Grounding the Switch
Follow the grounding procedure instructions and observe these warnings:
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
Statement 1024
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Statement 1046
Caution To make sure that the equipment is reliably connected to earth ground, follow the grounding
procedure instructions, and use a UL-listed lug suitable for number-6 AWG wire and two number-10-32
ground-lug screws.
Follow these steps to install a dual-ground lug on the switch. Make sure to follow any grounding
requirements at your site.
Step 1 Locate the dual-hole lug that ships with the switch.
Step 2 If your ground wire is insulated, use a wire stripping tool to strip the 6 AWG ground wire to 0.875 inch
(12.7 mm) ± 0.02 inch (0.5 mm).

Step 3
Slide the open end of the ground lug over the exposed area of the wire.
Step 4 Crimp the ground lug to the wire (see Figure 3-9).
