When a panel upgrade is required
Panel upgrades are common when the existing service cannot support the generator load, or when older panels lack modern safety features. Installers check amperage, breaker space, and compatibility with transfer switches.
Typical cost range
Panel upgrades are one of the biggest price variables because they add parts, labor, and permit complexity. Costs rise if service relocation or meter upgrades are required.
Ways to reduce scope
- Use load management or essential circuit coverage instead of whole-home backup.
- Consolidate circuits to free up breaker space when permitted.
- Coordinate electrical and generator work to avoid repeat inspections.
