he Biggest Mistake People Make With Extension Cords (And How to Stay Safe)
Extension cords and power strips are found in almost every home. They’re convenient for powering multiple devices, but using them incorrectly can create safety risks that many people don’t realize.
One of the most common mistakes is overloading an extension cord or power strip by plugging in several high-power appliances at the same time. Devices such as space heaters, air fryers, microwaves, coffee makers, and electric kettles can draw a large amount of electricity. When combined on the same extension cord, they may exceed its rated capacity.
Why Is This Dangerous?
When an extension cord carries more electricity than it’s designed for, it can overheat. Over time, excessive heat may damage the insulation around the wires, increasing the risk of melting, electrical failure, or even a fire.
Older or damaged extension cords can be especially risky because worn insulation or loose connections may generate additional heat.
Common Mistakes to Avoid
- Plugging multiple high-power appliances into one power strip.
- Connecting one extension cord to another (“daisy chaining”).
- Using indoor extension cords outside.
- Running cords under carpets or rugs where heat can build up.
- Using damaged or frayed cords.
- Ignoring warning signs such as a hot plug, burning smell, or discoloration.
