A necessary space must be devoted to workers on the cable trays under the false floor (cable tray modifications, pulling and crimping cables) to avoid walking on it.
Vertical stacking of redundant cable trays should be avoided, if at all possible, but where such arrangement is employed, minimum vertical spacing should be five feet between the two
There are various ways of including strain relief sections, but the preferred method is to offset the cable by at least 2 cable diameters for each strain relief section.
