Your electrical panel works silently in the background, distributing power throughout your home 24/7. While panels are designed to be reliable, regular maintenance can identify problems before they become emergencies, extend your panel's lifespan, and ensure your family's safety.
Key Takeaways
- Inspect your panel exterior monthly for signs of damage, corrosion, or unusual sounds.
- Test GFCI and AFCI breakers quarterly using the built-in test buttons.
- Keep 3 feet of clear space in front of the panel at all times for emergency access.
- Schedule a professional panel inspection every 3-5 years, or annually for panels over 25 years old.
Homeowner Maintenance: You can safely inspect the panel exterior, test GFCI/AFCI breakers using test buttons, and check circuit labels. Never remove the interior panel cover or touch wires -- leave that to licensed electricians.
