Under NEC Article 300.37, what installations require special attention?

Under NEC Article 300.37, special attention is given to installations involving vertical rises. This is primarily because vertical runs of conductors present unique challenges and considerations related to mechanical support, potential for physical damage, and the expansion and contraction of conductors due to temperature changes. Proper securing and supporting of conductors in vertical installations are critical to prevent issues such as sagging, which could lead to damage or failure over time.

While installations involving outdoor lighting and those in hazardous locations are indeed important and may have specific requirements outlined in other sections of the NEC, the unique considerations associated with vertical rises specifically warrant the special attention described in Article 300.37. All commercial electrical service installations may have regulatory requirements, but they are not explicitly highlighted in the same way as vertical installations in this context. Therefore, the focus on vertical rises aligns directly with the safety and compliance regulations established by the NEC.
