Several grounding points on metal cable trays

Summary: The key to grounding metal trays lies in "starting with 2 points, adding one every 20-30 meters, using 2 anti-loose bolts for galvanized trays, and crossing 4mm² copper wire for non-galvanized trays". Strict implementation can ensure personal and equipment safety. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. The metal in cable trays may be used as the EGC as per the limitations. Wire mesh cable trays are widely used in commercial offices, industrial facilities, data centers, and smart building infrastructure because they provide unmatched flexibility, excellent airflow, and fast, adaptable installation. If you take what UL states literally, ANY cut to tray (ladder or wi e) would cause a loss of UL Classification.

How many meters should the ground supports for cable trays be spaced

Typical spacing: Supports every 1. Straight sections: Maximum span should not exceed manufacturer's recommendations. Vertical runs:. Under normal circumstances, the distance between the support arms of the cable tray should be about 1. When installing the cable tray horizontally, its direct plate connection should not be placed at the midpoint of the span or on. Normal Spans: These trays must have support after every 2 or 3 meters. This will involve purchasing additional hangers and wasting more time drilling holes in the ceiling. Ground cable trays at least every 15 m (50 ft) and. The NEC requires that cable trays must be supported by members at an interval specified by the cable tray manufacturer, but not more than 5 feet for horizontal runs to support the weight of the cables and other loads. The NEC has a requirement for ladder-type cable trays.
