According to NFPA 70-2017, how far can other associated equipment extend beyond the front of electrical equipment?

The correct answer is 6 inches. This specification is outlined in NFPA 70 (National Electrical Code), which governs safe electrical installations. NFPA 70-2017 establishes guidelines for the placement and extension of equipment associated with electrical installations, including how far additional equipment can extend in front of electrical equipment.

Allowing associated equipment to extend no more than 6 inches helps ensure safety by minimizing the risk of obstruction, ensuring access to vital components, and maintaining adequate clearance for equipment operation and maintenance. Such regulations are put in place to consider the safety of personnel working around electrical installations and to prevent interference with other equipment or hazards.
