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?

Most shore supplies in UK/Europe are nominally 230V 16A. In the UK the
nominal 230V is really 240V, in parts of continental Europe more likely
220V.

This is a single phase three wire supply:
live - brown
neutral - blue
earth(ground) - green with yellow

I have a metal narrowboat and use a galvanic isolator between my boat
earth and the earth in the supply lead to prevent electrolysis. Some
people use a (hefty) 240/240V isolation transformer.

There are pictures of plugs and sockets at

Maplin part # KC79L is the plug. See the Maplin site for specs.
Lots of other outlets carry the plugs.

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


Thanks in advance.
