The particular requirements specified in this part of IEC 60364 apply 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: - the removal of the requirements for the electrical installation in pleasure craft as these are now covered by IEC 60092-507; - the requirements of this part have been aligned with those in other parts of IEC 60364.
