Spacing of cable tray supports in fire shafts
Short Span trays, often used for non-industrial indoor installations, are typically supported every 6 to 8-feet, while Intermediate Span trays are typically supported every 10 to 12-feet. Scope: Firestopping for busway, cable trays, cables, and trunking passing through walls in enclosed electrical installations. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable su...
