circuit up to 60 amps. The Telsa Wall Connector is a good option for Model 3 long-range, Model S, Model X, and Model Y drivers that drive many miles often. 

When Tesla's were first released there weren't many public charging station options, especially when on a long road trip so they sent a mobile connector cord with a NEMA 14-50 adapter so that in a pinch a driver could stop at an RV park and charge. When public charging stations started popping up along most major highways and interstates (and the standard range Model 3 which isn't capable of charging at 50 amps was released) Tesla stopped providing NEMA 14-50 adapters with all cars. 


With the GFCI requirement on all garage and outdoor receptacles causing nuisance tripping on all known electric cars (see video below). Tesla is no longer providing a mobile connector cord with all cars and it's only a matter of time before all electric car manufacturers follow suit. Now, the cost of a receptacle and the cost of a wall connector installation are about the same cost. Charging stations have been and continue to be a much better product than the NEMA 14-50 since National Electrical Code 2020 was adopted in the Austin area.
