What to do if…
you hear buzzing or crackling from your electrical panel or fuse box

Short answer

Buzzing or crackling from a breaker panel can indicate arcing/overheating. If it’s safe, turn off the main breaker and call a licensed electrician urgently; if you see smoke/flames or smell strong burning, evacuate and call 911.

Do not do these things

  • Do not open the panel door/cover or touch anything inside.
  • Do not keep resetting breakers to “test” it.
  • Do not touch the panel if it’s hot, if you see scorch marks/melting, or if there’s smoke/sparking.
  • Do not use water to put out an electrical fire.
  • Do not assume it’s harmless because power is still on.

What to do now

  1. Do a quick danger check: Do you see smoke, sparks, flames, or smell a strong burning/plastic odor, or does the panel feel hot?
  2. If yes:
    • Get everyone outside and away from the building.
    • Call 911 and report a suspected electrical fire/electrical hazard.
    • Don’t go back in until responders say it’s safe.
  3. If no smoke/fire and you can reach the panel safely:
    • Switch OFF the main breaker to cut power to the home.
    • If you’re unsure which is the main breaker, don’t guess — step back and call for help.
  4. Keep the area clear: Keep people and pets away from the panel and any nearby outlets/switches that were acting oddly.
  5. Call a licensed electrician (urgent): Say you heard buzzing/crackling from the electrical panel and whether you shut off the main breaker.
  6. If the hazard seems tied to the utility service equipment (meter base, service drop, outdoor equipment) or you see damage outside:
    • Don’t touch it; keep your distance.
    • Call your electric utility’s emergency number. If it looks immediately dangerous (sparking/fire), call 911.
  7. Leave power OFF until it’s checked: Don’t restore power until an electrician (or the utility, if it’s their equipment) says it’s safe. If power is restored and the noise returns, turn it off again (if safe) and re-contact them.

What can wait

  • You do not need to identify the exact cause (loose connection, failing breaker, overloaded circuit, arc fault, etc.) right now.
  • You do not need to decide on a panel replacement or upgrade today.
  • You do not need to troubleshoot appliances one-by-one until a professional says the system is safe.

Important reassurance

A noisy panel is a valid reason to act quickly, and shutting power off is a protective step — it reduces the chance of escalation. Getting a licensed electrician involved is the normal, appropriate next move.

Scope note

These are first steps to reduce immediate risk. A licensed electrician (and sometimes the electric utility) needs to inspect and confirm what’s safe before power is restored.

Important note

This is general safety information, not electrical or legal advice. If there’s any sign of fire or you feel unsafe, prioritize evacuation and emergency services.
