Guide: How to Repair an Electrical Cord

Electrical cords break all the time. When you repeatedly use them to deliver power to a specific device or appliance, they’ll most likely develop a short or a stop at one time or the other. The good news however, is that you don’t have to keep buying new ones. It’s quite easy to repair them.

Knowing how to repair an electrical cord is quite useful because you won’t have to spend money repeatedly to fix them. If you’re not really a ‘handyman’ or aren’t skilled in any form of electrical work, don’t worry. The instructions below will help even absolute beginners to pull off this repair job.

Removing the Cord

While this might seem obvious, you want to make sure that no electricity is running through the cord when you’re removing it. Hence turn off the power before you remove the cord.

Performing a Visual Inspection

Once the cord is removed, do the following:

  • Inspect the ends of the cord – place your hand at the end and check for warmth, which could point to a problem. Pay attention to the prongs as well. Do they look blacked, twisted or burned?
  • Inspect the length of the cord – you want to check the cord for any signs of physical damage. This could be things like rips or signs of burns. You may want to run your fingers through the cord because sometimes it can be hard to see damaged areas. Once you spot any, make sure to mark them.

In most cases, you’ll be able to identify what the problem with a proper visual inspection. If the problem is not see apparent, we highly recommend that you contact the most capable electrician Galston has to offer.

Cutting the Cord

Once you’ve identified what the problem is then it’s time to cut the cord. Using a wire cutter, cleave as close to the damaged part of the cable as possible.

Replace the Cord Cap

Here are some tips to keep in mind when replacing the cord cap:

  • Use a cap with the same amount of prongs as the previous one. The amount of wires in the cable should point to that.
  • In the case of a cord with just two wires, you have to make sure to terminate each to the prong with the corresponding width in order to maintain the intended polarity.
  • Connect the blue wire to the neutral terminal.
  • Connect the green wire to the earth terminal.
  • Connect the black wire to the hot terminal.
  • Make sure that the wire strands are twisted together and wrapped in the clockwise direction around the appropriate terminal screw.
  • If there is a strain relief connector on the cap make sure not to tighten it too much. Otherwise this can end up damaging the wire insulation.


Plug in the cord to the outlet and to the device and appliance and turn the power on. Do not touch the cord just yet while the power is still running.

And that’s all there is to repairing an electrical cord. As you can see, it’s quite easy to pull off by yourself.
