Lightning surge arrestor and bracket (USA)
Before you connect the ground lead to the lightning surge arrestor, attach it to an approved ground.
Tip - The recommended wire gauge is 6 AWG. Connect the ground lead to the building ground. Do not connect to a ground rod or series of ground rods. If you cannot connect the ground lead to the building ground, connect it to the steel frame of the building. The connection should be no more than 6 to 1 0ft.
You can also connect the ground lead to the 120 V ac conduit (which is connected to the building ground), but this is not a preferred installation.
