What is the purpose of using rubber sheeting in electrical work?

• A. To cover floors.
• B. To decorate panels.
• C. To insulate pipes.
• D. To provide insulation and protection around energized conductors.

Answer: (D)

Rubber sheeting is used to create a non-conductive barrier around energized conductors. Its dielectric strength means it resists current passing through, which helps prevent shock, arcing, and accidental contact with live parts. By placing rubber sheeting around or over exposed energized surfaces, you establish a protective insulation layer that keeps workers safe and maintains proper clearances in electrical work. It isn’t intended for decorative purposes, floor coverings, or piping insulation, which don’t address the need to isolate live parts and protect people from electric shock.
