Are you considering purchasing an electric vehicle (EV)? Or have you already made the leap to sustainable transportation? Congratulations! EV’s are so much fun! EVs are becoming increasingly popular due to their eco-friendly nature and cost-saving benefits. The cost-saving benefits after acquisition are very noticeable. A crucial aspect to consider when owning an EV is the installation of a home EV charger. To ensure a safe and efficient charging experience, it’s essential to determine the right size breaker for your EV charger. The breaker is indispensable. Compare it the breaks on your vehicle. They are installed for safety reason. MaCharge will guide you through the process and answer your burning question we get asked often: “What size breaker do I need for an EV charger?”
Understanding the Basics
Before delving into the technicalities, let’s start with the basics. The breaker is a protective device that automatically shuts off the electrical circuit in case of an overload or short circuit, preventing electrical fires and other hazards. To determine the appropriate breaker size for your EV charger, you need to consider factors such as the charging speed, the maximum current the charger can handle, and the capacity of your home’s electrical system.
Evaluating Charging Speeds
EV chargers come in different power ratings measured in amps (A). The most common levels of charging for home use are Level 1 (120V) and Level 2 (240V). Level 1 chargers are slow, providing approximately 5 kilometers of range per hour of charging, while Level 2 chargers are significantly faster, offering around 48 kilometers of range per hour. To ensure you have an optimal charging experience, a Level 2 EV charger is recommended. Most wall outlets that people are using are not meant to charge a car for 20 plus hours. A Level 2 charger significantly reduces charging time, allowing you to enjoy your EV to its fullest potential. Let’s determine the breaker size for a Level 2 EV charger.
Calculating Breaker Size
The breaker size for your EV charger depends on the charging speed you desire, as well as the maximum current the charger can handle. Most Level 2 chargers have power ratings ranging from 16 amps to 40 amps. Let’s explore how to determine the appropriate breaker size using these values. The most common breakers we install 40-Amp and 50-Amp breakers. We routinely install 48-Amp breakers but we find it “overkill” in many situations.
32 Amps: If your EV charger is rated at 32 amps, you should choose a 40-amp breaker. This allows for a sufficient safety margin and ensures your breaker won’t trip during charging.
40 Amps: For a 40-amp EV charger, you’ll need a 50-amp breaker. Again, this provides a safety buffer and avoids unnecessary breaker trips.
It’s important to note that the Electrical Code stipulates that a continuous load should not exceed 80% of the circuit’s maximum capacity. Considering this, a 50-amp circuit is the minimum requirement for a 40-amp EV charger.
Seeking Professional Electrical Advice
While the above guidelines serve as a general rule of thumb, it’s always a must to consult a qualified electrician or an EV installer before making any decisions. The purpose of this blog is that you can understand what your electrician is doing a little better. Your electrician will assess your home’s electrical situation and provide expert advice tailored to your specific requirements. A professional electrician can evaluate the capacity of your electrical panel and make recommendations based on local electrical codes and safety regulations.
