Electrical installations
Leakage current from the electrical system can be
caused by incorrect installation of electrical equip-
ment. Leakage current can knock out the galvanic
protection of components such as the drive, propel-
ler, propeller shaft, rudder stock and keel and cause
damage by electrolytic corrosion.
IMPORTANT! Work on the boat’s low tension
circuit should only be carried out by qualified or
experienced persons. Installation or work on
the shore power equipment must only be car-
ried out by electricians authorized to work with
high-voltage installations.
The following should always be observed:
1. If shore power is connected, the protector ground
should be ashore, never in the boat. Shore power
should always have a ground fault circuit break-
er.
Shore power units (transformer, rectifier, battery
chargers etc.) must be intended for marine us-
age and the high tension circuit must be gal-
vanically separated from the low tension cir-
cuit.
2. Route and clamp electric cables so that they will
not be exposed to rubbing, damp or bilge water in
the keelson.
3. Engine or drive/reverse gear must never be used
as a ground point.
IMPORTANT! The engine or drive/reverse
gear must never be used as a ground or be
electrically connected to other equipment
such as the radio, navigational equipment,
the rudder, bathing steps etc.
Protective grounds for the radio, navigational
equipment, rudder, bathing steps or other equip-
ment with separate ground leads must be con-
nected to a common ground terminal.
4. There must be a main switch connected to the
starter battery positive (+) terminal. The main
switch should cut off power to all power consum-
ing equipment and should be switched off when
the boat is not in use.
