Your electrical panel is the heart of your home's electrical system — it takes incoming power from the utility and distributes it safely to every circuit. When a panel is undersized, outdated, or failing, the warning signs are usually there long before something goes wrong. Knowing what to look for can save you from nuisance outages, damaged appliances, and in the worst cases, an electrical fire.

Many homes across Clark County, WA were built decades ago on 100-amp service or older fuse panels that simply weren't designed for today's electrical demand. Below are the seven most common signs our licensed electricians see when a panel is ready for an upgrade.

1. Your breakers trip frequently

An occasional tripped breaker is normal — that's the breaker doing its job. But if you're constantly resetting breakers, especially when you run everyday appliances, your panel may be overloaded or its breakers may be wearing out. Frequent tripping is one of the clearest signals that your electrical demand has outgrown your current service.

If your home still has a fuse box rather than circuit breakers, that's an even stronger indicator. Fuse panels are common in older homes and are generally undersized for modern living.

2. Lights dim or flicker when appliances turn on

If your lights dim when the air conditioner, microwave, or dryer kicks on, your panel is struggling to deliver enough power to everything at once. Momentary flickering across the whole house — not just one fixture — often points to an overloaded panel or a loose service connection that needs a professional's attention.

3. The panel is full — no room for new circuits

Open a typical panel and you'll see rows of breakers. When every slot is occupied, there's no room to safely add circuits for a new appliance, a remodeled kitchen, or a finished garage. "Tandem" breakers crammed into a full panel are a common workaround that can push a panel beyond its rated capacity. If your panel is maxed out, an upgrade gives you the headroom to grow.

4. You have an outdated or recalled panel

Certain panel brands installed in older homes have well-documented safety concerns. Federal Pacific (Stab-Lok) and Zinsco panels, in particular, have been associated with breakers that may fail to trip during a fault — meaning they can leave a circuit energized when it should shut off. If you have one of these panels, it's worth having a licensed electrician evaluate it.

5. You're adding a major electrical load

Modern upgrades draw serious power. If you're planning any of the following, your existing service may not be able to handle the added load:

Upgrading to 200-amp service is the modern standard and provides the capacity these loads require.

6. The panel feels warm, smells burnt, or shows scorching

This one is urgent. A panel that is warm to the touch, that gives off a burning or "fishy" plastic smell, or that shows any rust, scorch marks, or discoloration around the breakers can indicate loose connections or arcing — both serious fire hazards. If you notice any of these signs, stop using the affected circuits and call a licensed electrician right away.

7. Your home still runs on 100-amp (or less) service

Many older Clark County homes were built with 100-amp service, and some even less. That may have been plenty in its day, but it leaves little margin for today's appliances and electronics. If you're not sure what service your home has, the main breaker in your panel is usually labeled with its amperage — or a quick visit from an electrician will confirm it.

What a panel upgrade involves

A panel upgrade replaces your existing service panel — and often the meter base and main breaker — with a higher-capacity, code-compliant system. In Washington State, panel and service upgrades require an electrical permit, and the work follows the 2023 National Electrical Code (NEC), which Washington has adopted with expanded GFCI, AFCI, and outdoor emergency-disconnect requirements.

When Crown Electric handles your upgrade, we pull the permit, coordinate the utility disconnect and reconnect, complete the installation — usually in a single day — and schedule the inspection so your new service is fully documented and compliant.

Don't ignore the warning signs

One of these signs on its own may be minor; several together usually mean it's time to act. An aging or overloaded panel won't fix itself, and the risks — nuisance outages, damaged equipment, and fire — only grow over time. If anything in this list sounds familiar, the safest next step is a professional evaluation.
