Grounding

Grounding runs excess electrical current to ground. Grounding is needed

grounding conductors. See Adding Busbars.

Step 2 Select the Grounding category in the List View.

Step 3 Click the Busbars radio button and then the Add button in the List View

area.

Step 4 The Location box in the Detail View is populated with the space where

the busbar will be set up.

Step 6 Select the busbar type from the drop-down list in the Busbar Type field.

Step 7 Click Save.

TMGB (Telecommunications Main Ground Busbar) is the main busbar that goes

directly to the earth ground. The Grounding Conductor ID is the main conductor that

connects the TMGB to the ground. The TGB (Telecommunications Ground Busbar)

is a busbar that will connect to a conductor. Select it from the Busbar Type drop-

down list. No other fields appear on the tab when TGB is selected.
