How often should electrical panels be inspected for safety?

Electrical panels should be inspected on a periodic schedule by a licensed electrician, with the interval set by your home’s age, panel condition, and any changes in electrical load. The most common driver for more frequent checks is added circuits or wear that loosens connections over time, which can create heat and nuisance tripping. After an initial safety inspection, a pro can recommend a sensible cadence; minor issues like loose lugs are usually repaired on the spot, while signs of overheating, corrosion, or obsolete equipment point to repair or panel replacement. Our electricians routinely perform these panel checks for homeowners in the Cottage Grove area.

Consider scheduling an inspection if you notice any of the following:

• Breakers that trip often or won’t reset
• Lights that flicker or dim when appliances start
• Warm or buzzing panel, rust, or a burning odor
• Recent renovation, DIY wiring, or a major storm/surge event

If you notice heat, burning odor, or visible arcing at the panel, stop using affected circuits and call a licensed electrician immediately.
