NEC Article 300.35 concerns conductors supported where?

The correct answer pertains to NEC Article 300.35, which specifically addresses where conductors may be supported in certain types of construction. This section indicates that conductors can indeed be supported in cinder block or masonry constructions. This context is important because it illustrates the practical application of support methods for electrical conductors in environments where structural integrity and compliance with safety standards are paramount.

Supporting conductors in cinder block or masonry construction is permitted under the NEC as these materials can adequately support the necessary electrical infrastructure, provided that all other NEC requirements and local amendments are met. This ensures that conductors are installed safely, reducing risks of damage or hazards.

Constructions such as wooden structures, commercial buildings, or underwater installations have distinct electrical code requirements and considerations. Therefore, their specific applications do not directly relate to this particular article, which focuses on the structural capabilities of masonry support for conductors.
