Signs Your Electrical Panel Needs an Upgrade (Don't Ignore These)

Your electrical panel is the heart of your home's power system. When it starts failing, you'll notice. Here are the warning signs.

1. Breakers Trip Constantly

If you're resetting breakers regularly, that circuit is consistently handling more load than it was designed for — a symptom of an undersized panel. Think of a breaker as a safety valve: it trips to protect your wiring from overheating. When it trips often, it's telling you the system is being pushed beyond its safe limits. Ignoring it doesn't fix the problem — it just silences the warning.

2. You Have a Fuse Box Instead of Breakers

Most insurance companies in NH and Maine will refuse to insure a home with a fuse panel, or charge significantly higher premiums. Fuse boxes were designed for homes with far fewer electrical demands than we have today — no EV chargers, no smart devices, no central AC. A modern breaker panel isn't a luxury upgrade; for many insurers, it's a requirement to get coverage.

3. Lights Flicker or Dim

Persistent flickering — especially across multiple rooms — can indicate an overloaded panel struggling to deliver consistent voltage. Beyond being annoying, inconsistent voltage can silently damage appliances and sensitive electronics over time. In more serious cases, the underlying cause is a fire risk that deserves a professional evaluation.

4. You're Adding Major Appliances or an EV Charger

Hot tubs, EV chargers, central AC — these all draw significantly more power than typical household circuits. If your home is on 100-amp service, adding one of these can push the panel past its safe operating point. A 200-amp upgrade gives your home the headroom to handle modern demands without strain.

What Does a Panel Upgrade Cost?

The cost varies based on your home's current service size, the complexity of the work involved, and your town's permit fees. No two jobs are exactly alike, so we evaluate each situation individually and give you a clear picture of what's needed before any work begins. We're licensed in both NH and Maine and serve homeowners throughout Dover, Portsmouth, Exeter, Rochester, Somersworth, and the Seacoast — including South Berwick, Kittery, and York.
