When working outdoors, always use extension cords rated for exterior use. These cords feature more durable insulation and weather-resistant materials to protect against moisture, UV rays, and extreme temperatures. Neglecting to use an outdoor-rated cord can result in rapid deterioration, increasing the risk of electrical shock and fire.
2. Overloading Extension Cords
Another common mistake is overloading extension cords by plugging in too many devices or exceeding the cord’s amperage capacity. Each extension cord has a specific amperage rating, which determines the maximum amount of electrical current it can safely carry. When you overload a cord, it can overheat, melt the insulation, and potentially start a fire.
To prevent overloading, familiarize yourself with the amperage requirements of your devices and the capacity of your extension cords. Avoid plugging multiple high-powered appliances into a single cord, and never daisy-chain multiple extension cords together. If you find yourself consistently overloading extension cords, it’s a clear sign that you need to install additional outlets in your home or workplace.
When in doubt, use a power strip with built-in circuit protection. These devices feature a circuit breaker that trips when the connected load exceeds a safe level, preventing overheating and potential fires. However, remember that power strips are not a substitute for proper electrical wiring and should only be used as a temporary solution.
If you’re unsure about the amperage requirements of your devices or the capacity of your extension cords, consult a licensed electrician. They can assess your electrical needs and recommend the appropriate cords and outlets to keep your home or workplace safe and functional.
3. Running Extension Cords Through Doors, Windows, or Walls

When a cord is compressed or pinched, it can damage the insulation and expose the wires, increasing the risk of electrical shock and fire. Additionally, cords that are run through walls or ceilings can overheat due to lack of airflow, leading to a potential fire hazard.
To avoid these risks, always use extension cords as intended – out in the open and away from foot traffic. If you need to run a cord through a doorway, use a cord cover or protector to prevent damage from the door’s edges. These devices, like the D-Line Cable Protector, feature a low-profile design that allows doors to close safely while protecting the cord from pinching and abrasion.
If you find yourself frequently running extension cords through windows or walls, it’s time to consider installing additional electrical outlets. While this may require a more significant investment upfront, it’s a far safer and more convenient solution in the long run. A licensed electrician can assess your power needs and install outlets in strategic locations to minimize your reliance on extension cords.
Remember, extension cords are designed for temporary use only. If you need a permanent power solution, it’s always best to invest in proper electrical wiring that meets local building codes and safety standards. By doing so, you’ll not only reduce the risk of electrical hazards but also improve the functionality and value of your property.
4. Neglecting to Inspect and Maintain Extension Cords
Extension cords are subject to wear and tear, especially when used frequently or in harsh environments. Over time, the insulation can crack, fray, or degrade, exposing the wires and increasing the risk of electrical shock and fire. Additionally, bent or kinked cords can damage the internal wiring, leading to overheating and potential hazards.
To keep your extension cords in top condition, inspect them regularly for signs of damage. Look for frayed or cracked insulation, exposed wires, loose connections, and bent or missing prongs. If you find any of these issues, replace the cord immediately. Don’t attempt to repair damaged cords with electrical tape or other makeshift solutions, as this can create an even greater safety risk.
When storing extension cords, avoid wrapping them tightly around objects or leaving them in tangled heaps. This can cause kinking and damage the internal wiring. Instead, use a cord reel or organizer to keep your cords neat and protected. The Bayco Cord Storage Reel is a great option for safely storing and transporting extension cords, preventing damage and extending their lifespan.
In addition to proper storage, protect your extension cords from moisture, extreme temperatures, and direct sunlight. These environmental factors can degrade the insulation and compromise the cord’s integrity. When using extension cords outdoors, opt for weather-resistant models and keep them clear of standing water and snow.
5. Using Extension Cords as a Permanent Power Solution
One of the most dangerous mistakes people make with extension cords is using them as a permanent power solution. Extension cords are designed for temporary use only and should never be used as a substitute for proper electrical wiring. When used long-term, extension cords can overheat, deteriorate, and create serious fire hazards.
If you find yourself consistently relying on extension cords to power your devices, it’s a clear sign that you need to upgrade your electrical system. A heavy reliance on extension cords indicates that you have too few outlets to meet your power needs. In this case, the safest and most effective solution is to have additional outlets installed by a licensed electrician.
Not only will proper electrical wiring reduce your risk of fire and electrical shock, but it will also improve the functionality and convenience of your space. With strategically placed outlets, you’ll be able to power your devices without the clutter and hazards associated with extension cords. Plus, a well-designed electrical system can increase the value of your property and ensure that your home or workplace meets local building codes and safety standards.
If you’re renting a property and find that the existing outlets are insufficient for your needs, talk to your landlord about potential solutions.

By addressing the issue proactively, you can prevent the temptation to rely on extension cords as a long-term power solution.
6. Ignoring Proper Grounding and Polarization
Extension cords come in various configurations, including two-prong and three-prong designs. The third prong on a three-prong plug is a grounding wire, which provides a safe path for electrical current to follow in the event of a short circuit or other malfunction. This grounding wire is crucial for preventing electrical shock and fire hazards.
A common mistake people make is using three-prong plugs with outlets that only have two slots. Never cut off the ground pin to force a fit, as this removes the critical safety feature and increases the risk of electrical shock. If you have older outlets that don’t accommodate three-prong plugs, have them replaced by a licensed electrician to ensure proper grounding.
Similarly, some extension cords feature polarized plugs, where one blade is slightly wider than the other. This design ensures that the cord is inserted into the outlet correctly, maintaining the proper polarity and reducing the risk of electrical shock. Always match the plug configuration to the outlet and never force a fit or modify the plug.
When purchasing extension cords, look for models that have been approved by independent testing laboratories like UL, ETL, or CSA.
