For support purposes, cable wiring methods should NOT be used to support which of the following?

Cable wiring methods are designed primarily for the installation and management of cables, and they can have specific limitations when it comes to supporting other types of equipment or structures. When it comes to using cable wiring methods for support, it is essential to adhere to the guidelines set forth in the National Electrical Code (NEC) to ensure safety and compliance.

In general, cable wiring methods are not suitable for supporting raceways, non-electrical equipment, or other cables because these methods do not provide the necessary mechanical strength or stability required for such uses. Raceways, for example, have their own specified support requirements to maintain integrity and protect the conductors within them. Similarly, non-electrical equipment could exceed weight or stress limits that cable support methods are not designed to accommodate. Supporting other cables may also lead to improper tension and stress on the cables, which can result in damage or create hazards.

Therefore, it is crucial to follow proper support guidelines for each type of system, ensuring that installations meet all safety standards and effectively protect all components. This adherence is essential for maintaining the safety, function, and longevity of electrical installations.
