Which term refers to the required labeling for equipment subject to arc-flash hazards?

• A. Arc-flash hazard
• B. Warning marking for electrical equipment
• C. Enclose or separate electrical equipment
• D. Disconnecting means

Answer: (B)

The required labeling for equipment subject to arc-flash hazards is the warning marking for electrical equipment. These warning markings communicate that an arc-flash hazard exists and provide essential details such as incident energy estimates, the appropriate PPE, system voltage, and sometimes the arc-flash boundary. Standards require this labeling to help workers assess risk and choose the right protective measures before servicing equipment. The other terms describe the hazard itself, or unrelated design/operational concepts, not the labeling that must be applied to the equipment.
