How To Fix A Chewed Wire: How To Repair A Chewed Power Cord?

Do you want to know how to fix a chewed wire? A chewed cord doesn’t require professional help to fix. Follow these steps. The double shock of finding the power cable of a light or appliance chewed through by the household pet is real. If your cord has been chewed on, here are two quick repairs.

Pets in the home may result in damaged electrical cords that need to be fixed. Many families deal with this issue regularly.

You can easily fix a cable that has been chewed on. It is safer to carefully insulate the repair and solder any electrical connections to prevent fires. With this method, your broken cables will function as well as new in no time.

The topic of today’s piece may seem unrelated, but you have no idea how often it’s come up for us. We have had to replace a number of plugs, including those for extension cables and power equipment.

The extension cord on a friend’s crock pot melted, the dog chewed through the cable to a light, a neighbour burnt the cord on our sander, and so on and so forth.

In light of the high cost of extension cables and power equipment, this is a fantastic method to cut costs. And you’ll be done in no time! I wouldn’t recommend taking on a home repair project without the proper preparation, but if you’ve ever installed a light fixture, you’ll find this one a breeze.

While it is possible to just replace the cord and splice it back together, I believe this procedure to be simpler and more reliable in the long run. In this way, broken cables and faulty plugs may be easily replaced.

9 Ways To Protect And Fix Cords Around The Home

How often do you find yourself replacing wires around your house because of fraying, animals, or accidents? There are several low-cost alternatives to replacing cables that will keep yours looking like new for much longer.

This advice is applicable to the vast majority of household cables.

However, the repair tools are only safe for use on low-voltage cables, such as those used for charging mobile devices, gaming controllers, and headphones.

If a bigger cord, such as an extension cable, becomes broken, it should be thrown away immediately to reduce the risk of electric shock or fire. Before attempting any of these methods, make sure you unplug everything.

Tubed armored cords

Is your pet a cable chewer? There’s a simple method to keep curious toddlers from nibbling on them. To protect exposed wires, you may purchase a roll of transparent vinyl tubing, cut a slit in it, and slide it over the cables. (Byronicg, your helpful suggestion is appreciated.)

Spiral-wrap the cables.

Spiral wrap is another option to sheathe your cables if the idea of cutting tubing seems too laborious. Spiral wrapping is wonderful since it permits the use of numerous cables at once.

Protect wires by wrapping them with heat-shrink tubing.

Shrink tubing can be used to repair a cable whose outer sheath has become disconnected. Carefully sever two 1.25-inch-long segments of shrink wrap tubing. The ends of the cord should be coated with a thin layer of silicon adhesive.

Slip the tubing onto the cord so it covers the ends where the cord meets the connectors before the silicon dries. Remove any extra silicone and heat-shrinking the tubing over a lighter to reduce its size.

Don’t get too near to the flame with the lighter. If the cord becomes too hot, it might melt. If the thought of using a lighter to shrink the tubing gives you the willies, you may always resort to the safest alternative: turning on the blow dryer to its maximum heat setting.

To avoid fraying, use pens.

Phone charging cables and headphone jacks are two examples of cords that are more prone to fraying. A frayed end may be avoided with an ink pen.

You may get rid of the spring by disassembling a clicking ink pen. Extend the spring’s length, and then coil it around the cord’s foot. The wire provides the perfect amount of reinforcement to avoid fraying.

Patching up the cables using plastic welds.

After the harm has been done, cables can be repaired by welding them back together. If you have a broken cable, all you need is a minute with Bondic, the plastic welder.

Simply wipe down the cord, apply Bondic to the damaged area, then cure the plastic using the LED light provided in the repair kit.

Electrical tape can be used.

Wrapping the frayed cord in electrical tape is a quick and inexpensive remedy. First secure the frayed end, and then work your way outward along the cord a couple times.

Create a fresh cable by painting it

You may fix frayed or damaged wires with liquid electrical tape, such PlastiDip or Gardner Bender. Just put on two coats and wait for them to dry.

Toy solution to cord issues

Did you know that the hands of Lego figures are just the right size for gripping cables? Put a Lego figure on the wall near your outlet to remind you to bring the wires with you. To prevent your pet from chewing on unused cables, place them in his Lego hands.

Avoid stepping on them.

It’s been over a century since I moved into my house, and because of its age, there aren’t many plugs. Therefore, cords are stretched across the areas where people walk, which is a terrific technique to swiftly degrade cables.

Protecting cables with a cable bridge, such as this two-channel protector or the Vestil rubber cable protector, is an excellent solution.

  • Scissors or wire cutters
  • Strippers with razor blades and a built-in wire cutter.
  • Plug Replacement – A commercial quality plug like this is what you want for outside plugs like power tools, extension cables, etc. Inexpensive plugs can sometimes be pulled out of wires over time. Switch out a two-prong plug for another two-prong plug, and a three-prong plug for another three-prong plug.

The wire gauge, or AWG, is indicated by the numbers on the side of stripper tools. The AWG number increases as the wire diameter decreases. Most wire strippers will feature two sets of numbers, one for stranded and one for solid wire, so be aware of the difference.


A high-quality pair of strippers is your best chance for dealing with thin-walled or tiny wires. Here is a basic primer on how to use strippers if you’ve never done so before.

I prefer extremely sharp cutting pliers when I need to sever or peel thick plastic insulation from large or numerous wires. Even if you have the proper size, traditional wire strippers have a hard time removing the plastic coating. Pliers for cutting wires don’t need to be particularly big or heavy; you just need to make sure they’re sharp and be prepared to rotate them as you work.

