Note 1: In some equipment sites, depending on the grounding topology
and the size of the building, the floor ground bar (FGB) and the building
principal ground (BPG) may be the same busbar.
Note 2: In some equipment sites, depending on the grounding topology,
the power plant BRR ground bar may be determined as being the SPG.
Then, the BRR lead is usually run to the FGB.
Cabling and connecting the ground leads involves:
1 “Connecting the power plant frame ground (or safety ground) leads” on
page 111
2 “Installing safety ground/protective earth wiring” on page 123
