What is the focus of NEC Article 300.36?

The focus of NEC Article 300.36 is indeed on the integration of conductors within building foundations. This article provides guidelines for installations where conductors are embedded in concrete or in other materials of a building's foundation. It addresses concerns about the proper placement, protection, and conditions under which conductors can safely operate when incorporated into structural components.

The importance of this article lies in its requirements for ensuring that electrical conductors are not subjected to physical damage and have sufficient insulation and clearing from moisture or other deteriorating factors that can arise in such installations. Effective installations contribute to fire safety and the long-term reliability of electrical systems within buildings.

The other choices address different aspects of electrical installations regulated by other parts of the NEC, focusing on conductor separation, testing practices, and protection for overhead conductors, but they do not pertain to the specific requirements outlined in Article 300.36 regarding embedded conductors in building foundations.
