There is a burning smell coming from an outlet

Is this an emergency?

Yes — treat it as one. Overheating at outlets, switches and their connections is a well-documented cause of home electrical fires, and the smell of hot or burning plastic is the warning that arrives before visible damage.

Call 911 immediately if there is smoke, any flame, scorching or melting visible on the faceplate, or a crackling or sizzling sound. Do not open the device, do not throw water at it, and get people out of the area first. Everything else on this page applies only after there is no active fire risk.

What should I do right now?

1. If there is smoke, flame or scorching: evacuate and call 911 before anything else.
2. If not: unplug anything from that outlet only if the plug and cord are cool to the touch and undamaged.
3. Switch off the breaker that feeds that circuit. If you cannot identify it, switch off the main breaker.
4. Keep the circuit off. Do not reset it 'just to see' — reenergizing an overheating connection is how a smell becomes a fire.
5. Note what was plugged in and how long it had been running. Space heaters, portable AC units, air fryers and window units draw enough current to expose a marginal connection.

What might cause this?

• A loose connection at the outlet's terminal screws or a back-stabbed push-in connection, arcing and heating under load
• An outlet or receptacle at the end of its service life, with worn contacts that no longer grip a plug firmly
• A high-draw appliance on a circuit or extension cord not rated for it
• Aluminium branch wiring terminated on devices not listed for aluminium conductors
• Water intrusion into an exterior or bathroom outlet
• A damaged plug or cord overheating at the point of contact rather than the outlet itself

Who should I call?

A licensed electrician, and specifically one who will open the device and inspect the terminations rather than just swap the faceplate. The fault is usually at the connection behind the outlet, and the same fault may exist at other devices on that circuit if the wiring method or the original workmanship is the cause.

If there was any fire, the fire department attends first and an electrician follows. If the smell is accompanied by scorching at the panel rather than the outlet, say so when you request help — panel work is a different scope and often a higher priority.

When another trade may also be needed

If water is what got into the outlet — a roof leak above a wall, a plumbing leak in the cavity, or storm intrusion — the electrical repair is only half of it. Finding and stopping the water is a plumbing, roofing or water-damage job, and the wall cavity has to be dry before the circuit is put back into service.

What not to do

• Do not reset the breaker to test whether the smell returns.
• Do not simply replace the faceplate or plug something else in to check.
• Do not use water or a standard extinguisher on an energized electrical fire; if the fire department is coming, let them handle it.
• Do not keep using extension cords or power strips as a workaround for that circuit.
