Upgrading Your Main Electrical Panel to 200 Amps
Your electrical panel is the central distribution point for all electricity in your home. Many homes in the Statesville and Mooresville areas still operate on outdated 100-Amp or 150-Amp services. While these were sufficient decades ago, modern demands like Level 2 EV charging, central heat pumps, hot tubs, and generator connections require increased capacity.
Upgrading to a 200-Amp service provides safety, prevents breaker overloads, and guarantees that your electrical system complies with modern code.
When is it Time to Replace or Upgrade Your Panel?
- Documented Safety Hazards: If your home has a Federal Pacific Electric (FPE) Stab-Lok or Zinsco panel, we recommend immediate replacement. These brands have documented design flaws where breakers fail to trip during overloads, creating severe fire hazards. Many insurance companies will deny coverage until these are replaced.
- Frequent Breaker Trips: If your breakers trip regularly when using kitchen appliances, hair dryers, or space heaters, your circuits are overloaded.
- Physical Symptoms of Wear: Buzzing, sizzling, or crackling noises from the panel, or breaker switches that feel loose or warm to the touch, indicate loose terminations or decaying busbars.
- Adding Modern Equipment: Installing a Level 2 EV charger, a backup generator transfer switch, or a ductless mini-split HVAC system usually requires upgrading your service capacity.
The Upgrades Process and Duke Energy Coordination
A panel upgrade is not a simple DIY project. Under North Carolina law, it requires a licensed electrical contractor to obtain municipal permits and coordinate with the utility provider.
- Duke Energy Disconnect: We coordinate with Duke Energy to shut off power at the street or service drop on the morning of the job.
- Service Mast & Meter Installation: We remove the outdated box and replace the exterior service mast, meter base, grounding rods (two copper rods driven to code), and the interior panel box.
- Circuit Mapping & Labeling: We feed your existing branch circuits into the new panel, installing modern AFCI/GFCI breakers as required by NEC safety codes, and completely label each circuit.
- Local Inspection & Reconnection: The local city or county inspector inspects the installation. Once approved, Duke Energy restores power, typically within a 4 to 8-hour total downtime window.

Frequently Asked Questions
How do I know if my electrical panel needs an upgrade?
Common warning signs include breakers that trip frequently, crackling sounds from the panel, warm panel surfaces, or if your home still uses old screw-in fuses. Furthermore, if you are adding major appliances like an EV charger or heat pump, a 200-Amp upgrade is highly recommended.
How long does an electrical panel upgrade take?
A standard panel upgrade takes about 4 to 8 hours. During this window, the power to your home will be temporarily disconnected. We coordinate closely with Duke Energy to ensure power is restored as quickly and safely as possible.
Is it safe to keep a Federal Pacific or Zinsco panel in my home?
No. Federal Pacific (FPE) and Zinsco panels have documented design flaws where breakers fail to trip during an overload, leading to electrical fires. Insurance companies frequently require their replacement, and we recommend upgrading them immediately.
Do I need a licensed electrician for electrical panel upgrades?
Yes, electrical work should be handled by a qualified licensed electrician when safety, wiring, panels, circuits, or permanent installation are involved. Mills Electric Co. is licensed under Electrical License #36565 and carries insurance through biBerk Policy #N9BP158903. A licensed contractor can also help you avoid unsafe shortcuts that may create problems later.
How do I know if I need electrical panel upgrades or a different electrical service?
You do not have to diagnose it before calling. Explain what you are seeing, hearing, smelling, or planning. Mills Electric Co. will look at the affected circuit, panel, device, or fixture and recommend the service that actually matches the issue.
Can Mills Electric Co. provide a price before starting?
For many jobs, pricing can be discussed after the scope is reviewed. Electrical pricing depends on access, materials, panel condition, circuit length, device type, and safety requirements. The goal is to be clear before the work moves forward, not surprise you at the end.
Is electrical panel upgrades covered by a warranty?
Mills Electric Co. provides a 1 year workmanship warranty. Extended workmanship warranty coverage is available at 10% of the job cost per additional year, up to 5 years. Product warranties may depend on the manufacturer.
Can this be scheduled outside normal business hours?
Some service can be planned around access needs, and urgent issues may fall under emergency service. If the situation involves sparking, burning smells, heat at the panel, exposed live wiring, or power loss affecting safety, call (704) 818-7867.
Will the work be explained before anything is replaced?
Yes. Raymond Mills believes customers should understand the reason behind the recommendation. When troubleshooting or inspecting, the goal is to identify the cause before replacing parts that may not solve the problem.
