The specification for the highest operating handle position is found in which table?

• A. Table 312.6 (B)
• B. Table 408.56
• C. Table 517.14
• D. Table 404.8

Answer: (A)

The key idea here is where the NEC specifies how high the operating handle can be positioned on enclosures and the equipment within them. That detail is provided in the table that covers boxes, cabinets, and fittings, including mounting heights and operating clearances. Table 312.6(B) is the specific table that lists the maximum handle heights for enclosure-mounted devices, ensuring operators can reach and operate the handle safely without risk of overreaching or interference. The other tables address different topics: 408.56 relates to panelboard and switchboard arrangements or ratings, 517.14 covers hospital facilities and patient-care areas, and 404.8 deals with switching for circuits rather than the physical height of the operating handle. So the highest operating handle position specification is found in Table 312.6(B).
