Why Insurance Companies Are Flagging Panels

Electrical panels are a leading contributor to residential fire risk. Certain older or defective panel designs have documented histories of breaker failure, overheating, or inability to shut power off during a fault. As a result, insurers now require stricter compliance and documentation.

Panels Most Likely to Fail an Insurance Review

Zinsco / GTE-Sylvania

Breakers may fail to trip and overheat at the bus bar.

Federal Pacific (FPE) Stab-Lok

Widely documented failure to disconnect during faults.

Pushmatic panels

Known issues with breaker overheating and loose connections.

Or any panels with missing manufacturer labels or evidence of unpermitted work.

Frequently Asked Questions (FAQs)

How do I know if I need to upgrade my panel or fuse box?

It may be time for a panel upgrade if your breakers trip frequently or you still have an older fuse box, which isn’t built to handle today’s electrical loads. Flickering or dimming lights, a panel with no available breaker spaces, or plans to add equipment like an EV charger, hot tub, solar panels, or other large appliances are all good reasons to have your panel evaluated.

Why is my panel or breaker box sparking?

Sparking at the panel can stem from a loose light bulb or faulty switch elsewhere in a circuit, a loose electrical connection, moisture or water intrusion, damaged wiring, or an aging and obsolete panel that’s no longer safe for today’s electrical loads. Sparking at the panel is a serious safety concern, so avoid touching the panel and contact a licensed electrician right away.

Do I need a new panel if I’m installing solar?

You likely don’t need a new panel if your existing one is 200 amps and in good condition, there’s enough capacity under electrical code to add a solar back fed breaker, and the panel has available breaker spaces or can accommodate tandem breakers where permitted. Your existing panel should also be from a reputable manufacturer and not obsolete or subject to a recall.

How do I know if I need to upgrade my panel for an EV charger?

You may need a panel upgrade if your home has 100 amp service along with several large electrical loads, such as central air conditioning, an electric water heater, an electric range, an electric dryer, pool or spa equipment, or solar with battery storage. A panel that’s full with no available breaker spaces, an electrical load calculation showing insufficient capacity, an older or obsolete panel, or plans for additional electrification like a heat pump, induction range, or another EV charger are all signs an upgrade may be needed.
