According to NEC Article 300.17, what must be considered for cable supports?

According to NEC Article 300.17, when selecting cable supports, it is crucial to consider the weight of the cables and their supports. This is important because the supports must be adequately designed and installed to handle the load without sagging or failing over time. Failing to account for the weight could lead to sagging, increased strain on the cables, and potentially hazardous conditions.

While other factors, such as the type of insulation and proximity to power lines, might influence different aspects of installation, they are not the primary focus under Article 300.17 regarding supports. Therefore, understanding the weight requirements ensures that the structure maintains integrity and safety throughout its operational life.
