BS EN 1648-1:2018 specifies safety, health and functional requirements for 12 V direct current (DC) extra low voltage (ELV) electrical installations for habitation aspects of caravans. It covers the design and integration of the caravan system with the towing vehicle system.It does not apply to commercial trailers; nor does it include requirements for ELV road lighting and signalling lamps and their installations, except for safety requirements for the routing of cables in LPG storage compartments.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:IEC 60364-4-43HD 60364-4-43IEC 60529ISO 6722 (all parts)ISO 8820-4ISO 8820-3IEC 60898-2EN 60529EN 50525 (all parts)ISO 7010EN 13878EN 60898-2ISO 11446-1:2012EN 1648-2EN 1647HD 60364-7-721EN 1645-1ISO 8820-1EN 1646-1EN 50102EN 722-1EN 1649EN 721All current amendments available at time of purchase are included with the purchase of this document.
