Dryer Master DM510 Installation Manual
When ground connections are made at various points along a ground conductor the effect is much
different. Figure 23 - Effects of surge current in a conventional ground system illustrates that current
flow in the ground wiring results in increasing differences in ground potential in each piece of
equipment connected downstream from the surge event. The result can be current flow between
devices as a result of a difference in ground potential.
