Ground Lug
 Once you have installed the unit, run a ground wire between the ground lug
and a known good earth ground. You route the ground wire through one of
the conduit fittings.
 Use stranded copper wire to earth ground and keep the length as short as
possible.
 Clamp or braze the ground wire to the ground bed conductor (typically a
stranded copper AWG 0000 cable installed vertically or horizontally).
 Run the ground wire so that any routing bend in the cable has a minimum
radius of 30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above
ground.
 For more information on grounding or if your installation uses cathodic
protection, refer to Site Considerations for Equipment Installation, Grounding,
and Wiring (D301452X012).
