How to Know When Your Home Needs a Panel Upgrade (Evansville Guide)

If you live in one of Evansville's older neighborhoods — Jacobsville, Haynie's Corner, or the near east side — there's a good chance your home was built decades before modern electrical demands existed. Many houses in Vanderburgh County were constructed between 1940 and 1980, and their electrical panels were sized for a time when a television, a refrigerator, and a few lamps were the extent of household electricity use.

Today, the average household runs multiple TVs, central air conditioning, electric water heaters, EV chargers, home offices, and kitchen appliances that pull far more amperage than a 100-amp panel was ever designed to handle. Here's how to tell if your panel is overdue for an upgrade.

Signs Your Electrical Panel Needs Upgrading

The most common warning signs aren't subtle, but homeowners often dismiss them as normal quirks of an older home. They're not. They're indicators that your panel is struggling to keep up.

• Frequent breaker trips: If breakers trip regularly when you run the microwave and AC at the same time, your panel doesn't have enough capacity.
• Flickering or dimming lights: When lights dim as appliances kick on, the panel is redistributing power it doesn't have enough of.
• A burning smell near the panel: This is an immediate safety concern. Turn off the main breaker and call a licensed electrician right away.
• Warm or discolored panel cover: Heat buildup inside the panel means connections are degrading or breakers are failing.
• Two-prong outlets throughout the home: This indicates ungrounded wiring, which often coincides with an outdated panel that lacks GFCI/AFCI protection.
• Your panel is a fuse box: If your home still uses screw-in fuses instead of breakers, it's well past time. Insurance companies in Indiana increasingly refuse to renew policies on homes with fuse boxes.

Panel Age Matters More Than You Think

Electrical panels have a functional lifespan of roughly 25 to 40 years. Evansville has a large stock of homes built during the post-war boom of the 1950s and 60s, meaning many panels are now 50 to 70 years old. Even panels installed in the 1980s are approaching or past their useful life.

Certain panel brands have known failure issues. If your home has a Federal Pacific Electric (FPE) Stab-Lok panel or a Zinsco panel, these should be replaced regardless of whether you're experiencing problems. Both brands have documented failure rates that create fire hazards. These panels were commonly installed in Evansville homes built or remodeled between 1950 and 1980.

What Size Panel Do You Need?

Most modern Evansville homes benefit from a 200-amp panel, which provides enough headroom for central air conditioning, an electric range, a water heater, and general household circuits without running near capacity. If you're planning to add any of the following, 200 amps should be your minimum:

• An EV charging station
• A tankless electric water heater
• A finished basement or room addition
• A heat pump HVAC system

For smaller homes — under 1,200 square feet with gas appliances — a 150-amp panel may be sufficient. But upgrading to 200 amps gives you future flexibility and costs only slightly more.

Indiana Code and Permitting

In Indiana, panel upgrades must comply with the current Indiana Electrical Code, which is based on the National Electrical Code (NEC). The 2023 NEC cycle requires:

• AFCI (arc-fault circuit interrupter) protection on most living-area circuits
• GFCI protection on kitchen, bathroom, garage, and outdoor circuits
• Proper grounding and bonding of the electrical service
• Surge protection at the service entrance (recommended, not always required)

A panel upgrade in Evansville requires an electrical permit from the Vanderburgh County Building Commission. The work must be performed by a licensed electrician and will be inspected. If a homeowner attempts a panel swap without a permit and inspection, it can create problems when selling the home or filing an insurance claim after a fire.

What to Expect During a Panel Upgrade

A standard panel replacement takes between 4 and 8 hours. The power will be off for most of that time. Here's what the process typically involves:

1. The electrician pulls a permit and schedules the utility company to disconnect power.
2. The old panel is removed and the new panel is mounted.
3. Circuits are reconnected, with new breakers installed that meet current code.
4. Grounding and bonding are updated as needed.
5. The building inspector signs off on the installation.
6. Power is restored.

If your service entrance cable is undersized or your meter base is outdated, those may need upgrading at the same time, which adds to the cost and timeline.

Don't Wait for a Failure

The most expensive panel upgrade is the one that happens after a fire. If your panel is over 30 years old, showing warning signs, or still using fuses, schedule an inspection with a licensed Evansville electrician. A panel assessment is inexpensive, and it gives you a clear picture of whether your electrical system can handle what your family needs it to do today — not what it needed to do in 1965.
