How Often Should Your Electrical Panel Be Inspected?

The general guideline

A professional inspection every 3 to 5 years is reasonable for most homes, and it's a standard part of most home inspections when buying or selling. Homes over 25 to 30 years old, or with any history of DIY electrical work, benefit from more frequent attention.

Signs that warrant an inspection sooner

• Breakers that trip repeatedly without an obvious cause
• A panel that feels warm to the touch or has a burning smell nearby
• Visible rust, corrosion, or water staining on or near the panel
• Buzzing or crackling sounds from the panel
• You're adding a major new appliance (EV charger, hot tub, workshop equipment)

Panel brands and types worth knowing about

Certain older panel brands and types (some Federal Pacific and Zinsco panels, in particular) have well-documented histories of failing to trip properly under fault conditions. If your home has an older panel, it's worth having an electrician confirm what you have and whether it's a known concern — this is exactly the kind of thing worth knowing before it becomes urgent, not after.

Why this one shouldn't wait

Unlike a lot of home maintenance, electrical panel issues don't always announce themselves with a clear symptom before they become a genuine safety issue. This is one of the few items worth being proactive about rather than reactive.
