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. Electricians should always. If a tray is overloaded, corroded, poorly supported, or contains live cables, it can create severe risks for workers and equipment. Your original article already highlights the biggest dangers: contact with energized cables, overheating caused by overload, structural collapse, sharp edges, debris. Cable overheating is a critical issue in electrical systems, leading to potential hazards such as fires, equipment damage, and system failures. If your cable tray system is buckling under the pressure, figuratively or literally, it's time to act.
