This guide covers the installation of 24-amp electric car chargers in your home and lists the best 24-amp electric car charger options available. These chargers are often referred to as 30-amp EV chargers because they require a 30-amp circuit breaker.
The National Electrical Code (NEC) recommends limiting continuous loads like EV charging to 80% of the breaker’s capacity. So, a 30-amp breaker safely supports a 24-amp charger (0.8 x 30 amps) = 24 amps.

Charging Speed of 24-Amp Electric Car Chargers
A 24-amp electric car charger typically delivers around 5.8 kilowatts (kW) of power (24 amps x 240 volts). The actual charging speed depends on the vehicle’s battery capacity and efficiency. On average, a 24-amp charger can add about 20-25 miles of range per hour of charging, making it suitable for overnight home EV charging or quick top-ups throughout the day.
Installation of 24-amp Electric Car Chargers
You can install a 24 amp electric car charger in your main electrical panel or opt for a dedicated EV charging subpanel depending on your electric vehicle branch circuit complexity, you will need a 30 amp dedicated circuit breaker, and 10 AWG wires to connect the 30 amp circuit breaker with the 24-amp electric car charger as shown in the 24-amp electric vehicle branch circuit diagram below:

- The Grizzl-E Classic comes equipped with built-in safety features like ground fault circuit interruption (GFCI) and over-temperature protection, ensuring a safe charging experience.
For EV owners who prefer smart EV charging features such as mobile app control, real-time EV charging data, smart scheduling, Time-of-Use (TOU) compatibility, smart grid integration, and voice control they can opt for the Grizzl-E Smart Level 2 charger which also supports 24-amp EV charging electrical vehicle branch circuits.
The Grizzl-E Smart Level 2 charger supports all features of the Grizzl-E classic Level 2 EV charger and also adds on smart EV charging features, Smart EV charging offers tech-savvy drivers, cost-conscious owners, and eco-friendly users remote control, money-saving options, and a greener charging experience.
Grizzl-E Level 2 EV Charger (24-Amp) Installation
Installing both the Grizzl-E Classic and the Smart Level 2 charger requires the use of a NEMA 6-50 or a NEMA 14-50 outlet depending on your electric vehicle branch circuit configurations and the specifics of the charger itself. You will also need a 30-amp dedicated circuit breaker and 10 AWG wires to connect the 30-amp circuit breaker and the NEMA outlet (NEMA 6-50 or NEMA 14-50 outlet).
Now that you understand the requirements, let’s focus on the two installation processes.
NEMA 6-50 24-Amp Grizzl-E Charger Installation
This setup utilizes a NEMA 6-50 outlet, a three-pronged connector (Two hot conductors and one ground) commonly rated for 50 amps. However, in this case, the circuit and charger are limited to delivering a maximum of 24 amps for safe and efficient charging of your electric vehicle which won’t have an effect on using the NEMA 6-50 outlet.
NEMA 14-50 24-Amp Grizzl-E Charger Installation
This option utilizes a NEMA 14-50 outlet, a four-pronged connector (Two hot conductors, one neutral, and one ground) typically rated for 40 amps, however, it’s perfect for 24-amp EV charger installations, similar to the NEMA 6-50 setup, the circuit and charger are limited to providing a maximum of 24 amps of charging current.
Grizzl-E Home Electrical Main Panel Installation
Depending on your electrical panel capacity, the complexity of your electric vehicle branch circuit, and the location of your charging spot, there are two ways you can install a 24-amp Grizzl-E charger, you can install the charger from your main electrical panel, or use a sub panel to extend the location or capacity of the main electrical panel.

Best Tesla 24 Amp Charger
We have listed the best Tesla 24 amp chargers below for Tesla owners looking for a reliable 24-amp charger to charge their Tesla, While the 24-amp chargers highlighted above are fantastic options for most electric vehicles (EVs) in North America, they won’t work directly with your Tesla. This is because these chargers utilize the J1772 connector, which is the standard for most EVs but not for Teslas. Tesla uses a proprietary connector type specifically designed for their vehicles.
Below, we’ve identified and tested the top-rated Tesla 24 amp chargers:
Tesla Wall Connector
The Tesla Wall Connector (24 amp version) is a tailored home charging solution designed specifically for Tesla vehicles, offering reliability and convenience. It mounts directly on the wall for a tidy installation, ensuring a seamless, plug-and-play experience when connecting to your Tesla. Safety is a priority with built-in protections for both your vehicle and home electrical system. Optional app control via the Tesla app allows for remote monitoring, scheduling of charging sessions, and receiving notifications.
Tesla Wall Connector 24 Amp Charger Installation
Unlike most J1772 chargers that offer plug-and-play options, the Tesla Wall Connector (24 Amp) requires professional hardwiring directly to your home’s electrical panel. This approach ensures a safe and reliable connection specifically designed for Tesla’s charging needs. However, depending on your existing electrical panel’s capacity, you might need to consider an additional installation option:
- Installation in your Home Electrical Panel: This is the most common scenario if your panel has enough spare capacity (amperage) to accommodate the Wall Connector’s 24-amp draw. A qualified electrician can assess your panel and perform the installation.
- Dedicated Subpanel Installation: If your main electrical panel is already maxed out, you might need a dedicated subpanel installed specifically for the Wall Connector. This subpanel would be fed from your main panel and provide the necessary dedicated circuit for the charger.
Why These Two Choices Exist:
- Safety and Performance: Hardwiring ensures a more secure and reliable connection compared to a plug-in option. This is crucial for the high currents involved in EV charging.
- Matching Power Needs: The installation method depends on your existing electrical capacity. A dedicated subpanel ensures the Wall Connector has its own dedicated circuit, preventing it from overloading your main panel.
