Angle cut along the wall of the cable tray
By applying the following formula you can quickly find the size of the cut-out section that you need to cut out of the side of the cable tray, or gutter-type section to make that angle. First, you have to find (C) which is found by dividing 90° by (B) 22° = 4. Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation space. Cable tray system design shall comply with National Electrical Code® (NEC® ) Article 392, NEMA VE 1, and NEMA FG 1 and follow safe work practices a described in NFPA 70E. Further, it is recommended that installers follow all guidelines and best practices found in NEMA VE 2. Use side action bolt cutter to prevent sharp wires from protruding past the cut intersection. Angle cuts beyond cross wire (See Offset Cut image below).
