Electrical Panel Upgrades in Greenwich, CT

Expand your capacity to support EV chargers, central heat pumps, and home additions.

Many Greenwich homes feature older 100-amp panels that cannot safely support Level 2 EV charging, central HVAC, or heavy kitchen renovations. We coordinate complete panel modernizations from older fuse boxes to safe, premium 200-amp or 400-amp breaker boards.

What to Expect in Digital Intake

We will collect details on your current electrical amperage, future appliance plans, and request panel photographs to compile a custom service upgrade quote.

Safe Photos & Documents Recommended

Photos of the main electrical panel (with the door open) and the outdoor utility meter location are highly useful.

Do not remove panel covers, open switches, or touch live wires to obtain images.

⚠️ Safety Disclaimer

Never open the inner safety cover plate of your panel. Only take photos with the outer swing door open.

Panel upgrades require stand-alone trade permits and inspections from the Town of Greenwich Building Department.

Frequently Asked Questions

How long does a panel upgrade take?

The physical swap usually takes 4 to 8 hours, during which power is temporarily shut off. We coordinate with Eversource and local inspectors to restore power swiftly.

What is the price difference between 200A and 400A panels?

A 200A panel is standard for most average-sized homes. 400A panel services are recommended for large estates, multi-car charging, and extensive pool houses.
