Signs You Need a
Panel Upgrade.

Most Connecticut homeowners don't know they need a panel upgrade until something goes wrong. Here are the most common signs that it's time to call a licensed electrician in Connecticut.

Breakers Tripping Constantly
If breakers trip frequently or won't reset, your panel is overloaded. A 200-amp upgrade solves this.
Fuse Box Still Installed
Fuse boxes are outdated and often fail insurance and real estate inspections in Connecticut.
Adding EV Charger or Generator
EV chargers, standby generators, and central air or mini-split HVAC systems all require a panel upgrade to 200 amps in most Connecticut homes. Most homeowners looking at mini-split systems don't realize a service upgrade is part of the project.
Home Addition or Renovation
Adding square footage or a new room often requires a panel upgrade to handle the additional electrical load.

Common Questions

Panel Upgrade
Questions Answered.

A 200 amp service upgrade Connecticut typically costs $1,500–$3,500 depending on whether the meter socket and service entry need to be replaced as well. If only the panel itself needs replacing, costs are on the lower end. We provide free written quotes — call (860) 496-0315 or request online. No hidden costs, no surprises.
Most 200 amp service upgrades in Connecticut are completed in one day. You'll be without power for approximately 4–6 hours while Eversource disconnects and reconnects the service. We schedule Eversource in advance so the whole process is coordinated — no surprise outages.
Yes — always. A Connecticut electrical permit is required for every panel upgrade. Any electrician who skips the permit is cutting a corner that could cost you at closing, void your homeowner's insurance, or create a safety hazard. Konopka Electric pulls every permit and schedules every inspection — it's non-negotiable.
Most Connecticut homes with 100-amp service need a panel upgrade before installing a Level 2 EV charger. A 200-amp service gives you enough capacity for the EV charger plus your home's existing load. We do a load calculation before every EV charger installation to confirm — and if an upgrade is needed, we can do both as a single project.
Sometimes — if your existing panel has open breaker slots and enough capacity for the new load, we can add circuits without a full panel upgrade. We do a load calculation to determine this. If your panel is at capacity or you have a fuse box, an upgrade is the right move. We'll always give you an honest assessment before recommending any work.
