Calculation of distance from cable tray bend to wall
Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation space. Measure this distance along the straight tray. Two Bends Per Offset: Every offset requires two equal bends — one to move laterally and one to return to parallel. The total tray section consumed = 2 × single bend length. Pre-fab vs Field Bent: For standard offsets (6, 12, 18 in at 45°), use manufacturer pre-fabricated offset fittings to save. When installing two cable trays in parallel at the same height, the distance between them should be no less than 0. This spacing is crucial for adequate maintenance access, ease of inspection, and ensuring proper airflow for effective heat dissipation. ) that matches or exceeds this value. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support.
