Nicked (or stretched) conductors reduce the conductors diameter in a localized area. Depending on the actual damage it may not cause heating at the location under normal load conditions however the mechanical strength of the conductor has still been compromised and flexing near this area could weaken it to a point where the conductor could fracture and fail.
What causes a Nick in an electrical wire?
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. Once you have a nick in the insulation on your electrical wire, the copper conductor is exposed.

Can you fix a nicked wire with electrical tape?
If the insulation on the wire has been accidentally snipped, then you can make a repair using electrical tape. If the wire has been cut, so it's in two pieces, the electrical tape will not be sufficient to attach the two pieces of wire.

What happens if you nick wire insulation?
If the wire is nicked, one of two things may happen: *The nicked conductor is no longer capable of carrying its rated amount of current through the damaged portion. If the nick is deep enough, the wire will overheat at the nicked point.
What happens if wire insulation is damaged?
Worn, frayed, or damaged insulation around any wire or other conductor is an electrical hazard because the conductors could be exposed. Contact with an exposed wire could cause a shock. Damaged insulation could cause a short, leading to arcing or a fire.
How do you fix damaged insulation?
The most professional repair for wire insulation involves heat shrink tubing. As long as you can disconnect one end of the wire, you can simply slip a piece of tube over the wire, reconnect the other end, and then apply a heat to the tube with a heat gun or even a common hair dryer.
Does Nick mean cut?

Why do wires nick?
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.
How to fix a broken wire?
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.
How to tighten electrical wires?
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.
Can you fix a nicked wire?

The greasy stuff may be caused by humidity inside the wall due to a lack of insulation, or it may be coming from plumbing pipes in the wall that may be above the electrical wiring. The electrical cable may become warm when it is used and if the inside of the wall cavity is cool this can create a certain amount of moisture or condensation to form.

Why is my electrical wire broken?
Many electrical problems can be traced back to a poor or broken splice in conductors, and many times the problem is a broken wire resulting from damage caused to a conductor from improper stripping methods. Even if a nick in the wire doesn’t result in a complete break, compromising the integrity of the wire can impede the flow of electricity at that point.

What causes a wire to break off?
It is possible that the nicked area of the wire conductor may break off preventing current flow or even possibly shorting with another conductor, or the conductor cold make contact with the grounded box enclosure and cause a direct short to ground which would cause the circuit breaker to trip off or cause a fuse to blow. This is assuming that the circuit is properly sized and protected by the correct protection device.
How to tell what gauge wire is used?
