Service conductors shall not be installed beneath openings through which materials may be moved and shall not be installed where they will obstruct entrance to these buildings' openings.

• A. True
• B. False
• C. Not specified
• D. N/A

Answer: (A)

The reason behind this rule is safety and reliable access. Service conductors must be protected from physical damage and kept clear of pathways and entry points. Placing conductors beneath openings through which materials may be moved creates a risk: moving loads could strike or damage the conductors, and people trying to use the door or entrance could be hindered or endangered. Therefore, the code forbids installing service conductors in that location and also forbids installations that would obstruct entrances to building openings. That’s why the statement is true.
