Most pre-1990 homes in Tolland County still run on 100-amp panels built for a simpler time. Today’s demand—home offices, AC, appliances, EVs—pushes them to the limit. Signs include tripping breakers, dimming lights, or no space for new circuits. Many homeowners don’t realize the panel is the issue until insurance or a home sale flags it.
What We Check — And Why It Matters
At Rosa Electric, we look beyond amperage: breaker condition, wiring, panel reliability, and overall capacity. Most upgrades go from 100 to 200 amps, giving you room for modern needs and future additions. We handle permits, coordinate with Eversource, complete the install, and schedule inspection.

Here is exactly what we handle when you book an electrical panel upgrade with Rosa Electric.
Before we quote anything, we assess your existing panel, check breaker condition, and calculate your current electrical load to confirm the right panel size for your home and planned usage.
We coordinate with Eversource to schedule the temporary service disconnect required during the panel swap, so the sequencing is handled and you're not waiting on the utility after we're ready to go.
We remove your existing panel, install the new 200-amp panel in the same location or a code-compliant location, and transfer all existing circuits to the new breakers correctly.
Every circuit gets verified for proper load and labeled clearly in the new panel, so you know exactly what controls what — not just guesswork written in pencil from a previous owner.
We pull the required electrical permit with your municipality before work begins and schedule the final inspection with the building department once the installation is complete.
All materials installed are covered by our one-year material warranty — if something fails on our end, we come back and handle it.
A panel that was installed without proper permitting, load calculation, or utility coordination creates problems that show up months or years later — and they're usually expensive to fix.
Permits Keep You Protected
Unpermitted panel work often gets flagged during home sales or insurance checks—doing it properly keeps everything documented and defensible.
Proper Load Calculation Is Critical
Skipping load calculations can leave your panel overloaded or oversized—accurate sizing ensures safe, efficient performance.
Quality Components Improve Reliability
Older panel brands can have failure issues—using reliable breakers improves safety and long-term performance.
Utility Coordination Keeps Projects On Track
Poor coordination with Eversource can delay projects—handling it properly keeps installation smooth and on schedule.

An electrical panel upgrade is one of the primary electrical services Rosa Electric offers — you can see the full list on the Rosa Electric homepage at rosaelectricct.com
If your home still has a fuse panel rather than circuit breakers, this is the version of the upgrade that applies to you — same result, different starting point.
After a panel upgrade, many homeowners add dedicated circuits for appliances, EV chargers, or home offices that couldn't be supported before.
Standby generator installations require a transfer switch connected to your panel — an upgrade is often the right time to plan for that connection if a generator is on your list.
A panel upgrade is one of the best times to add whole-home surge protection, since the surge protector ties directly into the new panel before the job is closed out.

Final Walkthrough

If your panel is a 100-amp service and you're running a modern household — central AC, multiple large appliances, a home office, maybe an EV charger — you've likely outgrown it regardless of whether anything is visibly wrong. If breakers are tripping regularly, the panel feels warm, or you're out of open slots for new circuits, those are signs the panel itself needs to be replaced rather than patched. When we come out, we'll tell you honestly which situation you're in. If a repair is the right answer, we'll say so — we're not going to sell you a full upgrade if you don't need one.
Yes. A panel replacement requires a temporary service disconnect, which means your power will be off for a portion of the day while the work is done. We coordinate that disconnect with Eversource ahead of time so it's scheduled and not a surprise. Most panel upgrades in a single-family home are completed in one day, so you're typically without power for a matter of hours rather than overnight.
Yes, an electrical permit and inspection are required for panel upgrades in Connecticut — no exceptions. We pull the permit before we start, do the work, and then schedule the final inspection with your town's building department. The inspector verifies the installation meets current code before the job is officially signed off. Our license number is E1-0184929 and we've been pulling permits in Tolland County towns for over 40 years, so this part of the process is routine for us.
That's a smart question, and yes, it's worth looking at the broader picture while we're already on-site. Older homes in this area sometimes have wiring that's deteriorated, outdated grounding, or circuits that were added over the years without permits. We can do a general assessment while we're there and flag anything that needs attention. It doesn't add cost to the estimate just to take a look — and if something does need to be addressed, we'll price it separately and get your approval before touching anything additional.
If you're in Tolland County or the surrounding area and need electrical work, give us a call. We've been doing this for over 40 years, and we're not going anywhere.
