How to connect all ground cable?


Set the priority for grounding on the tower, as follows;

1) Connect to bus bar installed on tower by using 2 holes cable lug.

2) Connect to the main ground cable from tower to ground



3) Connect to lightning protection ground cable

4) Connect between the tower segments connection. (If any additional ground cable, can be grounded to this cable by using C-clamps as shown below)



5) Run a new main ground cable from equipment to ground level and Connect the equipment on the tower to the new main ground cable with C-clamps.
