Which term covers methods to prevent contact with live parts for equipment operating at 50 to 1000 volts?

• A. Arc-flash hazard
• B. Accidental contact prevention
• C. Enclose or separate electrical equipment
• D. Maximum available fault-current

Answer: (B)

The main concept here is accidental contact prevention—the set of methods used to keep people from touching live parts when equipment operates from 50 to 1000 volts. This includes shielding, barriers, enclosures, insulation, interlocks, and safe work practices that physically separate or isolate live components from accessible parts. This term best fits because it focuses on preventing contact with live parts, rather than on the energy that might be released in an arc (arc-flash hazard), a single method like enclosing equipment (which is just one approach), or the magnitude of fault current (maximum available fault-current).
