Panel Upgrades for Kittery Homeowners

Kittery sits in York County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for panel upgrades gets a technician who already knows the local housing and codes, not a first-timer.
An outdated or undersized electrical panel can be a safety hazard and limit what your home can handle.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Many older homes in the Portland area still have 100-amp panels or outdated fuse boxes that cannot support modern electrical loads.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 While the panel is open, it is also the right time to address any outdated wiring in your home.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.

Kittery Homes and What They Need
Kittery has the oldest housing stock of the York County coastal towns Aces serves, with a median build year of 1965 and about 25 percent of homes predating 1940 (46 percent predating 1960) -- fitting for a town that has been incorporated since 1647. On homes this old, a rewiring project often turns up several generations of electrical work layered on top of each other.
Power, Storms and Wiring in Kittery
Central Maine Power serves Kittery, with no municipal electric utility in town. Given how much of Kittery's housing predates 1960, older panels and knob-and-tube wiring are a routine find, and panel upgrades are frequently the first step before adding a heat pump or EV charger.

Getting to Know Kittery
Kittery was incorporated in 1647, making it the oldest incorporated town in Maine, and sits as the state's southernmost town, across the Piscataqua River from Portsmouth, New Hampshire. The Portsmouth Naval Shipyard, established in 1800 on Kittery's Seavey's Island, was the U.S. Navy's very first federal navy yard.
During the Revolutionary War, some of the first vessels ever built for the U.S. Navy, including the USS Ranger under John Paul Jones, were constructed right on Kittery's Badger's Island -- a history that still shapes the town's identity along the water.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Kittery gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. We show up, fix the actual problem, and let the work speak for itself.
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 Kittery
Electrical work in Kittery is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Kittery's Code Enforcement Department issues electrical permits directly ($30 base fee) under the National Electrical Code; code compliance is certified by the installing Maine-licensed electrician via a signed Electrical Installation Code Compliance Affidavit, and no separate municipal field inspector is named — it is unconfirmed whether inspection defaults to the State of Maine electrical inspection program. The Portsmouth Naval Shipyard occupies Seavey's Island within Kittery's boundaries and is a major regional employer.
- 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
- 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
- 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 Kittery
- Panel and service changes fall outside Maine's minor-repair exemption entirely — we pull the standard electrical permit on every one, no exceptions.
- Because Central Maine Power (CMP) owns the service drop, we coordinate the work order and any disconnect/reconnect with them before your new panel goes live.
- The finished panel is built and inspected to the 2026 NEC, the edition Maine has required for every installation starting July 1, 2026.

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 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!

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.
