About this detail

A 1/4" thick by 4" wide by 20" long copper ground bar is mounted to the wall using specialized brackets and insulators. Multiple bare copper conductors terminate at the bus bar via two-hole compression ground lugs, routing to the main electrical service ground, structural footing, building steel, water pipe, MDF room ground bar, and low voltage normal power electrical room ground ring. All grounding connectors require double lug, double compression terminations on both ends. The contractor is responsible for providing a complete working installation with miscellaneous appurtenances and plenum-rated sheathing where required.
