How to Safely Use Extension Cords Outdoors This Summer

As the warm weather settles in and outdoor activities become a regular part of our daily lives, extension cords are a go-to solution for powering everything from garden tools to outdoor lights and music systems. However, while extension cords are convenient, using them improperly—especially outdoors—can lead to dangerous situations like electrical shocks, fires, and equipment damage. At Sparks Electrical Contracting, we believe that safety should always come first. In this blog, we’ll walk you through the best practices for using extension cords outdoors this summer.

1. Choose the Right Extension Cord for the Job

Not all extension cords are created equal. For outdoor use, it’s essential to pick the right type of cord. Look for cords that are specifically labeled for outdoor use—these are designed to withstand the elements and ensure safety. Outdoor extension cords are typically thicker, more durable, and feature a weather-resistant outer coating.

Key Tip: Ensure the cord is rated for the wattage or amperage of the equipment you're powering. For example, if you're using a heavy-duty power tool, make sure the extension cord can handle the load. The cord's packaging will usually include information on how much power it can safely support.

2. Inspect the Extension Cord Before Use

Before plugging in your extension cord, always inspect it for any signs of wear or damage. Look for frayed wires, exposed copper, cuts in the insulation, or kinks in the cord. If you notice any damage, replace the cord immediately. A damaged extension cord can pose a serious safety risk, especially when used outdoors where moisture and weather can increase the danger.

Key Tip: Check the prongs of the cord as well. If they’re bent or missing, it's time to toss the cord and get a new one.

3. Avoid Overloading the Extension Cord

Overloading an extension cord is one of the most common causes of electrical fires. Always be mindful of how many devices you are plugging into the cord, and make sure the total wattage or amperage does not exceed the rating on the extension cord. This is especially important when using high-powered outdoor equipment like lawnmowers, outdoor heaters, or power tools.

Key Tip: Instead of daisy-chaining multiple cords together, use a cord that’s long enough to reach your power source. This reduces the risk of overloading and keeps your setup safer.

4. Use Properly Rated Outdoor Outlets

Make sure that the electrical outlets you’re plugging your extension cord into are properly rated for outdoor use. Outdoor outlets should be weatherproof and equipped with Ground Fault Circuit Interrupter (GFCI) protection, which helps protect against electric shock in wet conditions.

Key Tip: If your outdoor outlets aren’t GFCI-protected, consider having Sparks Electrical Contracting install GFCI outlets to enhance safety. These outlets are especially important for areas exposed to rain or moisture.

5. Keep Extension Cords Dry and Elevated

Water and electricity do not mix. One of the biggest risks when using extension cords outdoors is exposure to rain or moisture, which can cause electrical shocks or short circuits. Whenever possible, keep your extension cord elevated and away from puddles, wet grass, or standing water.

Key Tip: Use a waterproof cover or cord protector to prevent water from getting into the plug connections. If the cord must be on the ground, make sure it’s placed in a dry area and that the plug is elevated to avoid moisture damage.

6. Don’t Use Extension Cords for Permanent Outdoor Wiring

Extension cords are designed for temporary use, not as permanent wiring solutions. While it may be tempting to leave an extension cord out for the entire summer, it's important to remember that these cords are not meant to withstand prolonged exposure to the elements over time. If you find yourself needing a permanent solution for outdoor power, consider having a dedicated outdoor outlet installed by a professional electrician.

Key Tip: For long-term outdoor power needs, hire Sparks Electrical Contracting to install outdoor outlets or hardwired connections that are safe, weatherproof, and code-compliant.

7. Avoid Tripping Hazards

When using extension cords outdoors, always make sure they’re laid out in a way that doesn’t create a tripping hazard. Cords should be placed along walls, fences, or edges of pathways where they are less likely to be in the way. If the cord needs to cross a walkway, make sure it’s properly secured with cord covers or tape.

Key Tip: If you're using the cord for a party or gathering, consider using a cord protector or cable ramp to keep the cord elevated and out of the way.

8. Store Extension Cords Properly When Not in Use

When the summer season winds down, or when you're not using your extension cord, be sure to store it properly. Never leave extension cords coiled up tightly, as this can cause damage to the internal wiring. Store your cords in a dry, cool place to avoid exposure to moisture, heat, or UV rays, which can deteriorate the cord over time.

Key Tip: Coil your extension cord loosely and store it in a designated area, such as a garage or shed, to ensure it stays in good condition for next summer.

9. Disconnect Cords Properly

When you're done using your outdoor extension cord, always disconnect it by pulling on the plug, not the cord itself. Tugging on the cord can cause internal damage to the wiring and create a potential safety hazard the next time it’s used.

Key Tip: After disconnecting, ensure that the cord is dry and clean before storing it to prevent the buildup of dirt or moisture inside the plugs.

Conclusion

Using extension cords outdoors is convenient, but it’s crucial to follow safety precautions to avoid accidents and ensure everything runs smoothly. By choosing the right cord, inspecting it regularly, and following the tips above, you can enjoy your outdoor activities with peace of mind this summer.
