Why Using an Extra-Long, Coiled Extension Cord Is a Safety Hazard

Extension cords are incredibly convenient—but they’re often misunderstood and misused. One of the most common (and dangerous) mistakes we see is using an extension cord that’s far longer than necessary and leaving the extra length coiled or bunched up.

At Kennedy Electric, we want homeowners to understand why this is a problem and how to use extension cords safely.

🔥 Heat Buildup Is the Biggest Risk

When electricity flows through a cord, it naturally generates heat. When a cord is fully extended, that heat can dissipate into the air. But when excess cord is coiled, looped, or piled up, the heat gets trapped.

This trapped heat can:

• Break down the cord’s insulation

• Cause the cord to overheat

• Increase the risk of electrical fires

• Damage the appliance or tool being used

The higher the electrical load (power tools, heaters, compressors), the greater the danger.

⚡ Longer Cord ≠ Better Cord

Using a cord that’s much longer than needed also creates voltage drop, meaning your equipment may not receive the power it needs. This can cause motors and tools to:

• Run inefficiently

• Overheat internally

• Wear out faster

In some cases, this added strain can trip breakers or damage sensitive electronics.

✅ Best Practices for Extension Cord Safety

To reduce risk:

• Always use the shortest extension cord possible

• Fully uncoil cords before plugging them in

• Match the cord’s gauge and rating to the appliance or tool

• Never run cords under rugs, through doorways, or near heat sources

• Avoid using extension cords as a permanent solution

If you’re constantly relying on extension cords, that’s often a sign you need additional outlets or circuit upgrades.

🛠 When to Call a Professional

Extension cords are meant for temporary use only. If your home, garage, or workshop doesn’t have power where you need it, Kennedy Electric can help with:

• Installing new outlets

• Adding dedicated circuits

• Upgrading existing electrical systems

• Improving overall safety and code compliance

⚡ Final Thought

A messy extension cord may seem harmless—but when it’s too long and left coiled, it can quickly become a serious hazard. A little awareness goes a long way toward protecting your home and family.
