Does the cable tray support need to be pulled out

No, cable tray supports should not be pulled out; modifications must use proper fittings to maintain structural integrity and code compliance.Key ConsiderationsCable trays are designed as rigid support systems for electrical cables, not as enclosures or conduits. They provide structural support, proper spacing, and ventilation for cables, and are governed by NEC Article 392 and UL standards . Pulling out or cutting supports, such as rungs in ladder-type trays, can compromise the tray's strength, grounding path, and safety compliance .Proper Methods for AdjustmentsUse approved fittings: To change direction, elevation, or create bends, installers should use elbows, junctions, or corner strengthening bars rather than removing parts of the tray .Maintain grounding and structural integrity: Modifying trays by cutting or removing supports can void UL certification and lead to failed inspections .Flexible tray options: Some systems, like hand-bendable steel trays, allow directional changes without cutting, preserving compliance and safety .Installation Best PracticesEnsure supports are spaced according to manufacturer and code requirements to handle the weight of cables .Plan cable pulls to minimize bends and tension, using rollers or sheaves to protect cable jackets .Ladder trays provide ventilation and anchor points, while solid-bottom trays are used where EMI protection or concealment is needed .SummaryCable tray supports should remain intact. Any adjustments to the tray path should be made using approved fittings or flexible tray systems to ensure compliance with NEC and UL standards, maintain structural integrity, and protect the cables. Pulling out supports is not recommended and can result in safety hazards and failed inspections .
