Assess the damage
Before attempting any repairs on an electrical cord, it is important to assess the damage and determine the extent of the issue. Here are some steps to follow when evaluating a chewed electrical cord:
- Safety First: Start by ensuring your safety. Shut off the fuse or circuit breaker to cut the power supply to the electrical cord. This is crucial to prevent any accidental electric shocks during the assessment process.
- Visual Inspection: Begin by carefully examining the cord. Look for any signs of damage, such as exposed wires, broken insulation, or frayed sections. Pay close attention to the severity of the chewing and identify the exact location of the damage.
- Feel for Warmth: Run your fingers along the entire length of the cord to detect any unusual warmth. A warm cord could indicate an internal issue, such as a damaged wire or a potential short circuit.
- Inspect the Plug: Check the plug prongs for any signs of melting or burning. If the chewing occurred near the plug, you may need to replace the entire plug or re-attach the plug assembly.
- Identify Wire Damage: If there are exposed wires, carefully inspect them for any breaks or fraying. Identify the type of wire by looking for markings or colour-coding. For example, a white stripe or writing often indicates a neutral wire, while the hot wire usually has smooth insulation.
- Assess Cord Condition: Consider the overall condition of the cord. If it is old, brittle, or easily cracks, it may be wiser to replace the entire cord rather than attempting a repair.
- Mark Damaged Areas: Once you've identified all the damaged areas, mark them for easy reference. This will help you during the repair process or when seeking professional assistance.
Remember, if you see extensive damage, exposed wires, or feel unsure about your ability to repair the cord safely, it is best to seek professional help or purchase a replacement cord to ensure your safety.

Cut out the chewed section
If your pet has chewed through an electrical cord, it is important to act quickly to prevent any potential safety hazards. Here is a step-by-step guide to repairing the chewed section:
- Assess the Damage: Before beginning any repairs, it is crucial to inspect the cord thoroughly. Shut off the fuse or circuit breaker to ensure safety during the repair process. Feel the entire length of the cord to check for unusual warmth, which could indicate internal damage. Look for breaks in the insulation and exposed wires, as these will require immediate attention.
- Cut the Cord: Using a wire cutter, carefully cut out the damaged or chewed section of the cord. Ensure you cut above and below the affected area to completely remove it. Be cautious not to cut any intact wires accidentally.
- Separate the Wires: Once you have two separate sections of the cord, gently pull the wires apart to create a small gap, approximately one to two inches, between the cut ends. This step is crucial for reconnecting the wires securely.
- Strip the Wire Ends: Using a wire stripper, carefully strip off about one inch of insulation from the ends of each wire. This step will expose the conductive metal, allowing for secure connections. Take care not to damage the wires during this process.
- Twist the Wires: Twist the ends of each wire together securely. Ensure that the connections are tight and no longer frayed. This step helps create a solid and reliable connection between the two sections of the cord.
- Create Wire Loops: Take each twisted wire and carefully wrap it around a screwdriver to create a small loop. This step will help with the alignment and connection inside the replacement plug. Ensure that the loops are tight and secure.
By following these steps, you can effectively remove the chewed section of the electrical cord and prepare the wires for the next stage of the repair process. Remember to work carefully and always prioritize safety when dealing with electrical repairs.

Splice the wires
Before you begin splicing the wires, make sure to shut off the electricity. Turn off the fuse or circuit breaker, which is usually located in a basement or storage room. Inspect the cord for any signs of damage, such as broken wires, unusual warmth, or breaks in the insulation. If there is severe damage, it may be best to purchase a new cord.
Now, cut the chewed section out of the cord using a wire cutter. Separate the wires by pulling them apart about one to two inches down. Strip about one inch off the ends of the wires using a wire stripper. Twist the ends of the wires tightly so they are no longer frayed. Make a loop on each wire by wrapping it around a screwdriver.
Next, slip a Solder Seal Wire Connector over one of the wires. Twist the two matching wires together, ensuring that you connect neutral to neutral and hot to hot. Move the connector so that the middle solder ring aligns with the middle of the splice.
Using a heat gun, heat the middle solder ring until it melts, and then do the same for the other rings. Rotate the connector to ensure even heat application. Repeat this process for the other wire. Once both wires are connected, slip a heat shrink tube over the connectors and apply heat until it shrinks, rotating the cord for even heat distribution. Alternatively, use electrical tape to cover the connectors.

Use electrical tape
Before attempting to repair a chewed electrical cord, it is important to assess the extent of the damage. If the cord is old, brittle, or has bare wires exposed, it is best to replace the entire cord or plug. However, if the damage is limited to a small section of the cord, it can be repaired by cutting out the affected area and splicing the remaining portions together. This can be achieved using electrical tape, which is designed for use on electrical components and provides insulation and protection.
To begin the repair process, use a wire cutter or a pair of end-cutting pliers to remove the damaged section of the cord. Ensure that you cut on both sides of the damaged area to completely isolate it. The length of the remaining cord should be sufficient for splicing, so consider this before cutting. Once the damaged section has been removed, separate the wires by pulling them apart carefully.
The next step is to strip about one inch of insulation from the ends of the wires using a wire stripper or a utility knife. Be careful not to damage the wires during this process. After stripping, twist the ends of the wires together tightly to ensure a secure connection. Form a loop with each wire by wrapping it around a screwdriver or a similar tool. This will create a neat connection point.
Finally, it is time to apply the electrical tape. Electrical tape is a type of black vinyl that resists electricity and provides insulation. Take the edge of the tape and place it over the spliced wires, ensuring that it covers the broken casing. Wrap the tape tightly around the repaired area several times, creating a well-sealed barrier. Electrical tape is ideal for insulating wires and preventing further superficial damage. However, if there are exposed metal wires, additional repairs may be necessary.
After completing the repair, it is important to test the cord before use. Plug the cord into an electrical outlet to ensure it functions properly. If the cord works as expected, your repair was successful. However, if there are any issues, further adjustments or professional assistance may be required. Remember, safety should always be a priority when working with electrical components.

Replace the cord
If the electrical cord is heavily damaged, it is best to replace it with a new one. Before you start, make sure to shut off the electricity by switching off the fuse or circuit breaker. You can then cut the cord and separate the wires by pulling them apart.
When purchasing a replacement cord, ensure it is compatible with your appliance. You can buy a new cord from a hardware store or online. If you are unsure, seek advice from a professional.
Once you have your new cord, inspect the replacement cord cap for labels showing where each wire fits. The cord cap will have several slots with screws that hold the wires in place. Match the labels to the colour of the insulation on each wire. If there are no labels, the black power wire connects to the orange brass screw, the white neutral wire connects to the silver screw, and the green ground wire connects to the green screw. However, note that the wire colours may differ depending on your location.
After connecting the wires, make sure they are secure and will not come loose. Then, turn the electricity back on and test the appliance to ensure it is working correctly.
