Chapter Summary Continued
Grounding wires can dissipate electricity from wiring problems and ESD.
Grounding wires route electricity directly to the ground so that it can't damage electronics or hurt people. However, grounding wires don't always have the same potential.
When devices that have two different grounds are attached to each other, voltage can flow between them.
When wiring two buildings, you should use a non-conductive material such as fiber-optic cable.
When there are two different grounding wires between devices or networks, you should use a non-conductive material to connect them.
