To make the chassis ground connection:
Step 1. Run a single length of #18 AWG wire (minimum) from the ground point (building
ground or equipment ground bus) to the chassis ground stud.
Step 2. Using a wire-stripping tool, strip the insulation from the wire according to local
safety codes and crimp the ring lug to the wire (Figure 14).
Step 3. Remove the Keps nut and star washer from the ground stud on the mounting
bracket.
