On board there is an adequate grounding dispersion system fitted with a porous plate which constitutes the “means” of grounding the generator PE conductor, to which all the grounds of the alternating current systems are connected as well as all the negatives of the direct current systems.
If the yacht is out of the water, position the ground bar near the platform panel in the DRY DOCK position.
