What is a Level 12 AMP EV Charger?

A 12 Amp EV charger delivers up to 2.88 kW (Level 2, 240V) or 1.44 kW (Level 1, 120V), depending on the circuit and voltage. It typically provides 3–8 miles of range per hour, making it ideal for overnight charging, light daily use, or situations with limited electrical capacity. These chargers require a dedicated 15A circuit with 14 AWG wiring and must comply with NEC 80% load rules. Depending on the setup, they may be hardwired or plugged into outlets such as NEMA 5-15 (Level 1) or 6-15 (Level 2).

12 Amp Level 1 charger vs 12 Amp Level 2 charger

While both 12 Amp Level 1 and Level 2 chargers draw the same current, their voltage differences result in distinct charging speeds and setup needs.

12 Amp Level 1 Charger

Uses a standard 120V outlet (NEMA 5-15) on a dedicated 15A circuit with 14 AWG wiring. Delivers up to 1.44 kW, adding roughly 2–4 miles of range per hour. Ideal for overnight charging, low-capacity home load panels, and low-mileage drivers who don’t need fast turnaround. Easy to install using common household outlets; GFCI protection and proper grounding are essential for safety

12 Amp Level 2 Charger

Uses a 240V outlet (typically NEMA 6-15) on a dedicated 15A double-pole circuit with 14 AWG copper wiring. Delivers up to 2.88 kW, adding 3–8 miles of range per hour. Well-suited for overnight charging or light daily driving needs where electrical capacity is limited. It may be hardwired or plug-in, with GFCI protection required and compliance with NEC standards for circuit load, wire sizing, and installation safety. Professional installation is recommended if a 240V outlet is not already in place.

12 Amp Level 1 EV Charger Circuits

A 12 Amp Level 1 EV charger must be connected to a dedicated 120V circuit using a single-pole 15A breaker. The circuit should be wired with 14 AWG solid copper conductors (hot and neutral) and a 14 AWG copper ground, rated for at least 75°C insulation (THHN or equivalent). These chargers typically use a standard NEMA 5-15P outlet. GFCI protection is required in most residential installations and must be installed per local electrical codes.

NEMA 5-15P 12 Amp Level 1 EV Charger Circuits Wiring Diagram

The diagram below shows a 120V dedicated branch circuit wiring for a 12A Level 1 EV charger (1.44 kW) using a NEMA 5-15P outlet. A 15A single-pole breaker feeds three 14 AWG copper wires — black (Hot), white (Neutral), and green (Ground) — through a conduit to the outlet. A plug-in 12 Amp EV charger (NEMA 5-15 Charger)
connects to the receptacle.

An informative wiring diagram titled "NEMA 5-15P 12 Amp Level 1 EV Charger Circuits Wiring Diagram," created by Electric Vehicle Geek. The diagram illustrates the proper electrical connection for a 12-amp, 120V Level 1 EV charger using a standard NEMA 5-15P outlet. It shows a 120V electrical panel with power coming from the utility. Inside the panel, a "15A Dedicated Single Pole EV Charger Breaker" is installed. A hot wire (black) connects to the breaker, a neutral wire (white) connects to the neutral busbar, and a ground wire (green) connects to the ground busbar. These three wires, specified as 14 AWG copper, run through a conduit to a NEMA 5-15P outlet. An EV charger with a compatible plug is shown connecting to this outlet. Key information and warnings are highlighted throughout the diagram: "A 12A charger needs a 15A breaker per NEC 80% rule." "Active lugs are continuously live, regardless of whether the main breaker is ON or OFF." "Keep branch circuit wiring outside gutter posts and avoid crossing wires over breakers." "Upsize wires on long runs to keep voltage drop under 3% per NEC." The final charger is specified as a "12 Amp Level 1 EV Charger, 1.44kW.

If you’re installing a 12A Level 1 charger, make sure your setup includes a high-quality NEMA 5-15 outlet rated for continuous EV charging. Explore the best NEMA 5-15 outlets for EV use to ensure long-term safety, durability, and code compliance.

12 Amp Level 2 EV Charger Circuits

A 12 Amp Level 2 EV charger must be connected to a dedicated 240V circuit using a double-pole breaker rated for 15 amps. The circuit should be wired with 14 AWG solid copper conductors and a 14 AWG copper ground, rated for at least 75°C insulation (THHN or equivalent). These chargers may be hardwired or installed using a NEMA 6-15 outlet, depending on the charger’s configuration. GFCI protection is typically required and must be installed per local electrical codes.
