Panel Upgrade Offering Tiers

Contractors typically package panel work into three tiers. A panel replacement swaps a defective or recalled panel at the same amperage — the scope covers removal, new load center installation, circuit transfer, testing, and inspection. A service upgrade increases amperage (e.g., 100 A to 200 A) and adds a load calculation, permit, new service entrance conductors, utility coordination, and inspection. A heavy-up with additions combines the upgrade with new dedicated branch circuits for loads such as EV charging, HVAC, or solar, and may include a sub-panel.
