electrical insulation
Current flow barrier
Electrical insulation is material that resists the flow of electric current, used to prevent unwanted contact between conductors or between conductors and people.
Rubber, plastic, glass, and ceramic are common insulators.
Wires are wrapped in insulation; outlets and switches have insulated housings.
The term also describes the practice of applying such materials: The electrical insulation in older buildings often needs replacement.
