Panel Upgrades for Kennebunk Homeowners

When Kennebunk homeowners need panel upgrades, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Kennebunk in York County — so we respond quickly and know the homes, the weather, and the codes in your area.
An outdated or undersized electrical panel can be a safety hazard and limit what your home can handle. Aces Highlands upgrades residential panels to meet modern demands -- from EV charger circuits to heat pump installations -- across Portland, South Portland, Scarborough, Westbrook, Gorham, and Greater Portland.
Many older homes in the Portland area still have 100-amp panels or outdated fuse boxes that cannot support modern electrical loads. We upgrade panels to 200-amp service, replace Federal Pacific and Zinsco panels, and install new breaker panels that meet current electrical codes. A 200-amp service is the standard for today's homes -- it gives you the headroom to run an EV charger, a heat pump, central air, and an electric range all at once without nuisance trips or overheating.
There are clear signs you have outgrown your panel: breakers that trip often, lights that flicker when an appliance kicks on, a fuse box instead of breakers, or no open slots left to add a circuit. Federal Pacific (FPE Stab-Lok) and Zinsco panels are a special concern -- their breakers are known to fail to trip during a fault, which is a real fire risk, and many home insurers in Maine now require them to be replaced. If your panel is warm to the touch, rusted, or has scorch marks, treat it as urgent.
A panel upgrade is often required before adding major appliances, EV chargers, heat pump installations, or finishing a basement. We handle the full scope -- pulling the permit, coordinating the service disconnect and reconnect with Central Maine Power, installing the new panel and meter base, transferring every circuit, and scheduling the municipal inspection. A typical 100-to-200-amp upgrade is a one-day job, and we keep your downtime to a few hours.
Every panel upgrade is performed by a Maine-licensed electrician and includes proper grounding, bonding, surge consideration, and clear circuit labeling. We test all circuits before we leave and walk you through your new panel so you know where everything is. While the panel is open, it is also the right time to address any outdated wiring in your home. Financing is available, and every estimate is free -- contact us to schedule.

Kennebunk Homes and What They Need
Kennebunk has the newest median home of the five York County coastal towns Aces studied, built in 1983, with under 19 percent of units predating 1940 and about 30 percent predating 1960. That newer stock still runs plenty of aging original heating and electrical systems worth a checkup.
Power, Storms and Wiring in Kennebunk
Electric service in Kennebunk is genuinely split: the Kennebunk Light & Power District, a municipal utility running since 1893, serves parts of town along with pieces of Wells, Arundel and Lyman, while Central Maine Power covers the rest. Before scheduling a panel upgrade or service change, we confirm which of the two utilities actually serves your address.

Getting to Know Kennebunk
Kennebunk broke off from Wells and Arundel to incorporate as its own town on June 24, 1820; the name comes from an Abenaki word describing 'the long cut bank.' Its Summer Street Historic District, home to the Federal-style Wedding Cake House, was the very first historic district in Maine listed on the National Register of Historic Places.
Kennebunk is also the hometown of U.S. Senator and Secretary of State Edmund Muskie and headquarters to Tom's of Maine. Since December 1893, part of town has been served by the Kennebunk Light & Power District, one of only two municipally owned Light & Power Districts left in the state.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Kennebunk — not a national franchise. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. That is how we keep customers calling back, one honest job at a time.
How Your Electrical Panel Works
- Meter — measures the power the utility delivers
- Main breaker — the single shutoff for the whole panel
- Branch breakers — one per circuit, trip on overload or a fault
- Neutral / ground bus — the common return and safety path
- Panel capacity — how much headroom is left for new circuits

Panel Upgrades: What Southern Maine Homeowners Should Know
Most electrical panel calls we get start the same way: a homeowner wants an EV charger, a heat pump, or a hot tub, and the panel that came with the house has nothing left to give. Here's the background we'd want you to have before that conversation with an electrician.

