True or False: Even if there are cracks in insulation, you are still protected from an electric shock.

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (B)

Insulation integrity is what keeps live parts isolated from people, forming the barrier that stops current from taking a path through you. When insulation is cracked, that barrier isn’t reliable anymore. Moisture, dust, or oils can bridge the gap, and current can creep or arc across the surface or through the damaged area. Because even small defects can create a conductive path, you’re not guaranteed protection anymore. So the statement is false: cracks in insulation raise the risk of electric shock, and damaged insulation should be repaired or replaced and the equipment de-energized before handling.
