Home / Cable trays replace grounding
Cable trays can be used as the only equipment grounding conductor (EGC), but they must meet certain criteria (only in qualifying facilities, minimum cross-sectional areas, U. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems. Cable tray grounding is an indispensable aspect of electrical installations that plays a pivotal role in ensuring safety, reliability, and efficiency. However, the main principle should always be to ensure safe and effective grounding.