Codes & Permits for Panel Upgrades in Kennebunk
Electrical work in Kennebunk is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Kennebunk processes electrical permits locally through its Code Enforcement Office (Code Enforcement Officer Frank Kunkel and Assistant CEO Dylan Muldowney), though the town's public staff directory does not list a separately named 'Electrical Inspector' position — it's unclear from public sources whether inspections are performed by the CEO/Assistant CEO or a contracted inspector. Maine's Mandatory Shoreland Zoning Act applies along the Kennebunk and Mousam Rivers and Kennebunk's Atlantic coastline (Kennebunk Beach, Gooch's Beach, Mother's Beach), restricting structure placement near the water.
- A panel or service change is not 'minor repair work' under the state permit exemption (which covers only things like fuse/lamp/fixture/switch/socket/outlet replacement and entrance-service repair) — it requires the standard electrical permit, issued either by the Electricians' Examining Board or by a municipality with its own electrical inspector. maine.gov
- South Portland's Code Enforcement office states: 'If you are replacing or adding a service, you must provide the CMP work order number when applying for your permit,' and that 'Only electricians with a valid State of Maine electrician's license may take out electrical permits and do new electrical wiring in the City of South Portland.' southportland.org
- The Town of Eliot's current permit-process notice describes the electrician-to-utility energization step directly: the town used to notify CMP that a service was authorized to be energized, but 'the responsible Master or Limited Electrician will [now] provide the required documentation directly to the utility using Form 1360' before CMP will energize a new or altered service. source
- The Electricians' Examining Board operates within Maine's Office of Professional and Occupational Regulation (Department of Professional and Financial Regulation); it is the state body that adopts the NEC edition, licenses electricians, and issues the statewide electrical permit. maine.gov
How Aces Highlands Handles Panel Upgrades in Kennebunk
- Panel and service changes fall outside Maine's minor-repair exemption entirely — we pull the standard electrical permit on every one, no exceptions.
- Primarily Central Maine Power (CMP); the Kennebunk Light & Power District (KLPD), a municipal utility, serves portions of Kennebunk (plus parts of Wells, Arundel and Lyman). has to be looped in on most upgrades — a service change usually means a work order and, for a bigger jump in capacity, a scheduled disconnect/reconnect on their end.
- We wire and label the new panel to the 2026 National Electrical Code — the edition Maine adopted for anything installed from July 1, 2026 on.

I've had an excellent experience working with them for both electrical and HVAC work as I remodel my 1785 home. I highly recommend them.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.

I've had three HVAC issues over the past two years. Each time I call, Elija or the office picks up the phone, and my problem is fixed in 24 hrs. Their solutions always feel correct and honest. I cannot recommend them more.

Elijah and Highlands Heating & AC were super helpful! Boiler failed over the weekend and Elijah was very responsive and helpful, getting us up and running right away. I would recommend him at HH&AC highly!

We highly recommend Highlands Heating & AC. They are extremely responsive, knowledgeable and do great work. Our boiler stopped working and Elijah was quick to respond after hours on a Friday. He installed a new boiler and heat pump hot water heater.
Panel Upgrades FAQs
How long does an electrical panel upgrade take?
Most 100-to-200-amp upgrades are completed in a single day. Your power is off for a portion of that day while we swap the panel and coordinate the disconnect and reconnect with Central Maine Power — we schedule it to keep your downtime to a few hours.
Do I need a permit for a panel upgrade in Maine?
Yes. Panel and service upgrades require an electrical permit and municipal inspection. We pull the permit, schedule the inspection, and handle the utility coordination as part of every job — you do not have to manage any of it.
Why do Federal Pacific and Zinsco panels need to be replaced?
Breakers in FPE Stab-Lok and Zinsco panels have a documented history of failing to trip during a fault, which is a genuine fire hazard. Many Maine insurers now require replacement before issuing or renewing a homeowner policy. If you have one, replacement is a safety priority, not an upsell.
Do I really need 200 amps, or is that an upsell?
It depends on your loads. If you plan to add an EV charger, heat pump, or electric range, 200 amps is the practical standard. If your 100-amp service comfortably covers your actual usage and no additions are planned, we will tell you it is fine — our electricians are not commissioned salespeople.
Will a panel upgrade fix my flickering lights and tripping breakers?
Often, yes — those are classic symptoms of an overloaded or failing panel. But they can also come from a loose connection or a single overloaded circuit, which is a much smaller fix. We diagnose the actual cause first and quote you for what you need.
