An extension cord is used to power devices in areas with no electrical outlets. However, there are times when this cable is not long enough to reach where it is needed.
In this case, you may wonder can you plug an extension cord into an extension cord.
For this question, my answer is no. You can read below why doing so is not a good idea.

Can You Plug an Extension Cord Into Another Extension Cord?
Though connecting an extension cord into power strip can increase the range of your electrical connection, doing this is highly prohibited. This kind of setup can bring high risks of electrical hazards such as fire or electrocution.
When you daisy chain cables, you may encounter increased resistance, sudden power tter understanding of these problems, here is a brief explanation.
1. Increase in Resistance
Using a single piece of extension cord in one circuit will provide a good flow of electricity with normal resistance. However, the electrical flow will weaken when you connect two outdoor extension cords together, which can also result in higher resistance.
The result is an electrical surge that can damage devices connected to the extension cord. Furthermore, increasing the resistance may also result in overheating of wires.
Overheating of wire might also lead to sparking, which can start a fire or electrocution.
2. Sudden Power Loss
Using a long line of extension cords may also result in a sudden power loss due to voltage drop. It happens when electricity needs to travel a long way to run your devices.
When voltage drops occur, you may not be able to use your devices normally. For example, frequent turning off of your gadgets may happen, which can damage them.
Using the recommended extension cord rating for every electrical connection is best. Moreover, it is also a good idea to pick a larger wire gauge if you need to use a long cable.
3. Insulation Risk
The insulation or the wire cover is one of the most critical parts of the extension cords. It protects the wire inside and prevents electrocuting anyone around the cord.
When you combine cables, a circuit breaker will draw more power. As a result, wires may get heated, and their insulation undergoes wear and tear.
As a consequence, your damaged extension cord won’t be safe anymore. You will need to buy a new one, which can be costly and inconvenient.
- Pro tips: Instead of connecting two or more extension cords, you can install a new circuit and outlets in some parts of your house where you need to use electricity.
Furthermore, regularly checking your extension cords during and after use can provide additional safety. If you see some damage like burn marks or smells like burning plastics, I suggest not using your cable and immediately replacing it.
Other Things You Should Not Do With an Extension Cord
Aside from not connecting an extension cord to extension cord, there are other things you need to consider to have a safe working environment.
1. Do Not Overload Extension Cord
Extension cords have a rating based on their wire size, typically AWG. This rating tells us how much power it can hold without taking any damage.
- For example, a 16 AWG extension cord can only hold up to 10 amps of power. With it, you can only run a device with the same or a lower rating.
Trying to use this wire size with high-power devices may cause overheating of cords, which can result in fire or damage to your appliances.
- Similarly, a twin or double extension cord with a 13-amp rating won’t be able to handle a heater or AC.
If you need to use a high-power device, consider plugging it directly into your wall outlet or using larger AWG cords.
2. Do Not Allow Your Extension Cord To Become a Trip Hazard
In many houses, untidy or disorganized extension cords are frequently the source of accidents. You can get injured by accidentally stepping on them, and your little child and pets can play with these cables.
For this reason, it is best to place your extension cords away from high-traffic areas. This will prevent tripping hazards.
Furthermore, placing cables at the back of your sofa or other furniture may also keep your child and pets safe from electrocution.
3. Do Not Use Extension Cords as Permanent Outlets
Always remember that an extension cord is not rated for permanent use. In other words, you need to unplug and store it in a dry place to keep it in good shape and ready for the next use.
You can make the extension cord plugged into itself when coiling it for storage.
4. Do Not Cover Your Extension Cord
If you are using an extension cord inside and outside your house, it is a good idea to hide it. There are a lot of ways you can use to hide your cable for much safer and more secure electrical connections.
You can use furniture, a wire holder, or some DIY decoration to hide cords inside your house. At the same time, you can use plants, conduits, or a weatherproof box for concealing the connections outside your house.
However, always remember that it is not a good idea to conceal cables using rugs or carpets. The cords generate heat in usage, and covers can add to that, which may result in fire hazards.
Also, do not install your extension cord under the wall or ceiling as it requires better insulation to prevent overheating. Always keep the extension electrical socket and cord visible for quick detection of any problems.
Can you plug an extension cord into an extension cord?” People on forums like Reddit may give you different answers to such a question.
However, in terms of safety assurance and electrical standards, it is not allowable to have a daisy chain connection with an extension cord. Always remember that the most important thing is the safety of everyone inside and outside your house.
