What is electrical tape?

Black Vinyl Insulating Electric Tape On The White BackgroundFor many of us, electrical tape can be found in that drawer that has everything, right next to the screwdriver, pliers and duct tape. But you might be wondering what exactly makes electrical tape different from the rest of the tape family?

Since its invention in the 1940s, electrical tape remains one of the most common ingredients to simple electrical jobs around the house. Its ability to keep electrical current from passing through it, makes it an essential insulator, to not only keeping wires from touching and shorting out, but also from a live wire being accidentally touched by someone.

How to use electrical tape

Electrical tape is wrapped around minor wire or cord damage to give it the insulation it needs and the strength it requires. As you wrap the tape, pull on it slightly so that it fits snug, and no space is left uncovered. Vinyl is the most commonly used substance for the making of electrical tape because of this stretching ability. Remember electrical tape is meant for repairing minor electrical wire damage. You should always consult a professional electrician if you are unsure of the proper usage.

Electrical tape colors and strength

Black is the most common color. Its ability to stand up to UV rays, makes it the tape of choice for all jobs in direct sunlight. White tape is sometimes used to indicate neutral wires, and green or yellow for grounding wires. No matter what the color, electrical tape is very strong. It is made to last, does not tear easily, and stands up to corrosion.
