Your home's electrical system works behind the scenes 24/7, powering everything from lighting and appliances to security systems and smart home technology. But when was the last time you actually assessed whether your electrical system is operating safely?
Most homeowners take electrical safety for granted until something goes wrong. However, electrical problems cause over 50,000 house fires annually in the United States, resulting in hundreds of deaths and billions in property damage. Many of these tragedies could be prevented with regular electrical safety assessments.
Use this comprehensive checklist to evaluate your home's electrical safety—and know when it's time to call a professional electrician.
Electrical Panel Safety Assessment

- Warm or hot panel surface when touched
- Buzzing, crackling, or sizzling sounds from the panel
Age and Brand Concerns:
- Is your electrical panel over 25 years old?
- Do you have a Federal Pacific or Zinsco panel? (These brands are known fire hazards)
- Are you still using an old fuse box instead of modern circuit breakers?
Capacity and Labeling:
- Are circuit breakers frequently tripping?
