What You'll Learn
Ensure the cord is unplugged and no electricity is running through it
When attempting to fix a male electrical cord, it is crucial to prioritize safety by ensuring that the cord is unplugged and no electricity is running through it. Here are some detailed steps to achieve this:
Completely Unplug the Cord: Start by disconnecting the male electrical cord from any power outlet or device it is connected to. Ensure that the cord is entirely unplugged before proceeding. Avoid touching any exposed metal wires or contacts during the unplugging process.
Shut Off Electricity at the Source: If the cord is heavily damaged or if you are unsure whether it is completely turned off, consider shutting off the electricity at the fuse box or circuit breaker. This will guarantee that no electricity is flowing through the cord during your repair work.
Inspect the Cord: Before beginning any repair work, carefully inspect the cord for any signs of damage. Look for broken wires, exposed wires, or damage to the insulation. Feel the length of the cord to detect any unusual warmth, which could indicate an electrical issue.
Verify with a Voltage Tester: To ensure absolutely that there is no electricity running through the cord, use a voltage tester. Place the tip of the tester on one wire and its body on the other wire or onto a ground, such as a water pipe. If it lights up, electricity is still present; if not, it's safe to proceed.
Safety Precautions: Working with electricity can be hazardous, so take all necessary precautions. Never handle live wires, and ensure you are in a dry area to avoid the risk of electrical shock. Consider having a buddy nearby who can assist or call for help if needed.
By following these steps, you can ensure that the male electrical cord is unplugged and free of any electrical current, allowing you to proceed with repair work safely.

Inspect the cord for damage and mark any damaged areas
Before attempting to fix a male electrical cord, it is important to inspect the cord for damage and mark any damaged areas. This is a crucial step to ensure safety and identify potential issues. Here are some detailed steps to guide you through the process:
Begin by disconnecting the cord from any power source. Ensure that it is completely unplugged by checking that there is no electrical current running through it. This is an important safety precaution to avoid the risk of electrical shock. If the cord is heavily damaged, consider shutting off the electricity by switching off the fuse or circuit breaker.
Once the cord is safely disconnected, start your inspection by looking for any visible signs of damage. Check for fraying, cracks, or exposed wires. Exposed wires can pose a serious hazard and indicate a potential issue with the cord. Feel the entire length of the cord to detect any unusual warmth, which could suggest internal damage or overheating.
Pay close attention to the insulation of the cord. Look for breaks or damage to the outer insulation, as this can compromise the functionality of the cord and increase the risk of electrical fires. Inspect the plug prongs as well, and be on the lookout for any signs of melting or burning.
As you identify areas of damage, make sure to mark them clearly. This can be done using tape or any other suitable marking method. Marking the damaged areas will make it easier for you to locate them later during the repair process, ensuring that you don't miss any spots that require attention.
By thoroughly inspecting the male electrical cord and marking the damaged areas, you can make informed decisions about the necessary repairs and ensure that the cord is safe to use after fixing. Remember to prioritize your safety throughout the entire process.

Cut off the damaged part of the cord
Before you start, make sure the electrical cord is unplugged from the outlet. If the plug is still in the outlet, turn off the power at the breaker before unplugging. You should also shut off the fuse or circuit breaker if you're dealing with heavily damaged cords. Detach any other cords or electronics that are connected to the wire.
Now, cut off the damaged part of the cord with electrical scissors, wire cutters, sharp shears, or cutting pliers. If the damage is close to the plug, cut the cord at the damaged spot. If the damage is in the middle of the cord, you will have two shorter cords. If you're working with vintage appliances, be aware that antique and vintage appliances often have fabric-covered power cords. The insulation in old cloth wiring deteriorates over time, increasing the fire hazard. Asbestos was used as an insulator in appliances made before the 1980s, so cutting into a cloth cord could release asbestos fibres into the air.
Once you've cut off the damaged part of the cord, you'll need to strip the wires and splice them together, making sure the wire colours match or that you match the ridge side with the smooth side. You can twist the copper strands together and cover the wires with electrical tape, but it's more secure to solder the wires together and then cover them with electrical tape. Solder is a type of metal used to join wires together, and a 63/37 solder wire is made of 63% tin and 37% lead, which melt at a relatively low temperature for a quick but strong fix.
Finally, cover the repaired area with a PVC shrink tube and shrink it with a heat gun.

Strip the wires and match the wire colours or ridge and smooth sides
Before you start repairing an electrical cord, it's important to disconnect the cord from the outlet. Make sure the cord is completely unplugged and that the non-damaged end is also unplugged. If you're dealing with heavily damaged cords, consider shutting off the electricity first by switching off the fuse or circuit breaker.
Now, let's focus on stripping the wires and matching their colours or ridge and smooth sides. First, you'll need to cut away the damaged part of the cord with cutting tools such as electrical scissors or wire cutters. Ensure you cut through all the insulation and wiring in one attempt to create a clean cut.
Next, use wire strippers to strip about 0.5 to 0.75 inches (1.25 to 1.9 cm) of insulation from the end of each wire. Be careful not to damage the wires underneath. The amount you strip may vary depending on your terminal screw setup, so refer to the replacement plug's strip gauge if available.
Once the wires are stripped, you'll need to twist the strands into tight points and then match them correctly. If the wires are colour-coded, twist the wires of the same colour together, keeping the colours separate. For example, twist the red wires together and then do the same for the blue wires.
If your wires do not have colour coding, they will have ridge and smooth sides to help you match them correctly. The wire with the ridge on the outside is the return or neutral wire and goes to the silver-coloured screw. The smooth wire is the hot wire, carrying the electrical current, and it goes to the brass-coloured screw.
By following these steps, you will have successfully stripped the wires and matched their colours or ridge and smooth sides when fixing a male electrical cord.

Attach a new plug with matching amperage and voltage ratings
Before you start, make sure the device is unplugged and that you are not touching any exposed wires or contacts. If the cord is heavily damaged, consider shutting off the electricity first. You can do this by shutting off the fuse or circuit breaker.
Now, inspect the cord for any signs of damage. Look for breaks in the insulation, or check the plug prongs for any signs of melting or burning. If the damage is close to the plug, you can cut the cord at the damaged spot. If there is damage to the cord close to the plug, trim those parts off as well. The cord should be smooth and undamaged all the way to the end where the plug goes.
When choosing a new plug, it is important to make sure it has the same amperage and voltage ratings as the old one. The number should be printed on both the old and new plugs, so make sure they match. Don't replace a three-prong plug with a two-prong plug or vice versa. If you're replacing a polarized plug, make sure the new plug is polarized too.
To attach the new plug, use electrical scissors, wire cutters, or sharp shears to cleanly cut the old plug off the end of the power cord. Open the new plug housing by unscrewing it with a Phillips-head or flat-head screwdriver. Pull and wiggle the plug open and set the screws aside. Thread the cut end of the cord through the plastic cover. If you have a self-connecting plug, align either side of the cord with the side of the wiring channel marked with a "W". Insert the cord through the assembly clip and into the wiring channel up to the cord-stop ribs.
