Which phrase best describes the concept of workspace around electrical equipment with exposed, energized parts?

• A. Specifications for workspace around electrical equipment with exposed, energized parts
• B. The color coding of insulation
• C. The number of service disconnects
• D. The placement of service panels

Answer: (A)

The concept being tested is the area around electrical equipment where live parts are exposed and pose a risk, requiring defined space and access for safe work. The best phrase is the one that directly names this area and its safety implications: specifications for workspace around electrical equipment with exposed, energized parts. This matches the idea of setting clear dimensions, access, and safety measures to perform work safely on or near live components. The other topics—color coding of insulation, the number of service disconnects, and the placement of service panels—do not describe the safe workspace or clearance around energized parts.
