About this detail

Each section of tier one, two, or three cable trays is bonded together at the splice point using a number six American Wire Gauge copper jacketed bonding jumper. The fifteen-inch long jumper features two crimped tinned lug connectors with three-eighths inch diameter openings, secured with hex head bolt assemblies including nuts and lock washers into field-drilled mounting holes. A number two-slash-zero American Wire Gauge grounding conductor routed in a three-quarter inch conduit connects the tray to the nearest ground bar every one hundred feet.
