Tesla Wall Connector or NEMA 14-50 Outlet: What's the difference?

For new electric vehicles, the on-board charger capacity is matched to the vehicle battery. This means that charger can only accept power at its' maximum capacity. For instance, the Tesla Model 3 with a standard battery can only accept a maximum of 32 amps, you wouldn't hurt anything by plugging it into a Tesla Wall Connector that's wired for 50 amps but the car won't charge any faster since the battery doesn't have the ability to accept more than 32 amps at a time.

Car Charger Rebate Program through Austin Energy

We install many charging stations every week from Tesla's own station to Clipper Creek, ChargePoint, Juicebox and GE charging systems.  All systems require their own dedicated circuit and usually run on 240 volts.  Amperages can vary.  The Tesla station has dipswitches that allow you to adjust the amperage based on the car and the available power anywhere from 15 amps to 100 amps.  To install a car charger we’ll need to know what type of power you need and the distance from the main panel 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. 

Tesla cars come with a second generation mobile connector, it's a cord that comes with the ability to plug right into an outlet and charge the car with available power. The mobile connector is 20' long and comes with an adapter for a standard 15 amp 120-volt outlet and an adapter for a NEMA 14-50 which is a 50 amp 240-volt outlet. Although we will hook the outlet up at 50 amps (40 continuous amps) the mobile connector cord can only send 40 amps (32 continuous amps) to the car. For a Model S it's only the difference of 6 more miles per hour of charge, 8 hours of charging at 40 amps (32 continuous amps) would charge the car to go 184 miles. 


If charging faster is desired then a Tesla Wall Connector is the way to go, it can be hooked up at any amperage up to 100 amps. Most wall connectors are hooked up at 60 amps, which most homes can accommodate without requiring a main breaker panel and meter upgrade. The same Model S would charge at 34 miles per hour of charging at 60 amps (48 continuous amps) versus the 23 miles per hour of charging it would charge at with a NEMA 14-50 outlet with the mobile connector. While the wall connector does come with a much faster option to charge, the material for the wall connector alone before taxes runs $500. 


It may be easiest to determine how far you drive each day, generally, and how long the car is parked each day to best tell which charging option is best for you.
