Which tool is used to remove insulation from electrical wires?

• A. Hacksaws
• B. Pliers
• C. Wire strippers
• D. Calipers

Answer: (C)

Removing insulation from electrical wires requires a tool designed to cut through the coating without touching the conductor. Wire strippers are built for this task: they have sharp blades that cut the insulation cleanly and a stripping notch sized to the wire gauge so you can clamp, cut just the insulation, and pull it off to expose a pristine conductor without damaging the copper strands. This ensures a reliable, safe connection when you terminate the wire. Hacksaws are meant for cutting metal or hard plastics and would likely nick or slice into the insulation or reveal damaged material. Pliers are great for gripping, bending, or twisting but don’t provide a clean, controlled insulation removal and can crush or nick the wire. Calipers measure dimensions and don’t remove any material, so they don’t help in stripping insulation.
