What can help protect against electrical shock?

• A. Using insulation on all wiring
• B. Grounding all equipment with exposed conductive parts
• C. Installing more circuit breakers
• D. Using thicker conductors

Answer: (B)

Grounding all equipment with exposed conductive parts is a critical safety measure in preventing electrical shock. Grounding creates a direct path for electrical faults to flow safely into the earth, rather than through a person who may accidentally come into contact with the equipment. This is especially important for devices with exposed metal parts that could become energized due to a fault. The grounding system ensures that in the event of such faults, circuit breakers will trip, thereby cutting off the electrical supply and significantly reducing the risk of injury from electric shock. Insulation on wiring, while beneficial, primarily serves to prevent the current from escaping the conductors and does not provide a path for fault current to ground. While circuit breakers are essential for protecting circuits from overloads and short circuits, they do not specifically prevent shock from equipment with exposed conductive parts. The use of thicker conductors can improve current-carrying capacity but does not address the risk of electric shock directly. Thus, grounding remains the most effective protective measure against electrical shocks in situations involving exposed conductive parts.
