Why are electrical outlets covered with plastic?

Answer 1

so you won't get burned

===========

It serves as an electrical insulator to protect your from shock and the wires from shorting, and when placed near the ends (as a boot) it serves as a strain relief to protect the cord from pulling out of the device.

Answer 2

The plastic around the wire is to protect yourself from being electricuted when the wire is plugged in.

of course but its main purpose is to protect the wire from various destruction and deformation due to natural and man made hazards.

Answer 3

As far as I know, wires are wrapped to protect them from the weather and rust. The platic protection are used to reinforce the wire's durability and prevent it from losing electrical tension.

The very first reason they are coated is to minimize the chance of shorting out with other conductors. The coating protects the wire from shorting against a metal ground or other wires and objects.

Answer 4

As with any cable or cord set the outer jacket is used to protect the inner current carrying conductors. Jackets are made of various hard wearing materials depending on the type of location and duty use the cords and cables will be subjected to. The wires are covered with insulation to stop them from shorting out between themselves and between themselves and ground.

Answer 5

To protect occupants from accidental electric shock. Plastic is cheap and it does not conduct electricity.
