According to NEC Article 300.25, what are conductors required to be held in?

Conductors are required to be held in secure and stable support systems to prevent sagging or damage, as specified in NEC Article 300.25. This requirement is crucial for ensuring the safety and functionality of electrical installations. Proper support helps maintain the integrity of the conductors, avoiding physical stress that could lead to wear, disconnection, or electrical faults. By securing conductors in a stable manner, the risk of accidental contact with other surfaces, potential projectiles, or environmental factors is significantly minimized, promoting overall safety in electrical work.

In contrast, flexible support systems or temporary fixtures might not provide the stability needed for long-term installations, leading to potential hazards. While cable trays are an effective method for supporting conductors, they are just one of several compatible support systems. The emphasis in NEC Article 300.25 is on the need for secure and stable support, which encompasses a range of acceptable methods.
