Which installation is considered outside a building?

• A. II only
• B. III only
• C. II & III only
• D. I, II, & III

Answer: (C)

The key idea is where the equipment is located relative to the building envelope. Installations outside the building are those placed outdoors or in weather-exposed locations, requiring weatherproof or damp-location rated components and different protection considerations than indoor work. In this set, two installations are located outdoors, while one is inside. Since outside installations are the ones that are exposed to the elements, the correct choice is the option that includes both outdoor items.
