Best 30 Amp Electric Car Charger (2024)

This guide lists the best 30-amp electric car chargers and how to install them in your home, a level 2 30-amp charger should be installed with a dedicated 30 amps circuit breaker, If you have a standard 30-amp electric vehicle branch circuit for EV charging, the 80% rule outlined in the National Electrical Code (NEC) for continuous loads like electric vehicle (EV) charging dictates that the 30-amp electric car charger shouldn’t exceed 80% of 30 amps (0.8 x 30 amps) = 24 amps.

A 30-amp electric car charger Level 2 EV charger can be a plug-in EV charger installed with a NEMA 14-30 or a NEMA 14-50 Outlet, it can also be a hardwired Level 2 EV charger depending on your installation choices and the charger specifications.

Depending on your home’s electrical supply, you can use a 240V 30-amp single-pole breaker or a 240V 30-amp double-pole breaker which is designed to handle a maximum of 30 amps, when the current of the Level 2 EV charger exceeds 30 amps the EV charger breaker trips, interrupting the flow of electricity in the electric vehicle branch circuit to protect your home electrical system from damage and electric vehicle charging fires.

According to the National Electrical Code (NEC) guidelines, a circuit cannot be loaded beyond 80% of its capacity. This is to prevent overheating and potential fire hazards. Therefore, on a 30 amp circuit, the usable amperage for continuous charging we used to test all the chargers in this review was 24 amps (30 amps * 80%).

This translates to a maximum charging rate of around 5.8 kW. While this might be slightly less than the 7.2 kW achievable if ignoring NEC rules, it ensures safe operation within the recommended parameters. Testing this 30-amp electric car charger added approximately 17-20 miles of range per hour, a significant improvement over a standard 110v outlet. The trade-off is a slightly slower charging speed for guaranteed safety compliance.

The diagram below shows a typical electric vehicle branch circuit of a 30-amp electric car charger connected with a 10-gauge wire to a dedicated 30-amp circuit breaker enclosed in a 240V electrical panel.

This diagram showcases a typical 30-amp Level 2 EV charger setup for your home, following the NEC's 80% rule for continuous loads. Power flows from the main breaker in your 240V electrical panel, following a dedicated circuit protected by a 30-amp breaker. A thick 10 AWG wire carries this 240-volt power through a protective conduit to the EV charger.  Inside the charger, a terminal block connects the hot, neutral, and ground wires. The key point is that the charger itself is set to a 24-amp output, adhering to the 80% rule to prevent overloading the 30-amp circuit.
