Where do we use electrical tape?

• A. Nowhere
• B. On splices
• C. On insulation
• D. On connectors

Answer: (A)

Electrical tape is used to insulate exposed conductors after a splice. When two wires are joined, there are bare strands that could short against other conductors or moisture could enter the splice. Wrapping the splice with electrical tape provides additional insulation, helps seal out moisture, and adds a layer of strain relief until a more permanent repair (like a properly rated splice or heat-shrink cover) is installed. It isn’t primarily used to cover intact insulation or to seal connectors, since those cases rely on the wire’s insulation or the connector’s own sealing features. So the main use is on splices to keep the splice insulated and protected.
