32、trunking systems (busways) 1 Scope NOTE 1 Throughout this part, the abbreviation BTS is used for a busbar trunking system. Where reference to Part 1 is made, the term ASSEMBLY therefore reads as “BTS”. This part of IEC 61439 lays down the definitions and states the service conditions, construction r

33、equirements, technical characteristics and verification requirements for low voltage BTS (see 3.101) as follows: BTS for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; BTS intended for use in connection with the generation, transmission, distribution and

34、conversion of electric energy, and for the control of electric energy consuming equipment; BTS designed for use under special service conditions, for example in ships, in rail vehicles, and for domestic applications (operated by unskilled persons), provided that the relevant specific requirements ar

35、e complied with; NOTE 2 Supplementary requirements for BTS in ships are covered by IEC 60092-302. BTS designed for electrical equipment of machines. Supplementary requirements for BTS forming part of a machine are covered by the IEC 60204 series. This standard applies to all BTS whether they are des

36、igned, manufactured and verified on a one-off basis or fully standardized and manufactured in quantity. The manufacture and/or assembly may be carried out by a manufacturer other than the original manufacturer (see 3.10.1 and 3.10.2 of Part 1). This standard does not apply to individual devices and

37、self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant product standard. This standard does not apply to the specific types of ASSEMBLIES covered by other parts of the IEC 61439 series, to supply track systems in accordance wi

38、th IEC 60570, to cable trunking and ducting systems in accordance with the IEC 61084 series, nor to power track systems in accordance with the IEC 61534 series. 2 Normative references This clause of Part 1 is applicable except as follows.
