its good to use, the PVC insulation is still intact.
How do you repair damaged cable insulation?
Youtube quote:Heat it with a heat gun or blow-dryer. And it will shrink to fit over the wire causing it to immobilize.
Can I use electrical tape to cover exposed wire?
Electrical tape, typically black in color, should be used on exposed electrical wires because of its low conductivity and durability to wear and tear over time. For larger gashes and cuts in electrical wires, you may need to fully cut the wire and make an electrical connection using wire nuts.
What could cause a wire to have a nick in the insulation?
Nicked insulation is often caused by a wire being pulled across the sharp edge of a metal conduit or box, when being installed.
When removing the outer casing of the cable it is important not to nick the individual wires Why?
In any electrical installation, care must be taken not to nick the conductors during the process of removing the 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.
What will happen if the 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 strip outer insulation from wire?
Youtube quote:Simply take a utility knife. And cut maybe about two inches of the sheathing then peel it back. And then you can grasp the conductor's.
Why is wire size important?
The smaller the wire diameter, the higher the resistance there will be to the flow of energy. When you have high resistance, you generate heat that can turn into a fire hazard. Proper wire size is important for any electrical wire installation. The wire size represents the diameter of the wire conductor.
Can you damage copper wire?
During the stripping process, you must avoid damaging the copper wire conductor, for it will cause electrical danger if reused. Secondly, you are required to prepare sandpapers to remove the corrosions present on the wires.
Is stripping copper wire worth it?
So is stripping copper wire worth it? Yes, absolutely if you have a wire stripper. If not, then sometimes, but most likely only if you have wires you’re sure have a high copper recovery rate.
How do you burn off copper wire insulation?
When hand-stripping your wires you can use the sun or heat to your advantage and make the process go faster. You can warm your wire in the oven (on low) or in a black box in the sunshine to warm the insulation to make it softer and easier to remove with a handheld stripper or razor blade.

What does it mean when copper wire turns black?
Normal oxidation darkens copper gradually over years, and this is observable in copper water pipes as they age. But overheated copper wires will form a dark-gray-to-black oxidation patina on the exposed wire surfaces, similar to what happens to an overheated copper pan on a stove.
How do you clean stripped copper wire?
To clean the copper wire, first, mix together 1 tablespoon of salt with 1 cup of vinegar to make a cleaning solution. Let the wire soak in the solution for 10 minutes to an hour. Then, use a nylon brush or sponge to scrub off any corrosion or dirt.
