Also question is, do you have to use electrical tape?

Use Only on Minor Cord or Wire Damage If the cord has cracked or nicked outer sheath, but the inner insulation is still intact, then electrical tape can be used as a safe repair option. However, never cover an electrical tape wire repair with a rug, cloth, or other flammable material.

Beside above, what is the purpose of electrical tape? Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics, but vinyl is most popular, as it stretches well and gives an effective and long lasting insulation.

Keeping this in view, can I use regular tape instead of electrical?

The big difference between electrical tape and "regular" adhesive tape is that electrical tape is stretchy. This allows the tape to wrap around a wire junction and still grab the insulation to either side. Regular tape is likely to get stiff, lose adhesion, and slide away from the joint, leaving it exposed.

Can electrical tape catch fire?

Even though most of the reputable brands produce electrical tapes with good thermal properties that can handle temperatures around 80 degrees Celsius, electrical tapes are likely to catch fire if they get very hot. The chances of combustion are reasonably low when the tape is used properly and in the right environment.
