According to NEC Article 300.4, what must be done when conductors are in contact with framing members?

When conductors are in contact with framing members, it is essential to protect them from physical damage. This requirement is outlined in NEC Article 300.4, which addresses the need for proper installation practices to ensure the safety and reliability of electrical systems. The framing members, typically made of wood or metal, can create potential hazards such as abrasion or impact that may damage the insulation of the conductors.

This protection can often be achieved through the use of conduit, protective plates, or appropriate cabling methods that shield the conductors from any physical stress that could lead to failures or electrical hazards. Ensuring that conductors are safeguarded against physical damage is crucial for maintaining the integrity of electrical installations and preventing dangerous situations such as electrical shorts or fires.
