Is the cable tray elevation the bottom or the top of the cable tray
Top of Cable Tray The elevations refer to the top of the cable tray. The cable tray will extend below these elevations. Dust buildup is minimal compared to other types of cable tray, such as ventilated trough or solid bottom. An elevation benchmark (preferably set by the general contractor) can be transferred via laser level or transit to convenient points along the length of the tray run. Once the lengths and quantities of the hangers are. Include scaled cable tray layout and relationships between components and adjacent structural, electrical, and mechanical elements. Show the following: Vertical and horizontal offsets and transitions. During installation, the necessary safety. -
