Which electrical characteristic must be present in equipment for safety?

• A. Shockproof
• B. Grounded
• C. Non-conductive
• D. Insulated

Answer: (B)

For safety in electrical equipment, grounding is essential. Grounding provides a direct path for electrical current to flow safely to the ground in the case of a fault, such as a short circuit. This helps prevent the build-up of voltages that could lead to electrical shocks or fires. When an electrical device is properly grounded, excess electricity will follow this path rather than causing danger to users or damaging the equipment. In contrast, while the other options refer to characteristics that enhance safety, they do not provide the same level of protective grounding. Equipment can be non-conductive or insulated to prevent accidental contact with live electrical parts, but these measures do not offer a pathway for fault currents to safely dissipate. Shockproof devices might reduce the risk of electrical shock but do not replace the necessity of grounding, which is a fundamental safety measure mandated in electrical installations to protect both people and equipment.
