Electrochemical corrosion

Protection against electro-
static discharge and lightning
For advice on the prevention of hazards due to
electrostatic discharge or lightning, please refer to
relevant publications by national and international
standardization bodies such as the International
Electrotechnical Commission and the American Boat
and Yacht Council.
In particular, the publications IEC 60092-507:2000
Electrical installation in ships Part 507: Pleasure
craft, and ABYC Standards and guidelines H-33 and
E-4 may prove helpful.
Stray current and
shore power corrosion
Stray current corrosion is similar to galvanic corrosion
in the way it acts but differs in the way it is caused.
In galvanic corrosion, it is the potential differences
on the metal that initiates corrosion. As the name
implies, stray current corrosion is caused by stray
currents.
Stray currents can arise as a result of faults in the
boat’s electrical system, such as connections and
splices that are exposed to moisture or bilge water,
equipment that is faulty as a result of damage or
wear, or an electrical system that is incorrectly con-
nected.
Stray current corrosion can also be caused by stray
currents from neighboring boats or equipment for
connecting to a shore based power supply at quays.
