AS 61534.1:2020 Powertrack systems Part 1: General requirements (IEC 61 534-1:2011+AMD1:2014 CSV (ED.2.1) MOD).
1.1 This part of IEC 61534 specifies general requirements and tests for powertrack (PT) systems with a rated voltage not exceeding 277 V a.c. single phase, or 480 V a.c. two or three phase 50 Hz or 60 Hz with a rated current not exceeding 63 A. These systems are used for distributing electricity in household, commercial and industrial premises.
1.2 Powertrack systems, according to this standard, are intended for use under the following conditions:
— an ambient temperature in the range —5 °C to + 40 °C, the average value over a 24 h period not exceeding 35 °C;
— a situation not subject to a source of heat likely to raise temperatures above the limits specified above;
— an altitude not exceeding 2000 m above sea level;
— an atmosphere not subject to excessive pollution by smoke, chemical fumes, prolonged periods of high humidity or other abnormal conditions.
In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for instance, where explosions are liable to occur, special constructions may be necessary.
This standard does not apply to
— cable trunking systems and cable ducting systems covered by IEC 61084 [8] 1;
— busbar trunking systems covered by IEC 60439-2 [5];
— electrical supply track systems for luminaires covered by IEC 60570 [6].

3.2
system component
part specifically designed for the PT system which may or may not incorporate an accessory
3.3
powertrack
system component which is a generally linear assembly of spaced and supported busbars providing electrical connection of accessories
NOTE A powertrack may also provide mechanical support for accessories.
3.4
busbar
main current carrying conductor(s) to which for example one or more tap-off units, accessories or electrical system components may be connected
3.5
accessory
electrical device complying with its own standard and associated with or incorporated in the PT system
3.6
rewireable accessory
accessory so constructed that a cable can be fitted or replaced using a tool
3.7
non-rewirable system component
system component so constructed that it forms a complete unit with the cable after connection and assembly by the manufacturer of the system component.AS 61534.1 pdf download.
