5 Hacks To Fix Your Broken Electrical Cord

An electrical cord has a lot of importance in the house. They extend the power outlets and increase the sockets. Most of the time, we never check them for damages until they get broken.

Your electrical cords get damaged over time because of exposure to weather elements, keeping heavy things on them such as the sofa, or sometimes they get eaten by an animal. You don’t have to buy a new one each time this happens.

In this article, we tell you five simple methods you can use to repair the cable yourself. Before you mend the extension, ensure to remove the plug from the electrical outlet.

1. Make Two Cords

If the electrical cord is very long, you can make two from it, such as a flat plug extension cord and a single plug extension cord. If it is not long enough, then you can only make one.

You can use this method to repair electrical cords with a broken power plug.

What You Need

Plug, receptacle, pair of pliers, or any tool that can cut the cord well.

What to Do

Using the pair of pliers, make a clean cut on both sides of the damaged section. You need to remove the areas with the damage.

On the cord with a receptacle, use the pliers or strippers to remove the insulation. Then expose about a quarter-inch of the wires and fix them into the plug. Ensure you correctly match wires with their terminals.

The ground wire goes into the ground terminal, the live wire into the live terminal, and the neutral into its terminal. On the other cord, fix the receptacle. Ensure you carefully match the cables to the terminals.

2. Use an Electrical Tape

What You Need

Electrical tape, pliers, and utility knife or razor blade

What You Will Do

Connection, Scissors, Tape, Cables, Wires, Electricity


Slit open the section with the damage to remove the broken part using the pair of pliers. Cut the insulator with the utility knife and carefully remove the colored wire wrap to expose the wire. Coil the wires that have a cover of the same color together. Using the electrical tape, cover the two sections separately until there is no wire visible.

You can then cover both wires together with the electrical tape until you completely cover the section without the insulation.

3. Heat Shrinking

What You Need

Heat shrink tubing, cotton wool and alcohol for cleaning, and a hot air gun.

What You Will Do

Get a heat shrink tubing of the correct size. It should be the same size as that of the cord. You can use a wrap-around tube.

Clean the area that you are repairing. Insert the cord into the tubing or wrap the tubing around it tightly. Using the hot air gun, heat the heat shrink tubing to shrink it until it tightly fits the cord. While you are heating, be careful not to overheat the section as this will make it melt or burn.

4. Use Crimping Butt Connectors

What You Need

Butt connectors of the correct size, wire cutter crimpers, electrical tape, and safety glasses.


Cut the extension into two at the point of damage using the crimpers. Using a pair of pliers or crimpers, remove the insulation from the wire carefully not to damage them. Extend the part without the insulation to about 10cm from the tip. Do this for both sides of the cord.

Cut the three electrical wires. Carefully remove about a quarter-inch of the colored rubber insulator around each wire. Ensure you don’t damage them.

Cables, Wires, The Combination Of, Connect

Insert wire on one side into the butt connector until all the exposed part is inside the butt. Press it using the crimpers so that it grips the wire. Repeat this with the other wire of the same color on the other cut end. Pull the two wires to see if the grip is tight. Do the same for the other wires.

Cover the wires by wrapping them together using electrical tape until you cover the section without the insulating material.

5. Soldering

What You Need

A soldering gun, a solder, and an electrical tape or shrink tube.

What You Will Do

Remove about one-half of the insulator from the wires. If you are using a shrink tube, insert the wire on one side into the shrink tube. Then cross the wires and twist them together. Using a soldering gun, heat the wire while holding the solder from the upper side.

Do this until the solder melts into the wires. Slide the solder along the wires until you cover the whole wire with the solder. Let the wire cool. Then bring the shrink tube and cover the soldered area. Use heat to shrink the tube. Alternatively, you can cover it using electrical tape.


You can save a lot of money by repairing broken electrical cords yourself instead of buying new ones. You can choose to use solder, an electrical tape, a butt connector, or shorten the cord to make two cords.

If the damage on the cords is extreme, or if you have repaired it several times, it will be wise to buy a new one. Using extremely damaged wires can be dangerous to you and your property.

When stripping, ensure you do not cut the wires. Cutting them increases their resistance, causing overheating, damaging the wires even more.
