A 50 amp car charger outlet provides a significant advantage in a 50A EV charging circuit by delivering higher power to 40A plug-in Level 2 EV chargers.
A 50 amp car charger outlet prevents Level 2 EV chargers from power throttling, voltage drops, overheating circuit components, tripping off the EV charger circuit breaker, reduced efficiency, or potential damage to both the EV charger and the vehicle’s onboard charging system due to a mismatched power supply.

What is a 50 Amp Car Charger Outlet?
A 50 Amp Car Charger Outlet is a high-capacity electrical outlet designed specifically for powering 40A plug-in Level 2 EV chargers. It is installed in a dedicated EV charger circuit protected by a dedicated 50A EV charger circuit breaker and connected with 6 AWG wires. Depending on the outlet type, it may use either a four-prong or three-prong configuration.
50A EV Charger Outlet Configurations
50A EV charger outlets are available in two configurations depending on the plug-in EV charger plug type, the configuration determines how the 50A car charger outlet is wired, and how the electrical current is delivered to the EV charger.
Match Your 50 Amp EV Charger Outlet with Your Plug Type
There are two main 50A EV charger outlet configurations, a four-prong configuration (NEMA 14-50), and a three-prong configuration (NEMA 6-50), Understanding these configurations ensures that your EV charger outlet is compatible with your EV charging circuit wiring, and EV charger plug type.
Four-Prong 50 Amp EV Charger Configuration (NEMA 14-50)
The most widely used configuration for 50A car charger outlets is the NEMA 14-50 four-prong setup. This outlet type is designed for 240-volt circuits and features:
- Two hot wires (6AWG): These carry 240V of electricity.
- One neutral wire (6AWG): This allows for a balanced load in the circuit, ensuring the safe distribution of power.
- One ground wire (6AWG – 8AWG): This provides an additional layer of safety by protecting the system from electrical faults.
We recommend the NEMA 14-50 as the best 50 Amp EV charging receptacle/outlet for most modern Level 2 EV chargers, as it meets safety standards and provides efficient charging for Level 2 EVs. It’s also compatible with a wide range of Level 2 EV charging stations, making it the go-to choice for homeowners looking to install a high-powered plug-in Level 2 EV charger.

Bryant 14-50 Outlet for Level 2 EV Charger Installation (Plug-In)
Leviton NEMA 14-50 Outlet for Level 2 EV Charger Installation (Plug-In)
We recommend the above NEMA 14-50 outlets for 50 Amp EV charger circuits due to their ability to support balanced power delivery with a neutral wire. This configuration enhances charging efficiency while reducing risks such as overheating, slow charging, circuit breaker trips, and voltage drops in a 40A Level 2 EV charging setup.
Three-Prong 50 Amp EV Charger Configuration (NEMA 6-50)
Three-prong configurations are common in older homes or systems with outlet circuits that don’t feature a neutral wire. The most widely used three-prong 50 Amp EV charger outlet is the NEMA 6-50, which is designed for 240-volt circuits and features:
- Two hot wires (6 AWG): Again, these provide 240V of electrical power.
- One ground wire (6 AWG to 8 AWG): Used to protect the system in case of faults.
Unlike the four-prong setup, the three-prong configuration lacks a neutral wire, which limits its usage with some modern EV chargers. While still functional in certain circumstances, this configuration is not as widely recommended for new installations due to its limitations in ensuring safe and balanced power distribution.
