In attics with servicing equipment, the lighting outlet switch must be installed at which location?

• A. At the usual point of entry to the attic
• B. Near the equipment
• C. In the living area
• D. In the basement

Answer: (D)

When you have equipment in an attic, the lighting for that space should be controlled from a location that’s readily accessible before you go up to service the gear. Placing the switch in the basement fits this goal: you can turn on the attic light from the basement stairs or entry area, giving you light for a safe, prepared ascent and making it easier to work without groping in the dark. It also keeps the switch out of the attic where heat, dust, or frequent climbs could affect it.

Why the other options aren’t as good: putting the switch at the usual attic entry would require you to reach the attic first to get light, which isn’t ideal when you’re preparing to work there. Locating the switch near the equipment can expose it to heat or clutter and makes it less convenient if you’re initiating the task from below. Putting it in the living area is even less practical since it’s far from the attic access and wouldn’t be immediately usable when you’re about to go up.

So, the basement location provides the safest, most practical control point for attic servicing lighting.
