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.
