Tips from Your Electrician: How to Use Your Extension Cords Safely

There’s no question that extension cords offer a great deal of convenience. However, many people also recognize the risks of overloading them by plugging in too many devices. Doing so can overwhelm the outlet, potentially damaging connected equipment—or worse, causing an electrical fire. But overloading isn’t the only safety concern with extension cords. A qualified electrician would likely advise you to follow these additional safety guidelines:

Use the Right Cord for the Setting:

Most extension cords come with manufacturer instructions—be sure to read them carefully. One critical detail is whether the cord is rated for indoor or outdoor use. Using an indoor cord outside can be dangerous, as it isn’t built to withstand rain or harsh weather.

Match the Wattage:

The instructions will also indicate the cord’s wattage rating. Always ensure the cord’s rating matches the total wattage of the devices you intend to plug in. This precaution helps prevent overheating, which could otherwise lead to a fire.

Don’t Cover Extension Cords:

While extension cords might detract from your décor, covering them with rugs or other materials is unsafe. Trapped heat can build up beneath the covering, potentially igniting it. When you’re finished using an extension cord, it’s best to unplug it and store it away.

Never Use Damaged Cords:

Over time, extension cords can develop wear and tear. If you notice any damage, it’s safest to replace the cord. Damage could compromise critical safety features, and cords with exposed wires pose serious risks of shock or electrocution.