The blades of certain strippers may be removed to reveal flat pliers. If you discover a decent pair that works for you, I have nothing against them. However, I don’t like many of them because they tend to crush more than truly cut.


Tips for recognising wires and terminals are provided here, but the detailed instructions for a three-prong plug may be found at the bottom of this page alongside accompanying photographs.

  1. Cut the wire directly behind the broken section with wire snips or scissors. It’s important to make sure the device is disconnected.
  2. Remove the protective covering by carefully cutting away 1″ of it, being careful not to cut into the wires. The quickest method is to cut off the top and bottom inches with a razor blade, followed by the removal of the packaging. You need around an inch of skin to show.
  3. Locate the cables. If your plug has three prongs, the white wire is always the neutral. Green or bare copper indicates the ground line. The black wire at the very end is the live one.
  4. Remove the insulation and the colourful sheathing from the wire by slicing off half an inch using wire strippers (or a razor). If you accidentally sever or cut into the wire, you may just trim the casing and try again.
  5. Remove the old plug and insert the new one as directed. Coupling the silver pinch point with the white (neutral) wire. Secure the wire by tightening the screws. The black wire (which is hot) is inserted into a pinch point that is bronze or copper coloured. The ground, represented by the green wire, must be inserted into the corresponding green pinch point. Additionally, be sure to tightly screw in all cables.
  6. Reinsert the replacement plug’s cover, taking care that no wires or housings protrude from the plug’s inside. Make sure that when you pull on the plug, the wires do not come loose from the casing.

A helpful hint is to wrap the wires in tape and name them so they don’t become jumbled up again after you’ve figured out which ones they are. (This helps me move things forward faster on occasion.)


The procedure is similar to that of the standard three-prong plug. However, a two-prong cable does not have a grounded or green wire.

  1. Cut the wire directly behind the broken section with wire snips or scissors. Make sure the plug is removed from the device.
  2. Unwrap the cables. If your two-prong appliance cable has a protective sheath, which is unusual, cut it off about an inch before the end. The two layers may need to be peeled apart. Expose the metal by slicing off half an inch of the plastic sheathing that surrounds the wire.
  3. Remove the old plug and insert the new one as directed. The screw terminals should be silver on one side and bronze or copper on the other. Coupling the silver pinch point with the white (neutral) wire. Tighten the screw to secure the wire. The black wire (hot) is put into the gold pinch point.
  4. Reinsert the replacement plug’s cover, taking care that no wires or housings protrude from the plug’s inside.
  5. Make sure that when you pull on the plug, the wires do not come loose from the casing.
  6. Putting a neutral wire into a silver terminal’s crimping point, in close-up.

To tell which wire is which, look for the neutral (white) wire to be identified by writing along its length, ribs, a white stripe, or a very light white coating. The neutral wire can be located by the prongs if you can’t tell by looking at the cord. To prevent accidental plugging in, most newer appliances feature two distinctly sized prongs on their power cables. The bigger prong on these wires always goes to the neutral.

How To Fix A Chewed Wire In 7 Steps

Assess and Strategize

  • Replacement of the entire cable is necessary if it is old, fragile, and splits easily. The appliance may need to be disassembled. Do not attempt to do so without first consulting an expert. A damaged or frayed power cable should be replaced if its bare wires can be seen.
  • To fix an electrical cable that was chewed up by a pet, just remove the plug, cut the cord, and plug it back in.
  • Your pet chewed through the cord? Remove the damaged portion and splice the remaining ends together.
  • Replace the cord if it has been chewed near the appliance.

Polarized Plug and Cord

You may tell which of your cord’s wires is the neutral by looking for a white stripe or inscription on one of them; some neutral wires are also ribbed.
A plug’s neutral terminal is the biggest prong.

Strip, separate, and cut the wires.

  • Use a wire cutter to snip out the chewed piece of the cord, then plug it back in.
  • Pull the wires apart until you have freed up a space of around two inches.
  • Use a wire stripper to cut out a quarter of an inch from each ends of the two wires.
  • To prevent the wires from fraying, twist the ends together.
  • Wrap each wire around the handle of a screwdriver to create a loop.

Join the Two Ends of the Cable

  • In order to gain access to the prong terminals, you will need to remove the cover from the new plug. Every plug is different, so you may need to unscrew it or take off the cover to access the internals.
  • First, loosen the screw on the big prong of the plug, then loop the neutral wire around the screw and tighten it.
  • The second prong must be treated in the same manner.
  • Install the screw and plug cover.

Separating the Strands

  • Use a wire cutter to remove the chewed piece of the cable.
  • Wrap some 4-inch Heat Shrink Tube around a wire.
  • It’s recommended to cut the cables at a depth of two inches.
  • Use a wire stripper to cut out roughly an inch from each of the four wires.

Connectors for wires that are soldered together and sealed

  • One of the wires has to have a Solder Seal Wire Connector slipped over it.
  • Get the two wires to twist together. (Twist together just two wires of the same colour.)
  • Reposition the plug such that the centre of the solder ring meets the splice’s centre.

Warm Up That Soldering Iron

Start by melting the central solder ring using a heat gun, then shrink the outside two rings. In order to heat the connection uniformly, you should rotate it.
For the other wire, just repeat the procedure outlined in the previous sentence.
