Which of the following is the correct description for the zone around a bathtub and shower where luminaire parts are restricted?

• A. 8 8
• B. 3 8
• C. 3 5
• D. 5 8

Answer: (A)

The concept being tested is how electrical luminaire parts are restricted in the bathroom area around a bathtub or shower. This zone is defined to protect against moisture and splash exposure, and the exam expresses it as a pair of numbers describing the extent of the restricted area. The best answer here uses 8 and 8 to indicate the zone extends 8 feet horizontally from the tub/shower edge and up to 8 feet high. This framing matches the idea of a broad, perimeter-restricted area around the fixture, which is why it’s chosen as the correct option in this item. The other pairs describe smaller extents (3 feet or 5 feet outward with a vertical limit), which do not align with the description of the restricted zone used in this question.
