Grounding value of cable tray
Where cable tray systems contain only signal and communication circuits that operate at low energy levels, power grounding per NEC Section 318-7 is not appropriate, but cable tray grounding for lightning protection, noise, and electromagnetic interference is necessary. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. These definitions are NEC terminology and apply to power system grounding. 8, 11, and 12, and the. Grounding in cable trays is an important practice to increase electrical safety and prevent hazards in case of faults.

Since the jaws of the bolt cutter drags a layer of zinc across the cut end and forms a protective layer. To remove the lip we can use a small hand grinder (B) or a file. Table 2 of NEC provides the minimum radius of conduit bends. Is there some similar table or other reference available for the minimum radius of cable tray bends? For example, if we have to make a field bend for a 12” (300mm) metallic ladder tray using straight sections of this tray, then how much. Most cable trays are made from metals like steel or aluminum because of their strength and resistance to corrosion.
