Safely Use Extension Cords for Holiday Decorations

The holiday season is a time for festive lights and decorations, but improper use of extension cords can quickly turn your joy into a hazard. 

Every year, house fires are caused by overloaded circuits, damaged cords or incorrect setups – knowing how to safely use extension cords for holiday decor ensures you can celebrate the season while protecting your home and family. 

Here’s what you need to know to keep your holiday lights shining safely. 

Common Hazards When Using Extension Cords

Extension cords can be incredibly useful, but they also come with risks if not handled correctly. Here are some common dangers to watch out for: 

• Using cords that cannot support the wattage of your lights can cause overheating and spark fires. 
• Overloading circuits with too much power increases the risk of electrical fires or tripped breakers. 
• Damaging cords with nails or fasteners exposes the wires inside, leading to potential shocks or shorts. 
• Connecting too many cords together or to one power strip could melt the cords or start a fire. 
• Getting the cords or connections wet, as water and electricity do not mix. 

Key Tips for Extension Cord Safety

You can safely use extension cords for holiday decorations if you keep a few rules in mind:

1. Inspect Cords for Damage: Never use a cord with fraying, cracks or exposed wires. Damaged cords should be replaced immediately. 
2. Match Wattage Ratings: Make sure the cord’s wattage matches or exceeds the total wattage of the lights you’re plugging in. 
3. Use the Right Length: Choose cords that are only slightly longer than the distance needed. Excessively long cords can tangle or create tripping hazards, while cords that are too short may lead to unsafe conditions. 
4. Check Certification: Look for cords certified by independent safety organizations like UL (Underwriters Laboratories) to ensure quality and safety. 

Storing and Maintaining Your Extension Cords

Taking care of your extension cords is just as important as using them responsibly. When not in use, be sure to store them in a dry area, coiled up, to protect it from any damage. 

Plan to replace your extension cords every few years OR when any damage is found.

Choosing the Right Extension Cord for Outdoor Decorations 

Outdoor holiday decorations, such as large inflatables or string lights, often require higher power output than indoor decorations. To handle these demands safely, always use outdoor-rated extension cords, built with extra insulation to withstand moisture, temperature fluctuations, and exposure to the elements.

Options like the Southwire Outdoor 16/3 Vinyl Extension Cord are excellent for powering outdoor decorations. This cord is durable, weather-resistant, and can handle the wattage required for most outdoor holiday displays. 

Using indoor extension cords outside is not only unsafe but also increases the risk of electrical hazards. Always pair your outdoor decorations with the correct cords to keep your display both stunning and secure. 

Managing Multiple Extension Cords Safely

For larger holiday displays, you may need several cords to power everything. To stay safe, be sure to:

• Avoid Connecting Cords Together: Instead of chaining cords, use separate cords connected to different circuits to distribute the load.
• Know Your Circuit’s Limit: Check the circuit’s amperage to avoid overloading it. A 15-amp circuit supports 1,800 watts, while a 20-amp circuit can handle 2,400 watts. Calculate the total wattage of your decorations to make sure you’re staying within these limits. 
• Scale Back if Necessary: If your display exceeds the circuit’s capacity, reduce the number of lights or decorations, or consult an electrician about upgrading your panel for higher capacity.
