What shore power is provided for private yachts in Great Britain, Europe and
the Middle East? What does the shore power receptacle look like? Who are
the major suppliers of this equipment? How are private yachts built for
that market wired? According to N. Calder; yachts built in Great Britain
have 240 VAC /50Hz three wire systems: hot, neutral and safety ground. Also
according to N. Calder; the color coding for these three wire systems has
changed from red to brown for the hot leg, from black to light blue for the
neutral leg and from green to green and yellow for the safety ground leg.
Are there four wire systems analogous to our 50 amp 120/240 VAC systems?

Finally, is there any organization like the American Boat and Yacht Council
with standards for private yachts in the above market?

Thanks in advance.
