What term describes where a raceway from an underground distribution system enters a building, it should be sealed?

• A. Where a raceway from an underground distribution system enters a building, it should be sealed
• B. The process of setting up a lamp holder in an outdoor environment
• C. The recommended positioning of lamps in relation to electric utilization equipment
• D. The least distance that must be maintained between two open conductors

Answer: (A)

Sealing the entry point where an underground raceway enters a building is required. This keeps moisture, dust, and pests out and helps preserve the integrity and fire resistance of the enclosure where the raceway transitions from underground to indoor space. The statement that this entry should be sealed directly captures that requirement, making it the correct choice.

The other topics described—installing a lamp holder outdoors, positioning lamps relative to equipment, and the minimum distance between open conductors—relate to different aspects of electrical work and do not address sealing at a raceway entry.
