What is insulating tape?

• A. Conductive tape
• B. Rubber tape
• C. Non-conductive adhesive tape
• D. Magnetic tape

Answer: (C)

The main idea is recognizing what insulating tape is used for in electrical work: a non-conductive adhesive tape designed to insulate conductors and prevent current from leaking or shorting.

Insulating tape is typically vinyl electrical tape with a non-conductive backing and adhesive, crafted to stick to wires and cover exposed conductors. This non-conductive nature makes it safe for wrapping electrical connections and splices, helping to prevent shocks and shorts and to withstand some heat and moisture.

Conductive tape would create a path for current, which defeats insulation. Magnetic tape is for data storage, not electrical insulation. Rubber tape exists in various forms, but the standard category used for electrical insulation is non-conductive adhesive tape. That’s why it’s the correct choice.
