Factors that affect panel upgrade cost
Amperage Rating
A 200-amp panel costs more than a 100-amp panel. Most modern Vermont homes need 200 amps to support EV chargers, heat pumps, and electric appliances.
Panel Brand
Square D, Siemens, and Eaton are the most common brands in Vermont. We use UL-listed panels with a lifetime warranty.
Meter Base Condition
If your meter base is corroded or undersized, it must be replaced. This adds $300-$800 to the project and may require coordination with Green Mountain Power.
Wiring Condition
Older homes may need wiring upgrades to meet current code. If your existing wiring is degraded or undersized, we will explain what needs to be replaced and why.
Panel Location
If your panel is in a tight or hard-to-access location, installation takes longer. Outdoor panels require weather-rated enclosures.
Circuit Count
More circuits means more breakers and more wiring. A panel with 40 spaces costs more than one with 20, but gives you room for future expansion.
Signs your panel needs an upgrade
If you are experiencing any of these issues, it may be time for a panel upgrade:
Frequent breaker trips — If your breakers trip when running multiple appliances, your panel is overloaded.
Burning smell or warm panel — This is a safety hazard. Turn off the main breaker and call us immediately.
Federal Pacific or Zinsco panel — These brands have documented failure rates and should be replaced regardless of age.
Adding an EV charger or heat pump — These require significant electrical capacity that older panels cannot provide.
Two-prong outlets — Your home may have outdated wiring that needs grounding and a panel upgrade.
Insurance requirement — Many Vermont insurance companies require panel upgrades for homes with older equipment.
Why upgrade to 200 amps?
- Supports EV chargers, heat pumps, and electric appliances
- Meets current Vermont electrical code
- Required by most insurance companies
- Increases home resale value
- Eliminates Federal Pacific and Zinsco safety risks
- Provides room for future expansion
