Burning Smell from
Your Electrical Panel?

If you smell a burning odor coming from your electrical panel, treat it as a serious emergency and take immediate action. First, do not touch the panel if the smell is accompanied by heat or visible smoke — the panel enclosure itself could be energized. If it is safe to approach, turn off the main breaker to cut power to the entire home, then evacuate everyone from the house and call 911 if you see flames or heavy smoke. For less urgent situations where the smell is faint and there is no visible smoke or heat, call a licensed electrician immediately for an emergency inspection — we offer 24/7 dispatch and can usually arrive within an hour for urgent calls in Los Angeles. Do not reset any breakers or turn the panel back on until a licensed electrician has inspected it. The burning smell is almost always caused by arcing, overheating wires, or a failing component that can ignite surrounding materials.

A burning smell from your electrical panel is most commonly caused by one of several serious issues: a loose or corroded connection at the main breaker or bus bars that creates resistance and generates heat, an overloaded circuit where the breaker or wiring is running too hot, a failing breaker that is arcing internally, rodent damage where mice or rats have chewed through wire insulation creating short circuits, moisture intrusion inside the panel from a leaky roof or pipe above, or aluminum wiring connections that have deteriorated over time due to thermal expansion and contraction. Loose connections are the most common culprit we find when we investigate burning smells in Los Angeles homes — even a slightly loose screw terminal can generate enough heat to melt wire insulation and char the surrounding panel components. Each of these issues requires immediate professional diagnosis because they can rapidly escalate from a faint smell to an electrical fire.

Yes — a burning smell from your electrical panel is a serious fire risk that requires immediate attention. The odor you are smelling is likely melting wire insulation, which typically begins to decompose and release chemical odors at around 200 degrees Fahrenheit, long before visible flames appear. Electrical panel fires can start within minutes of the first burning smell if the underlying cause is arcing or a loose connection generating intense localized heat. The California Office of the State Fire Marshal reports that electrical distribution equipment — including panels, breakers, and wiring — is one of the leading causes of residential structure fires. Never ignore a burning smell hoping it will go away on its own. If the smell persists or returns after the panel has cooled down, there is an active problem that needs professional diagnosis. We provide 24/7 emergency service throughout Los Angeles for exactly this type of situation.
