DC Grounding (Earthing) Locations
NOTE
: For simplicity, all references to ground is also a reference
to earth.
You must connect the DC equipment ground lug to a grounding
point—usually the vessel's chassis—using recommended copper
wire size (if insulated then green insulation with or without one or
more yellow stripes) or larger.
Make sure to tighten the bolt on the ground lug to a torque of 23 in-
lb (2.6 N-m) of force. Apply an anti-corrosion compound to the
copper wire prior to connecting to the ground lug.
For recommended equipment ground cable size, see below.

NOTE
: There are no restrictions on length for the equipment
ground cable but try to make it as short as practical to a secure
chassis connection. In general, the equipment ground cable size
must not be smaller than one gauge than the supply cable.
