How much does main electrical panel installation typically cost?

Main electrical panel installation cost is determined after an on-site assessment by Atomic Electric Service Inc., because price depends on the specific upgrade and existing conditions. The biggest cost swings usually come from increasing service size and correcting issues found at the current panel or service equipment. We back workmanship with a one-year craftsmanship warranty, and we honor manufacturers’ warranties on parts. Our team regularly completes panel replacements across the Maynardville area.

Key factors that change price:

• Panel amperage and the number of circuits to be accommodated
• Condition, accessibility, and location of the existing panel and feeders
• Needed service-entrance, meter base, grounding, or bonding upgrades
• Add-ons like whole-home surge protection, EV charging, or a generator transfer switch
