Electrical Panel Upgrades in Rochester, NH

A few situations mean your panel isn't just inconvenient, it's a liability:

• Federal Pacific Stab-Lok panels: These were recalled decades ago for failing to trip during overloads. If you have one, it needs to go.
• Fuse boxes: Fuses were the standard before modern circuit breakers. They're not just outdated; they're a risk when homeowners replace blown fuses with the wrong amperage.
• Breakers that trip constantly: One or two trips a year on a heavy circuit is normal. Breakers tripping weekly, or a breaker that won't reset, means something is wrong with the panel or the circuit.
• Burning smell near the panel: Don't investigate this yourself. Call us.
• You're adding an EV charger or major appliance: Both require dedicated circuits and sometimes a full service upgrade to support the added load.
• Your home is over 40 years old, and the panel is original: Panels don't last forever. Most have a useful life of 25 to 40 years.

A panel upgrade is a permitted job in New Hampshire, and your municipality will require an inspection before the work is considered complete. We handle the permit application and schedule the inspection as part of the job. You don't have to manage that process yourself.

Most residential panel upgrades take between four and eight hours. Your home will be without power while the work is in progress, and it'll be back on before we leave. If there's additional wiring or a larger service change involved, we'll tell you upfront what the timeline looks like.

They're often used interchangeably. Technically, a service upgrade involves replacing the service entrance cable, the meter base, and the main panel, while a panel upgrade may just refer to replacing the breaker box itself. In practice, most older homes need both done at the same time. We'll assess your existing service entrance cable and let you know what's actually required versus what's optional.

Not always. A single breaker that trips regularly could mean a faulty breaker, a circuit that's overloaded, or a wiring issue upstream. A panel that's constantly tripping across multiple circuits is a different story. We can diagnose whether you're dealing with a single circuit problem or a panel that's hit its capacity.

Federal Pacific Electric made Stab-Lok panels from the 1950s through the 1980s. They were widely sold across the Northeast, and many are still in service in older homes in New Hampshire and Maine. The problem: the breakers fail to trip during overloads at a higher rate than standard panels. That means a breaker can look fine while a circuit overheats. If you have one, it doesn't mean your house is on fire today, but it does mean you're carrying a risk you don't have to carry. We replace Federal Pacific panels regularly across the Seacoast area, along with Zinsco panels, Pushmatic panels, and fuse boxes, to restore your home’s safety.

Yes, and we recommend it. If you're already upgrading your panel, adding a whole-home surge protector at the same time is efficient and cost-effective. It protects every circuit in your home from voltage spikes, including your HVAC system, appliances, and any smart home devices.

Panel upgrades often tie into other electrical work. Our team can handle the surrounding scope in the same visit or a follow-up appointment:

• Dedicated circuit installations: EV chargers, electric dryers, hot tubs, home offices, and kitchen appliances all need their own circuits. We install dedicated circuits for any application, with financing up to $2,500.
• EV charger installation: We install Level 2 home chargers for all major EV brands. Financing is available.
• Whole-home surge protection: Once your panel is upgraded, a whole-home surge protector installation is the next smart step. It protects every device on every circuit from voltage spikes.
• Circuit breaker troubleshooting and replacement: Not every panel needs a full upgrade. Sometimes a single failing breaker is the issue. We'll tell you which one applies to your situation.
• GFCI outlet installation: GFCI electrical outlets are required by code in bathrooms, kitchens, garages, and outdoor areas, and it's something we check during any panel work.
• Electrical wiring: If your home has knob and tube wiring or other outdated or damaged wiring, we'll handle the rewiring work alongside the panel upgrade.
• Electrical safety inspections: Not sure what shape your panel and wiring are in? An inspection gives you a full picture before you commit to anything.
