Burning Smell from Electrical Panel — What to Do Right Now
A burning smell from your electrical panel is an emergency. Here's what to do immediately, what causes it, and when your panel needs to be replaced.
This is not a "schedule it next week" situation. A burning smell from your panel means something is actively overheating inside your breaker box. Here's exactly what to do.
What to Do Right Now
- Turn off the main breaker — the large breaker at the top (or bottom) of your panel. This de-energizes every circuit in your home.
- Do NOT open the panel cover — if there's active arcing or melting inside, opening the cover exposes you to the hazard.
- Do NOT touch individual breakers — a melting bus bar or arcing connection can energize the panel cover and breaker handles.
- Move your family away from the panel area.
- If you see flames, smoke, or the smell is intense → Call 911 first, then call an electrician.
- If the smell is present but no visible fire → Call a licensed electrician for emergency service.
What Causes a Burning Smell
Loose connections: The #1 cause. A wire that's not tightly connected to its breaker or the neutral/ground bus generates resistance. Resistance creates heat. Heat melts insulation. Melting insulation produces the burning smell.
Overloaded breaker: A breaker carrying more current than it's rated for generates excess heat. If the breaker fails to trip (common in older or defective breakers), the heat builds until insulation melts.
Corroded bus bar: The bus bar is the copper or aluminum strip inside your panel that distributes power to each breaker. Corrosion (from moisture, age, or poor installation) increases resistance and generates heat at the connection points.
Double-tapped breakers: Two wires on a single-pole breaker rated for one wire. The connection is loose by definition and generates heat.
Failed breaker: Breakers have internal components that can degrade over time. A failed breaker may draw current through a partial connection — creating intense localized heat.
Federal Pacific / Zinsco panels: These recalled panel brands have a documented history of breakers failing to trip and bus bar connections overheating. If you have one of these brands and smell burning, replacement is not optional.
What the Electrician Will Do
During an emergency panel inspection, we:
- Verify the panel is de-energized
- Remove the panel cover and inspect every connection, breaker, and the bus bar
- Identify the source of the overheating
- Photograph the damage for your records (and insurance if applicable)
- Repair or replace the affected components — or recommend full panel replacement if the damage is extensive
When the Panel Needs Replacement
If the burning smell was caused by:
- A corroded or damaged bus bar → panel replacement
- A Federal Pacific or Zinsco panel → panel replacement
- Multiple failing breakers → likely panel replacement
- A single loose connection or one bad breaker → repair, not replacement
A 200-amp panel replacement in Kansas City typically costs $1,500–$3,500+. Insurance may cover the cost if the damage was caused by a covered event (lightning, utility surge).
Don't Wait
Electrical fires in the United States cause over $1 billion in property damage annually. Many start inside the breaker panel — in the walls where you can't see them until it's too late.
If your panel smells like burning, call now. Not tomorrow.
