If you notice a burning smell from an outlet, a switch or the fuse box, it's not something that can wait until tomorrow. A smell of burning plastic or cable usually indicates active overheating, and it's one of the leading causes of house fires in Spain.
Unplug the appliance or isolate the affected area immediately and call an emergency electrician. At Servicio24 Electricistas we treat this type of call as a priority, 24 hours a day.
Most common causes of a burning smell
🔌 Worn-out outlet or socket
Loose or deteriorated contacts generate heat through resistance and eventually melt the plastic.
🧵 Overheated cable
A cable with insufficient gauge for the load it carries heats up and can eventually melt.
⚡ Circuit overload
Too many high-consumption appliances on the same circuit (heaters, air conditioners) generate excessive heat.
🔧 Loose connection in the fuse box
A poorly tightened terminal inside the fuse box creates an electrical arc and a burning smell.
🌀 Faulty appliance
Worn internal motors or heating elements can produce a burning smell even if the wiring itself has no fault.
🏚️ Overloaded old wiring
Wiring designed for lower consumption than today's (more appliances, more power) gets pushed beyond its original design.

Frequently asked questions about a burning smell
Is a burning smell from an outlet dangerous?
Yes, always. It indicates active overheating and is one of the most common causes of household electrical fires. Unplug the appliance and don't use it again until it has been checked.
Should I cut power to the whole house or just the affected circuit?
If you can identify the exact circuit, cutting that is enough. If you're unsure or the smell comes from the main fuse box, cut the main breaker for safety.
Can there be a fire risk even without visible smoke?
Yes. Overheating can produce a smell before any visible smoke appears. Don't wait for flames or smoke to act.
