The table that governs clearances for conductors up to 22 kV to ground over buildings is Table 225.61. This table applies to which locations?

• A. Buildings and other structures
• B. Underground tunnels
• C. Inside the building rooms
• D. On the roof only

Answer: (A)

The main idea here is about overhead clearances for electrical conductors up to 22 kV when they pass over built-up areas. Table 225.61 specifies the minimum distances to ground that must be kept when conductors run over buildings and other structures. That means it applies to any location where the wires cross above a building or structure, not just a particular surface or space. It isn’t about conductors inside buildings, nor about conductors in underground tunnels. It also isn’t limited to being on a roof only; it covers any situation where the line is over a building or structure. So the applicable locations are buildings and other structures.
