Installation
Ground lug
DANGER
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
30.5 cm (12 inches) below ground and 20.4 cm (8 inches) above ground.
For more information on grounding or if your installation uses cathodic protection,
