If you’re considering making the switch to an electric vehicle (EV), it’s essential to understand the electrical upgrades required to support efficient and safe EV charging at home.

Do You Have the Right Electrical Setup for EV Charging?

Electric vehicles typically require a 240-volt circuit for fast and efficient home charging. While this level of power isn’t standard in many homes, Zellner Electric can determine what upgrades are necessary by performing a comprehensive load calculation of your existing electrical system. We’ll evaluate whether your panel, service, and meter can handle the additional demand of a Level 2 EV charger installation.

Our licensed electricians will review your current setup and let you know if your panel needs a new breaker or if your electrical service requires a complete upgrade. With expert EV charger installers near you, we ensure the entire process—from consultation to installation—is smooth, code-compliant, and ready to keep your EV fully charged at home.
