Electrical Panel Upgrade in Hanover, NH
If your Hanover home or business is still running on a 100-amp — or older — electrical panel, it may not be able to safely handle modern electrical demand. EV chargers, heat pumps, electric ranges, and home additions all require dedicated circuits that older panels simply weren't designed for. The good news: a panel upgrade is one of the most impactful electrical investments you can make.
Prosper Valley Electric handles electrical panel upgrades throughout Hanover and the Upper Valley. We're based in Woodstock, VT — just across the Connecticut River from Norwich, VT — and we manage the entire process from assessment to permit to inspection. No subcontractors, no surprises.

Breakers that trip frequently — If you're resetting breakers regularly, your panel may be overloaded.
Fuse box instead of circuit breakers — Fuse-based panels are a sign of very old infrastructure and an insurance liability in most states.

Home is 40+ years old with original electrical — Many Hanover homes of that era were built with 60 or 100-amp service that doesn't meet today's needs.

We handle all permit filings with the Town of Hanover building department. Downtime is typically 4–6 hours for a standard upgrade.
