IEC 60364-7-709:2007+A1:2012 applies only to circuits intended to supply pleasure craft or houseboats in marinas and similar locations. The particular requirements do not apply to the supply of house boats if they are directly supplied from the public network. The particular requirements do not apply to the internal electrical installations of pleasure craft or house boats. For the remainder of the electrical installation of marinas and similar locations the general requirements of IEC 60364 together with the relevant particular requirements of IEC 60364-7 apply. This second edition of IEC 60364-7-709 cancels and replaces the first edition, published in 1994. It constitutes a technical revision. The major changes with regard to the previous edition concern are the removal of the requirements for the electrical installation in pleasure craft (these are now covered by IEC 60092-507) and the alignment of the requirements with those in other parts of IEC 60364. This consolidated version consists of the second edition (2007) and its amendment 1 (2012). Therefore, no need to order amendment in addition to this publication.
