Overheating caused by ungrounded cable trays
When there's an excessive amount of cables crowded into a tray or raceway, the heat they produce can't dissipate properly. Here's how it typically unfolds: Heat Generation: Every electrical cable generates some heat. Your original article already highlights the biggest dangers: contact with energized cables, overheating caused by overload, structural collapse, sharp edges, debris. Monitoring Cable Trays is problematic because, by their very nature, cable trays cover long distances and are usually in out-of-the-way locations. The use and installation of cable trays is covered by legally enforceable OSHA regulations in 29 CFR 1910. danage when pulled through penetrations.

Can wiring in a distribution box be bent at right angles
This rule, found throughout multiple NEC articles (for instance, Article 358. 26 for PVC), specifies that the total angle of all bends between any two pull points—such as junction boxes, conduit bodies, or cabinets— must not exceed 360 degrees. The bend radius is the radius of the circular curve made (radius) when you bend a wire back onto itself. 6 (A) applies where conductors do NOT enter or leave the enclosure through the wall opposite their terminals. During installation, cables are bent or flexed in various environmental conditions (Sometimes bent way too far!).
