You can buy a manufactured 90 degree bend or make one on a cable tray bending machine but in this video I show you how to make one using a metal bar. Since the jaws of the bolt cutter drags a layer of zinc across the cut end and forms a protective layer. Depends on the type of cable tray, you can buy 90° tray fittings or use a speed square with a straight edge and a grinder or skill saw to cut 45° cuts. Construction of a flat 90° bend (A) The amount of tray lip to be removed is equal to 2, 3/4 the width of the tray, half of this measurement will be removed on either side of the centre line.

This means routing must be through dedicated, fire-resisting cable support systems – no sharing trays. This guidance covers the routing of secondary supply cables from a life safety generator to the ATS (Automatic Transfer Switch), and the final equipment with reference to: The goal: clarify requirements for the diverse cable routing and maintain circuit integrity under fire conditions for systems. Zip-tying or wrapping low-voltage cabling (data, access control, alarm, video) onto active sprinkler lines violates NFPA and NEC intent, creates hazards, and can fail an AHJ inspection. Security and communications systems do not normally require enhanced fire resistance unless they are part of the life safety strategy (e. LV and ELV circuits must be segregated or insulated for the highest voltage present. The electrical designer could deem it appropriate to rely on the plasterboard ceiling to provide fire protection to the wiring system in order to prevent premature collapse. However, many influences should be considered such as building size, complexity and evacuation time.
