It is recommended cable tray sections be secured to the support or mounting brackets at random intervals using a 4 inch center support (CM54-04), or a standard cable clamp. All nuts must be tightened securely using a 1/2″ wrench or similar tool to insure good equipment ground conductivity.Ħ. The heads of all carriage bolts must be located inside of the cable trays, drops or junctions to prevent damage to the cable insulation.ĥ. All interconnection points must be secured with a carriage head bolt and flange nut oriented.Ĥ. Butt the sections together and secure using a CM68 carriage bolt and CM67 flange nut at each connection point.ģ. Align each adjacent cable tray and/or junctions together so the galvanized portion of each connecting loop overlaps the outside surface of the galvanized interconnect point of each tray section side wall. Inspect all connection loops and interconnection points of each cable tray, elevation change and junction to insure the contact surfaces (both top and bottom) are free from paint, dirt, or other material that may hinder conductivity or proper connectivityĢ.
The hanging or mounting hardware should be secured to the building structure first, spaced at 5 ft.intervals.ĬONNECTING STRAIGHT AND JUNCTION SECTIONSġ. It is recommended that the installer starts at a junction location and attach tray sections from that point out.
