What size should the holes for cable trays be
The 2026 NEC introduced an important update: cable trays must have at least 12 inches of clear vertical space above them to allow for installation and maintenance access. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. For many installations the power cables will exit out the bottom of the cable tray and into the top of the equipment.

How to ground the cable tray in the low-voltage electrical shaft
By bonding the tray system every 50' -60' the tray will maintain a low potential to ground which reduces external electrical and magnetic disturbances and provides a continuous path for stay currents. Their open-grid design makes it easy to route, add, or modify cabling. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety. It involves connecting cable trays to the facility's grounding system, providing a low-impedance path for fault currents and protecting personnel. In addition to simply routing and protecting cables a cable tray system must provide protection to life and property against faults caused by electrical disturbances, lightening, failures which are part of the system, and failures of equipment that is connected to the system. This grounding creates a safe pathway for fault.
