Panel Upgrades for Wells Homeowners
100 to 200-Amp Upgrades
Breaker Replacement
Code Compliance
For panel upgrades in Wells, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from York County and already familiar with the homes, climate and codes here.
An outdated or undersized electrical panel can be a safety hazard and limit what your home can handle.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Many older homes in the Portland area still have 100-amp panels or outdated fuse boxes that cannot support modern electrical loads.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 While the panel is open, it is also the right time to address any outdated wiring in your home.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.

Wells Homes and What They Need
Wells has one of the newest housing stocks among the York County coastal towns Aces serves, with a median build year of 1989 and only about 8 percent of homes predating 1940. That postwar-and-later coastal development boom means most of the systems we work on here are second- or third-generation, not original construction. Heat pump repair on those newer systems is a common call.
Power, Storms and Wiring in Wells
Central Maine Power serves Wells, with no municipal electric utility operating in town. On the beach-neighborhood homes especially, ongoing salt exposure makes panel upgrades and corrosion-resistant fittings a bigger part of the job than they would be further inland.
Getting to Know Wells
Wells was founded in 1643 and incorporated on July 5, 1653, making it the third town incorporated in Maine. The town is drained by the Webhannet River and is home to both the Wells National Estuarine Research Reserve at Laudholm Farm and the Rachel Carson National Wildlife Refuge.
Of the town's 73.6 square miles, more than 16 are water, reflecting Wells' extensive beach and marsh frontage across four distinct beach neighborhoods: Wells Beach, Moody Beach, Drakes Island Beach, and East Shore Beach.
Local & Independent — Not a Franchise
Aces Highlands answers to Wells homeowners directly, not a franchise office somewhere else in the country. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. Getting invited back is the only metric that matters here.
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 Wells
Electrical work in Wells is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Wells has no municipal electrical inspector; the Code Enforcement Office directs electrical questions to the Maine State Electrical Inspector (207-592-7930) — i.e. the State of Maine electrical inspection program (Office of Professional & Occupational Regulation / Electricians' Examining Board). A separate water utility (KKW) and sanitary/sewer district (Wells Sanitary District) serve the town rather than one combined utility.
- 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
- Maine's 2026 NEC amendments in Chapter 120 do not touch NEC Article 230.67 (the national requirement for surge-protective devices on new or replaced dwelling-unit services) or Article 220 (the standard load-calculation methods); both apply in Maine exactly as published in the 2026 NEC. maine.gov
- Chapter 120 does amend NEC 230.4(E): where a building is supplied by more than one service (or a combination of branch circuits, feeders and services), Maine requires 'a permanent plaque or directory' at each service disconnect location and each outside meter location identifying all other services/feeders/branch circuits and the area each one serves. maine.gov
- Central Maine Power (CMP), a subsidiary of Avangrid, describes itself as serving 'approximately 670,520 electricity customers in an 11,000 square-mile service area in central and southern Maine' — the region that contains the entire Augusta-to-York corridor. Consistent with this, South Portland's own permitting page requires a CMP account/work-order number on any electrical permit tied to a service change, and Buxton's electrical permit application has a dedicated field for the applicant's CMP account number. cmpco.com
How Aces Highlands Handles Panel Upgrades in Wells
- A service or panel change is never "minor repair work" under Maine's permit exemption, so it always gets a full electrical permit before we open the panel.
- Central Maine Power (CMP) 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 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.

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.
