8 Railboss Railroad Track Scale
4.0 Grounding
Rice Lake Weighing Systems strongly recommends installation of the RailBoss grounding system to protect the
RailBoss Railroad Track Scale from surges. Rail track scales of all types can be exposed to surges or lightning that
may hit the rail at even very long distances from the scale. It is recommended that scale sections be isolated from
the rail track on both ends of each section. Eight-foot ground rods should be driven between the rails, and a copper
wire connected to the rail on each side with a 10-gauge copper wire. Rail joint bar isolators (included) should also
be installed at each end of RailBoss sections.

Ground rod placement can vary depending on ground hardness; however, 8 ' ground rods should be installed near
the center of the track. See Figure 4-1 and 4-2 for recommended ground rod locations.
