Route piping over or under cable trays? | Eng-Tips
Typically the cables inside the tray are a higher priority to be able to access. Ergo, tray under.
FactSheet
Overloading cable trays can lead to a breakdown of the tray, its connecting points, and/or supports, causing hazards to persons underneath the cable tray and even leading to possible electric shock
Cable Tray Fill Rules (NEC 392)
Multiconductor cables (Type MC, TC, AC, or any cable with two or more insulated conductors plus a jacket) follow the fill rules in NEC 392.22 (A). The rules are based on the cross
Install cable tray under raised flooring | Cabling Installation
If the cable tray is installed on the floor slab, electrical cables can be run across the top of it, possibly leading to electromagnetic interference from the high-voltage cables.
Explaining NEC Article 392 on Cable Trays
Cables and conductors must be secured to the cable tray at intervals according to installation instructions. For non-horizontal runs, cables should be fastened securely to transverse
Conductors/Cables passing though a cable tray (without entering the
I don''t recall that it is prohibited so that suggests it is allowed. It is something that is done on a regular basis where two cable trays intersect at right angles. There is a pass through of those
