CLC/TS 50502:2008

Railway applications - Rolling stock - Electric equipment in trolley buses - Safety requirements and connection systems

This Technical Specification applies to electrical systems on board trolley buses, as defined in 1.3.1, fed with a nominal line voltage (Un) between 600 V d.c. and 750 V d.c. This Technical Specification defines the requirements and constructional hints, especially to avoid danger of electrical kind to the public and to the personnel. CLC/TS 50502 is normative only for vehicles ordered and designed after publication of the same. This Technical Specification covers vehicles intended for public transport of persons. It refers mainly to earthed networks, but reference is made also to galvanically insulated networks. Annexes B and C are related to the connection systems. The detailed scope of these annexes is given in Annex B.
