What to Do When You Smell Burning Plastic Near Power Outlets

The Right Way to Responsd When Power Outlets Overheat

Noticing a burning-plastic smell near a power outlet is a clear indication that something isn’t right. That sharp, chemical odour often means an electrical component is overheating, whether it’s the outlet itself, the wiring inside the wall, or an appliance connected to it. Even a faint smell can be an early sign of a serious issue that needs attention before it becomes dangerous.

If the source of the smell is left unaddressed, it can lead to serious hazards such as electrical fires, damaged circuits, and even exposed live wiring inside the wall. The risk increases the longer the issue goes unchecked. In this guide, we’ll learn exactly what to do, what causes the smell, how to diagnose the risk, and when to call a licensed electrician for immediate assistance.

Step-by-Step: What to Do Immediately

1: Turn Off the Power at the Switchboard

The very first thing you should do is to cut the electricity to the affected area before you touch anything.

How to do this safely:

• Go to your electrical switchboard.
• Identify the circuit breaker labelled for the room or outlet.
• Switch it to the OFF position.
• If unsure, turn off the main switch to cut power to the whole property.

This instantly removes the heat source, preventing the situation from escalating.

2. Unplug Appliances (Only After Power Is Off)

Once you know the power is off, it’s safe to check the appliances connected to the outlet.

Take these steps:

• Unplug everything from the outlet.
• Move the appliances away from the wall.
• Inspect each plug for signs of melting, discolouration, or unusual heat.

Sometimes the smell isn’t coming from the outlet at all; it could be a faulty appliance that’s been overheating. But until you confirm the source, it’s best to treat the outlet and surrounding wiring as potentially unsafe.

3. Ventilate the Area

Open nearby windows and doors to allow fresh air to circulate through the space. Ventilating the area helps clear the initial odour and makes it easier to determine whether the smell was caused by a temporary issue or something more serious. It also reduces your exposure to potentially harmful fumes produced by melting plastic.

If the burning-plastic smell continues after ventilation, it’s a strong indication that the source is inside the outlet rather than an appliance. A persistent odour can signal ongoing hidden melting within the wall, which requires immediate attention from a licensed electrician.

4.  Inspect for Visible Damage

Carefully examine the outlet and the surrounding area for any signs that something has overheated.  Even small changes in appearance can reveal a serious underlying issue.

Check for:

• Darkened areas around the faceplate
• Plastic that looks warped, softened, or uneven
• Cracks or splits in the outlet cover
• Staining that wasn’t there before
• Any unusual texture, such as bubbling or rough patches
• Sounds coming from the outlet, like buzzing, crackling, or faint sizzling

These signs suggest the outlet has been under heat stress or has already begun to fail internally. Avoid using it until a licensed electrician has inspected the wiring and confirmed it’s safe.

What Causes a Burning Plastic Smell?

A burning-plastic smell around a power outlet usually points to overheating, but the underlying reasons can vary.  Identifying the source helps assess the risk and prevent further damage.

Common causes include:

• Overloaded circuits: Plugging too many high-demand devices into one outlet can generate excessive heat.
• Damaged wiring: Frayed or poorly connected wires create resistance, producing heat that can melt surrounding plastic.
• Faulty outlets: Old or defective outlets may fail internally, leading to overheating and burning smells.
• Overheating appliances: Malfunctioning appliances can overheat and melt their plugs, producing a strong odour.
• Poor-quality powerboards: Cheap extension cords often lack proper insulation and can overheat.

Every cause carries potential danger. If you’re unsure what’s causing the smell, it’s safest to call an Adelaide electrician immediately. At Aquila Electrical, our licensed electrician can quickly find the source and make sure your outlets and wiring are safe.
