Loading and Supports

First and foremost, a cable tray must act as an effective and durable support for cables. The mechanical performance of cable tray products and accessories are tested against the demanding requirements imposed by the NEMA VE-1 Underwriters Laboratories (UL) and international standard IEC 61537. These standards help ensure cable tray systems safety support cabling in a wide variety of applications.

Safe Working Load (SWL) Calculation:

SWL=Load applied along bracket = Width of bracket (W)/divided by 20 W/20 is maximum acceptable deflection, for example 12"/20 = 0.6" of deflection maximum.

SAFETY
Mesh Structure

In the event of critical overload, a mesh structure becomes like a hammock.

No Walking on Tray

CABLOFIL is only designed to support cables. Under no circumstances should it every be used as a walkway.

Safe Working Loads

While many Legrand/Cablofil supports utilized our Fast Assembly System (FAS) which offers simple one-step locking tabs that require no additional hardware to secure WMCT to supports, our WMCT has been tested to UL, CSA, NEMA, VE-1 and IEC standards. Cablofil wire mesh tray and supports are designed to support any cable load allowed by the NEC when supports are spaced 8' spans. Only the heaviest cables (750 kcmil multiconductor power or larger) may require short spans. For specific loading go to the the interactive table on our website and choose your exact cable for detailed cable capacity and span requirements.

POSITIONING OF THE SPLICE (general scenario applicable to all spans)

To get the best performance from tray, choosing the right couplers is just as important as their positioning. CABLOFIL couplers have been designed and tested to provide high levels of mechanical and electrical performance. To maximise performance, follow the recommendations below:

Optimum Span

100% PERFORMANCE

For best results, place the couplers at 1/5" of the way along the span.

Possible Span

70% PERFORMANCE

If the coupling is at L/2, a coefficient of 0.7 should be applied to the permissible load.

Not Recommended

Never put the support under coupler.

POSITIONING OF THE SUPPORTS

Changes of level and direction:

Put supports in place before there is an deflection of the cable tray route. It is recommended to place supports at the start and end of 90 bends. A support must be positioned in the middle of large-radius bends.
