how to safely run an extension cord under a rug

Running extension cords under carpets or rugs to conceal them can create a tripping hazard. Furthermore, it can cause the cord to generate more heat or become damaged without you realizing.

However, this trick also helps prevent tangled cables, which can be inconvenient to unravel.

If you’re determined to hide cords under carpets despite the risks involved, read the guide below. It will show you how to safely run an extension cord under a rug, or at least, minimize potential hazards while doing so.

Ways to Safely Run an Extension Cord Under a Rug


An extension cord might not be the best way to energize your electronic devices. However, it is certainly convenient if your room does not have enough outlets.

Unfortunately, the risk of extension cord under rug fire hazard is high. Even if you just tape it onto the floor, the cable will pose the same problem.

Even though this is not recommended, you will still see a lot of suggestions and guides for this kind of trick on forums like Reddit.

So, if you still want to run a cord under carpet, there is a proper way to do it, and here’s how.

What To Prepare

  • Tape measure for measuring the path for the extension cord
  • Heavy-duty thin extension cord
  • Floor cord cover for additional protection of the cord
  • Scissors for cutting the floor cover
  • Clean cloth or rug for cleaning the path

Step 1. Plan a Route


Before you start, you need to plan a route for your extension cord from the nearest outlet up to where you need to power your devices. Though you might need a longer cord, it is a good idea to route it to the edge of the room to reduce the risk of tripping.

Then, use the tape measure to measure the route and see which cable length is suitable for your application.

Also, ensure the floor cord cover is equally long, so it can hide the extension. Cut the cover if necessary.

Step 2. Clear the Path

For you to install the extension cord properly based on your preferred route, you should clear the path first.

Remove all unnecessary things, such as furniture or appliances that your cord may pass through. Moreover, temporarily lift the rug to make way for the installation of the floor cover, together with your extension cord.

Once all is clear, you can now start positioning the extension cord properly.

Step 3. Place the Extension Cord


Clean the floor surface using a clean cloth or rag.

Then, to place a flat power cord under rug, put its plug next to the outlet’s location, but don’t insert it into the socket yet. Next, place the cord alongside the wall base on your route.

Once done, you can insert the cord into the under carpet cable protector. Apply the cord cover adhesive to the floor, and stick it into place.

Step 4. Bring Back The Rug and Other Furniture

Now, you can bring back mats to cover electrical cords, plus all the furniture and appliances.

Also, plug in the extension cord at the outlet and connect some devices to see if the cable will get too hot.

Note: In this guide, we suggest using a flat extension cord for under rug application. One advantage of picking such an under door extension cord is preventing bulges on the rug, making your work look even better.

In addition, using a Clear max 3-in-1 extension cord might be a good choice, as you can power multiple devices at the same time.
