BS EN 1648-2:2018 specifies safety, health and functional requirements for 12 V direct current (DC) extra low voltage (ELV) electrical installations for habitation aspects of motor caravans.It applies only to installations which are electrically connected with the electrical installation of the base vehicle or which can be electrically connected with it by means of change-over devices.This European Standard also specifies the ELV output requirements of low voltage (LV) equipment that may be used to provide an ELV supply but it does not specify safety, technical and functional requirements for LV appliances and installations. Requirements for LV installations are specified in HD 60364-7-721.Cross References:EN 60529ISO 6722 (all parts)ISO 8820-1ISO 7010HD 21ISO 6722HD 22EN 1646-1EN 50525 (all parts)ISO 8820-3ISO 8820-4EN 60898-2IEC 60898-2EN 13878IEC 60529EN 13878:2003ECEN 1645-1EN 721IEC 60364-7-721EN 1647EN 1646-1HD 60364-7-721EN 50102EN 1649HD 60364-4-43EN 1648-1IEC 60364-4-43All current amendments available at time of purchase are included with the purchase of this document.
