| 8.6.6 | Safety ground connections
An example of a wiring fault, that could occur in a network device, is an accidental connection between the hot wire and the chassis. If such a fault were to occur, the safety ground wire connected to the device would serve as a low resistance path to the earth ground. When properly installed, the low resistance path, provided by the safety ground wire, would offer sufficiently low resistance, and sufficient current-carrying capacity, as to prevent the build up of hazardously high voltages. Also, because the circuit would then directly link the hot connection to ground, any time electrical current passed via this path into the ground, it would cause protective devices such as circuit breakers to activate. By interrupting the circuit to the transformer, circuit breakers stop the flow of electrons, thus reducing the risk of electrocution.
