Electrical Panel Upgrades for EV Chargers in Knoxville

Last verified: May 2026

Many Knoxville homes, particularly in historic neighborhoods like Fourth & Gill, Sequoyah Hills, and parts of North Knoxville, have 100-amp electrical service that cannot safely support a Level 2 EV charger. A panel upgrade resolves this, and the combined project (upgrade + charger install) can often be completed in one or two visits.

Do You Need an Upgrade?

Check your main breaker, if it says 100A, you almost certainly need an upgrade. If it says 200A, you likely don't (though a full panel may still require a subpanel). Full panel assessment guide →
