Connecting the Ground Wiring
Figure 3 on page 19 and Figure 4 on page 20 show the location of the grounding screw on the top panel of the
switch. The grounding requirements are:
Use a minimum of #16 AWG solid copper conductor to connect the switch’s grounding
screw to the earth.
Keep the wire length as short as possible.
Continuity from the grounding screw to the earth ground rod must be less than 0.05
ohms.
If a terminal is used, it should be double crimped.
