Title Mini-couplers for the interconnection of electrical mains supplied equipment in road vehicles
Project Number 3389
Abstract/Scope This standard specifies general safety requirements for mini-couplers with a rated current of 16 A and a rated voltage of 250 V a.c. single phase, applies for the interconnection of mains supplied equipment in road vehicles e.g. to supply electrical heaters, battery chargers and cab heaters. This standard may also be used for mini-couplers for other similar applications. The standard does not apply to devices used in flexible supply cables for the connection of household electrical appliances and the like to their supply. The introduction of requirements for mini-couplers for 440 V three phase is under consideration. It should borne in mind that aspects of product liability will have to be considered in conjunction with the use of mini-couplers
