Possible Reasons for Nicked Electrical Wire

If you are noticing a nick in an electrical wire, then you may have incurred the following:

Accidental Nicking:

The most common cause of nicking wires will be accidentally when cutting through thick or tough material such as wood and metal, using the wire cutter, scissors, and so on.

Natural Causes:

Over time, as plastic electrical wires are used and then exposed to the sun and moisture, it can cause short circuits or nicks.

Impact Damage:

Another probable reason why you would find a nick in an electrical wire is due to impact damage such as dropping a heavy object on a power cord or flexing the cable repeatedly moving it about from room to room.

Rotting:

If the wiring is exposed to moisture, over time, it can rust and even nick the wire making a short circuit in some instances, which could damage electrical appliances that are switched on or plugged into sockets with nicked wires as part of their power cable.

Improper Installation:

An electrician may accidentally nick a wire while pulling through a cable or flex when passing it through the walls of your home.

Domestic Violence:

You might have found nicked wires at your home due to domestic violence where there could be damage caused to the cables internally or externally, which will need to be repaired.

Instructions: How to Fix a Nicked Electrical Wire 

Steps One:

How to Fix a Nicked Electrical Wire 

First, you need to identify the location of where the electrical wire is nicked.  The sooner you identify the problem and attempt to fix it, the better. In this case, you will need to cut away any wire that is damaged immediately. Once done, secure the area with electrical tape or a spiral wrap cover. This will prevent any short-circuiting that may occur if you are to continue using the cord.

Step Two:

Fix the broken or damaged wire with a new piece of electrical wire. Cutaway any exposed strands of wire and push back on the strand into the rest of the cord to prevent future damage. Make sure that you use the same gauge as your existing wire; otherwise, this could be problematic in itself.

Step Three:

After repairing all breaks or nicks, it is now time to re-attach the cord to the plug. Then, simply push the wires into place and secure them with electrical tape or a spiral wrap cover. Make sure that you check for any exposed strands of wire before attempting this step.

Step Four: 

Make a final check to ensure that no strands of wire are exposed. If so, you can cut them away and secure the area with electrical tape or a spiral wrap cover. Then use your screwdriver to tighten the connections at both ends of the cord. Ensure that they are tight enough to prevent any possible loose connections but not so tight as to break the wires.

Step Five:  

Now it is time to test the cord out. Make sure that you are wearing your safety glasses and using caution when testing out the cord. Plugin the cord and turn on any appliances that will be connected to it. Ensure they are working properly before putting them into regular use.

Precautions To Take

  • Never Pull from the Wire but always Push your Cutter or Stripper in a Counter Clockwise Motion.
  • Always Keep Wire out of the Reach of Children and Animals to Avoid Accidental Electrical Shock or Fire Hazard but Read below if you have an already damaged Wire. Repairing Damaged Electrical Wires is possible.
  • Never Extend the Wire or Wires Over Head to increase the Risk of Electrical Failure.
  • Always Use a 3-Pronged Ground Plug for Protection Against Electrical Shock, but if you have a Nick in your Wire already, you must repair it first before using it again.
  • If you have a Nick in your Electrical Wires, then there is at least a 1% risk of Electric Shock or Fire, so be very careful when repairing this damaged wire.
  • Always Screw your Light Socket or Outlet in the Clock Wise Motion.
  • Always Unplug all of Your Electrical Devices before starting any repairs on them.

How Do You Fix Nick in Wire Insulation?

If you nick wire insulation, and it doesn’t go completely through the insulation, but there is a hole where you might be able to see the copper wire, do not panic. This nick does not have to cause any problem unless you are planning on inserting that wire into an electrical outlet or switch.

The reason for this is because although the nicked insulation may look bad, it will not provide an egress path for electricity because of the rubber tubing surrounding the wires. In addition to that, if your skin contacts nicked line carrying live current, your body resistance would immediately trip the circuit breaker; if not worse, stop electricity from flowing through your body, preventing injury.

Conclusion

In conclusion, if you have a nicked wire in your home, there are some steps mentioned in this blog on how to fix a nicked electrical wire that will help resolve the issue. It is important to fix nicked wires because they can lead to a fire. One way to do this is by using an electrician’s tape or electrical insulation kit.
