Electrical Service Upgrades for Connecticut Homes That Have Outgrown Their Panel

Tripping Breakers Are a Warning, Not a Quirk

A breaker that trips once is doing its job. Breakers that trip repeatedly are telling you the panel can not distribute the load your home is placing on it. In many northeastern Connecticut homes built before 1980, the original 60 or 100 amp service was sized for a fraction of what a modern household runs — no EV chargers, no mini splits, no heat pumps, no home offices.

Common signs your home needs an electrical service upgrade:

• Breakers trip frequently, especially under normal household load
• Lights dim when large appliances start up
• You're planning to add an EV charger, mini split, heat pump, or hot tub
• Your panel has no open slots for new circuits
• Your home is still on 60 amp service

If any of these apply, the panel is the starting point — not a workaround.

Federal Pacific and Zinsco Panels: Know What You Have

If your home was built between the 1950s and 1970s, there's a real chance it still has a Federal Pacific Stab-Lok or Zinsco panel. Both brands have documented failure rates — breakers that don't trip when they should, creating a fire risk that standard operation won't reveal. These panels are among the most common hazardous electrical panels found in Windham County homes today.

Replacing a Federal Pacific or Zinsco panel is not a complicated job, but it is an important one. We remove the old equipment, install a modern code-compliant distribution panel, and coordinate the required utility inspection so the work is properly closed out. If you know you have one of these panels — or if you're not sure what brand you have — that's worth a call.

Adding New Equipment? The Panel Comes First

One of the most common reasons homeowners discover they need a service upgrade is during a new installation. Mini splits, EV chargers, electric vehicle charging stations, and heat pumps all draw significant load — and older panels often can't accommodate a new dedicated circuit without upgrades first.

When your mini split installer or EV charger contractor tells you the panel needs attention before they can proceed, that's not a delay. That's the correct sequence. We handle both sides of that project: the 200 amp panel upgrade and the connection for the new equipment. One contractor, one project, no handoff gaps.

Our electrical work covers the full scope of residential service upgrades in Connecticut, including:

• 200 amp service upgrades from 60 or 100 amp service
• Panel replacement and circuit breaker panel upgrades
• New circuit installation for high-draw appliances and EV chargers
• Coordination with the equipment installer when work is being staged

How an Electrical Service Upgrade Works in Connecticut

Homeowners doing this for the first time are often surprised that a panel upgrade involves more than just swapping the box. In Connecticut, a service upgrade requires coordination with Eversource — the utility provider for most of Windham County — as well as a permit and inspection through the local building department.

Here's how the process works:

Step 1: Assessment and Permit

We evaluate your current service, confirm the scope of the upgrade, and pull the required electrical permit with your municipality.

Step 2: Utility Coordination

We contact Eversource to schedule the service disconnect and reconnect. This step is required before the new meter base and service entrance can be installed.

Step 3: Panel Replacement and Rewire

We install the new distribution panel, transfer existing circuits, and add any new circuits required for the project scope.

Step 4: Inspection and Reconnect

The work is inspected by the local electrical inspector. Once it passes, Eversource reconnects service and the job is complete.

We manage every step of this process. You don't need to call Eversource separately or track down the permit yourself.
