All metallic cable coverings (armour, metallic sheathing and other protection) must be electrically connected to the vessel's
hull at both ends except in the case of final sub-circuits where they should be connected at the supply end only.
Grounding connections should be made using a conductor which has a cross-sectional area appropriate for the current rating
of the cable, or with a metal clamp which grips the metallic covering of the cable and is bonded to the hull of the vessel.
These cable coverings may also be grounded by means of glands specially intended for this purpose and designed to ensure a
good ground connection. The glands used must be firmly attached to, and in good electrical contact with, a metal structure
grounded in accordance with these recommendations.
Electrical continuity must be ensured along the entire length of all cable coverings, particularly at joints and splices.
In no case should the shielding of cables be used as the only means of grounding cables or units.
Metallic casings, pipes and conduits must be grounded, and when fitted with joints these must be mechanically and electrically
grounded locally.
