Electrical Panel Upgrades in Windham & Southern Maine

If your home is more than 20 years old, you’ve been tripping breakers, or you’re adding an EV charger or heat pump, it may be time for an electrical panel upgrade. Peak Electric is Windham’s trusted licensed electrician for panel replacements, 200-amp service upgrades, and breaker box work throughout Southern Maine. We handle the full job — permit included — so you don’t have to worry about the details.

What Is an Electrical Panel Upgrade?

Your electrical panel — also called a breaker box or load center — is the hub that distributes electricity throughout your home. When you flip on a light or plug in an appliance, it's your panel that controls how much power flows to each circuit.

Most Maine homes built before 2000 came with 100-amp service — enough for the appliances and electronics of that era, but often undersized for today's loads. Modern homes with EV chargers, mini-split heat pumps, electric ranges, and home offices may need 200-amp service or more to run safely and efficiently.

In older Maine homes, panel upgrades often involve replacing Federal Pacific Stab-Lok or Zinsco panels — brands known for safety issues and unreliable breaker performance. Replacing these panels isn't just about capacity — it's about peace of mind.

Signs Your Home May Need a Panel Upgrade

If any of the following sound familiar, your electrical system may be telling you something:

Breakers that trip regularly, especially on specific circuits

Lights that flicker or dim when large appliances run

A burning smell near the electrical panel

Outlets or switches that feel warm to the touch

A panel with only 100-amp service in a home with modern loads

Federal Pacific Stab-Lok or Zinsco brand panel

No ground fault (GFCI) or arc fault (AFCI) protection

These aren't just inconveniences — they can be early warning signs of a system under stress. A licensed electrician can assess your panel and tell you whether an upgrade is needed.You're planning a major addition, EV charger, or heat pump installation

What's Included in a Peak Electric Panel Upgrade

Every panel upgrade we complete includes:

• Removal and disposal of your old electrical panel

• Installation of a new code-compliant load center

• 200-amp service upgrade (in most cases)

• Permit application and inspection coordination

• CMP (Central Maine Power) coordination

• Grounding and bonding to current code

• Full circuit labeling and testing

We don't cut corners. Every job is done to code, on budget, and backed by our workmanship guarantee.

Panel Upgrades for EV Chargers, Heat Pumps & Smart Home Systems

Modern homes need more power than older panels were built to handle. If you're adding an EV charger, mini-split heat pump, whole-home generator, or smart electrical system, your existing panel may not have the capacity to support it safely.

Peak Electric works with homeowners throughout Windham and Southern Maine to size and install panels that support today's electrical demands. We coordinate with your equipment installer or general contractor to make sure everything is ready before install day.

Whether you need a 200-amp upgrade or a subpanel added for a garage or addition, we'll make sure your home is wired right the first time.
