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 →

Cost of a Panel Upgrade in Knoxville
