Important note: The theoretical number of cables that can be supported on a 450 × 54 mm tray (6 mm lateral wires) equates to the number of cables that equate to the 100 kg/m load which results in a 7·5 mm deflection on a 1·5 m span. This does not take into account the limit of the physical dimensions of the tray, just refers to the load carrying capability. It should be used as a guide only and is not contractual in any way.#
