Safety First: Before undertaking repairs, always unplug the light from the electrical socket. This is crucial for preventing electrical shock.

Locate the old plug

First, find where the old plug is attached to the end of the lamp's power cord. It's usually right there at the end.

Remove any screws

Look for any screws holding the old plug in place; these screws are typically small and easily accessible. Your trusty screwdriver will make quick work of them.

Gently pull the old plug away from the cord, being careful not to pull on the wires themselves. You may need to use wire cutters to snip the wires if they are tightly connected.

Inspect the cord

After disconnecting the wires, you Check the lamp's power cord for damage, such as fraying or cracking. If the cord is damaged, it may be necessary to replace both the cord and the plug.

Step 3: Prepare the Wires for the New Plug

Measure the cord 

Determine the length of the cord that needs to pass through the new plug. This will assist ensure a good fit.

Strip the wires

Firstly, to begin replacing the plug, use a utility knife to cut off the old plug and about 1 - 2 inches (2.5 - 5.1 cm) of the cord. Measure down from the plug and make a straight cut through the cord to avoid fraying the wires. Once cut, discard the old plug immediately. If you find it challenging to cut with a utility knife, scissors can be a good alternative.

Opening up the cord's sheathing about 1.5 - 2 inch

When preparing the wires for a new plug, carefully open the outer wire sheath about 1.5 to 2 inches. Use caution to avoid nicking the inner wires. Once the sheath is opened, gently peel it off to expose the individual wires inside. Next, trim off any excess sheath material carefully.

Remove 1/2 inch (1.3 cm) of insulation from each wire using wire strippers

To strip a wire, start by using wire strippers to grip one of the wires about half an inch away from the end. Pull the strippers toward the end of the cord and squeeze the grips together to remove the insulation. Discard the insulation piece that comes off. Repeat this process for the other wire so that both are exposed. Make sure you strip the third wire on your lamp if it has one for grounding.

Identify the wires

Examine the wires and determine which one is the live wire (usually brown or black), the neutral wire (usually blue or white), and the ground wire (usually green or bare copper). 

However, it is sometimes difficult to determine wires because each manufacturer will have different color regulations. To be sure, you can read our guide on ways to identify which lamp wire is hot, neutral wires

Twist the exposed wires' frayed ends to make them easier to attach

To make it easier to connect the wires, twist the frayed ends together so they become a single solid wire. Hold one wire end and twist the frayed parts clockwise. Repeat this with the other wire. Do not twist the two wires together as this will make connecting them to the plug later on more challenging.

Step 4: Connect the Wires for the New Plug

Insert the cord through the plastic plug cover

Gently pull the two lamp wires through the opening in the cover by holding them together. After covering the wires with the cover, draw them through to the opposite side. Keep the cover positioned about 3 - 4  inches (7.6 - 10.2 cm) away from the cord's end to avoid hindering your work. If your new plug has a hinge rather than a separate cover, you can omit this step entirely. This ensures a smooth setup and proper alignment of all components.

Connect the wires

Shape the wire into a small hook and place it under the silver screw on the replacement plug's prongs, ensuring the wire wraps around clockwise. 

Carefully insert each wire into the corresponding terminal on the new plug, ensuring a secure connection. The live wire goes to the brass or gold terminal, the neutral wire goes to the silver terminal, and the ground wire (if present) goes to the green or bare terminal.

Secure the wires

If you spot any such issues near the plug connection - or elsewhere - wrap these areas with high-quality electrical tape for additional reinforcement. 

Step 6: Test the Lamp to Ensure It Is Working Correctly
