This European Standard specifies requirements relating to devices for the supply of electrical power (three-phase AC - 400 V, with a frequency of 50 Hz and with a current of at least 250 A) to vessels in port. Annex A to this European Standard stipulates general and safety-technical requirements relating to the shore-based section of the electrical shore connection. Annex B to this European Standard stipulates general and safety-technical requirements relating to the connecting cables and to the on-board section of the electrical shore connection. The requirements according to the HD 60364 and HD 384 series of standards generally apply to shore-based low-voltage equipment. The requirements of Annex A of this European Standard complement the requirements contained in HD 60364/HD 384 Parts 1 to 6.
