Short answer: port and marine electrical accessories should be selected by salt spray exposure, corrosion class, IP rating, material, grounding continuity and outdoor UV resistance.
| Cable entries | Use stainless steel, nickel plated brass or approved glands with correct cable range and IP rating. |
|---|---|
| Grounding and bonding | Use tinned copper, stainless steel, copper bonded conductors, braids and corrosion-resistant clamps. |
| Routing support | Use coated or stainless tray, conduit, supports, ties and fasteners according to salt exposure. |
| Surge and lightning | Use SPDs, arresters, rods, earth bars and bonding network for exposed port equipment. |
Marine electrical accessories should not use ordinary indoor materials. Salt exposure quickly changes the correct material and surface treatment.
