How to Replace a Plug on a Power Cord

What You Will Need:

Scissors or wire cutters
Wire strippers or a sharp penknife
Spare power cord
Electrical tape

1. Cut the bad plug off its cord and throw it away.

2. Find a power cord that you aren’t using. Maybe it’s from an old printer, maybe it’s an old extension cord. Cut the plug off this spare cord, leaving about 6 inches of cord attached. Throw away the rest of the cord.

3. Slice the old cord down the middle about 4 inches in so that you have two sections of cord. The wires are beneath the plastic coating, encased in rubber.

4. Carefully strip about an inch and a half of plastic and rubber casing off the wires using wire strippers or a penknife. The wires are generally copper and consist of tiny individual copper threads. Be careful not to cut the wire itself.

5. Repeat steps 3 and 4 on the new section of cord.

6. Twist tightly together one wire from the new cord and one wire from the old cord, then repeat with the remaining wire from each cord.

7. Neatly tape over each joined wire with electrical tape. Start an inch before the wire and continue wrapping the tape an inch past the wire. Use two layers of electrical tape over each wire section.

8. Neatly tape both sections together with electrical tape. Start taping from the plug end, about an inch before the split. Continue taping the sections together, stopping about an inch past the split on the old cord. Use two layers of electrical tape. The goal is to end up with a single cord again.
