How must DC conductors be routed according to the NEC for PV systems?

In photovoltaic (PV) systems, DC conductors must be routed and secured to prevent physical damage as outlined in the NEC. This requirement is crucial for ensuring the safety and reliability of the electrical system. Properly securing the conductors helps to protect them from environmental factors, accidental contact, and other hazards that could lead to shorts, failures, or fire risks.

By adhering to this practice, installers can minimize the risk of wear and tear on the conductors, which can result from movement, abrasion, or exposure to harsh conditions. Such measures promote the long-term integrity and performance of the PV system, ensuring it operates efficiently and safely throughout its intended lifespan.
