A cable tray fitting which is suitable for joining cable trays in three directions at 90 degree intervals in the same plane. A generic guideline developed by the cable tray institute indicates that cable trays should not be filled in excess of 40 50 of the inside area of the tray or of the tray s maximum weight based on the cable tray specifications. One or more spans iec 61537 7 3i for installations with more than one span it is important to notice that the loading capacity is not the same form one end to the other. The 2014 nec requires the labels to be visible after installation and spaced no further than 10 ft.

See the actual nec text at nfpa org for the complete code section. The length between support positions will change depending on the cable design size materials and weight. To join two components together clamp or fix to walls ceilings or other supports covers and cable retainers associated supports bespoke supports for cable tray and cable ladder other than bs 6946 channel. Longer spans mean fewer supports which translates to lower installed costs.

Cable load working load the cable load or the working load is the total weight of the cables to be placed in the tray. For example an mdpe sheathed cable will be stiffer and therefor require a greater distance between supports than the same lsoh cable to achieve the same 2 deflection sag. Support load calculation per iec 61537. Mushroom headed steel roofing bolts and nuts shall be used for the installation and coupling of trays.

Evenly distributed load 2 x point load support distance. 6 cable ladder and cable tray systems including channel support systems and other associated supports definitions and abbreviations accessory component used for a supplementary function e g. Metallic cable tray system. The nema classes are based on cable loads of 50 75 and 100 per lineal foot.

The label ensures that the service entrance conductors can be traced throughout the cable tray. This classification is based on the working load the total weight of the cables and the support span the distance between supports. Cable trays shall be supported by mild steel galvanized brackets at regular intervals of 1 2mm maximum and at 255mm from bends and tees. The cable tray institute cti was founded in 1991 to support the cable tray industry by engaging in research development education and the dissemination of information designed to promote enhance and increase the visibility of the industry.
