To prevent water from entering service equipment, service-entrance conductors must

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

Answer: (A)

The idea here is to keep water out of the service equipment by creating a moisture-tight path for the service-entrance conductors from the outside to the cabinet. That means using weatherproof enclosures and fittings, routing the conductors through approved raceways, and sealing every entry point (such as where the conductors enter the service equipment or a weatherproof enclosure) so that water cannot penetrate. These measures directly prevent water intrusion and ensure the equipment inside remains dry and safe. The correct option is the one that includes the two measures that provide this moisture barrier, since any item that doesn’t contribute to a watertight path wouldn’t address the water-entry risk.
