Your electrical panel is the heart of your home’s wiring, and most homeowners never think about it until something goes wrong. Across Wakefield, the Lakes Region and southern Maine, we see a lot of older homes and camps still running on panels that were installed decades ago, long before heat pumps, EV chargers and home offices. Here are the signs it’s time for an upgrade, and what it typically costs.
7 signs your panel needs an upgrade
1. Breakers trip often
A breaker that trips once in a while is doing its job. A breaker that trips every time you run the microwave and the toaster together is telling you that circuit, or the whole panel, is overloaded. Constant tripping is one of the most common reasons homeowners call us.
2. You still have fuses
Fuse boxes were standard decades ago, and many are still in service in older New Hampshire homes. They aren’t automatically dangerous, but they usually mean a 60-amp or 100-amp service that can’t keep up with modern loads. Some insurance companies also charge more for, or won’t cover, homes with fuse panels.
3. Your panel is a known problem brand
Certain panels from the 1950s through the 1980s, including Federal Pacific Stab-Lok and Zinsco, have a history of breakers that fail to trip when they should. If you see either name on your panel door, it’s worth having it looked at, even if everything seems fine.
4. Lights dim or flicker
If your lights dim when the well pump, furnace or a big appliance kicks on, your service may be undersized or a connection may be loose. Either way, it’s worth a look.
5. Warm panel, burning smell or buzzing
A panel cover that’s warm to the touch, a burning smell, scorch marks or a buzzing sound are warning signs. These point to overheating connections and should be checked right away. If you smell burning, shut off the main breaker if it’s safe to do so and call an electrician.
6. You’re out of breaker space
If your panel is full and you’ve been relying on tandem breakers or power strips everywhere, you’ve outgrown it. A new panel gives you room for the circuits you need now and later.
7. You’re adding a big load
Planning a heat pump, EV charger, standby generator, hot tub, addition or kitchen remodel? Many of these need more capacity than a 100-amp service can safely provide. Upgrading the panel first saves headaches later, and it’s often required to pass inspection.
Panel replacement vs. service upgrade: what’s the difference?
A panel replacement swaps out the breaker box itself while keeping the same amperage. It’s the right call when the panel is old, damaged or a problem brand, but your capacity is fine.
A service upgrade increases the capacity coming into your home, typically from 100 amps to 200 amps. That usually means a new meter socket, new service entrance cable and a new panel, plus coordination with your utility (Eversource, NH Electric Co-op or Central Maine Power, depending on where you are) to disconnect and reconnect power.
What does a panel upgrade cost in NH?
Here are our typical price ranges. Every home is different, so we’ll give you a firm quote after seeing your setup.
- Panel replacement (up to 200 amps): $1,200–$2,300, usually done in 4–8 hours
- Service upgrade (100 to 200 amps): $3,000–$5,000, usually 1–2 days, including permits and utility coordination
- Full service replacement (utility connection to panel): $2,200–$5,500, usually 1–2 days
What moves the price: how far the meter is from the panel, whether the service is overhead or underground, the condition of the existing wiring and grounding, and any code updates required during inspection. You can see more of our typical prices on our pricing page.
Do I need a permit?
In most New Hampshire and Maine towns, yes. Some smaller towns don’t have a building department, but where one exists, panel and service work generally requires an electrical permit and inspection, and the utility will want the work done by a licensed electrician before they reconnect power. We handle the permit and the utility scheduling for you.
What to expect on upgrade day
For most panel replacements, your power is off for part of one day. Service upgrades can take a bit longer, depending on when the utility can reconnect. We’ll tell you the plan ahead of time, label the circuits in the new panel as accurately as we can (in older homes, circuits often were never labeled, or were labeled wrong) and clean up when we’re done. Every job is backed by our lifetime workmanship warranty.
