Electrical Installations

An incorrectly-carried-out electrical installation may
generate leakage current from the electrical system.
Leakage current can in turn render galvanic protection
inadequate in respect of propellers, propeller shafts,
rudder posts, the keel etc., and may cause damage
through electrochemical corrosion.
Work on the low voltage circuits in the boats should be
done by a person with electrical training or knowledge.
Installation or work on land current equipment must
only be done by a competent electrician, in accordance
with local regulations for mains electricity.
The following must always be heeded:
1 If shore power is connected it must always be

WARNING!
ground protected ashore, never in the boat.
Furthermore, the shore power installation should be
equipped with a ground fault interrupter.
The shore power installation (transformer, inverter,
battery charger etc.) must be designed for marine
use where the high-tension side is galvanically
separated from the low-tension side.
that there is no risk of exposure to chafing, damp or
bilge water.
instruments, rudder, boarding ladders or other
equipment where separate cables for ground
protection are present, must be clustered to a
common ground connection (B) that is not
connected to the engine or transmission.
IMPORTANT:
Never use the engine or transmission as earth
planes.
The S-drive is insulated electrically (A) from the
engine and may never be used as the ground or be
connected electrically to other equipment such as
radios, navigation equipment, rudder, and boarding
ladders.
