Cable trays are often treated as an afterthought, which leads to issues like insufficient space or improper routing of cables. Solution: Assess the cable load, tray size, and future expansion needs during the design phase. Properly cutting a cable tray ensures the integrity of the system, safety, and compliance with electrical codes. Inadequate cuts can lead to. Cable sag results from incorrect spacing of cable tray supports or from employing the incorrect tray type that is, light-duty perforated trays in high-load applications. Complicating the problem are overloaded trays and large unsupported spans. Under. en completely installed, without damage either to conductors or structural system use maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. For some reason, when inserted with "trim/extend to corner", it does not cut properly one of the pieces of tray, but adds strange another fitting.
