1 Scope
1.1 This part of IEC 61 534 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 61 084 [8] 1 ; – busbar trunking systems covered by IEC 60439-2 [5]; – electrical supply track systems for luminaires covered by IEC 60570 [6].
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 powertrack system PT system assembly of system components including a powertrack by which accessories may be connected to an electrical supply at one or more points (pre-determined or otherwise) along the powertrack 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 3.8 connector device which provides the electrical connection and possibly the mechanical connection of powertracks 3.9 supply connector device enabling the supply wiring to be connected to the powertrack 3.1 0 live parts conductor or conductive part intended to be energized in normal operation, including a neutral conductor, but by convention not a PEN conductor [IEC 60050-1 95:1 998, 1 95-02-1 9, modified] [2] 3.1 1 rated voltage, rated current value assigned to a PT system by the manufacturer and to which operation and performance characteristics are referred 3.1 2 clamping unit part(s) of a terminal necessary for the mechanical clamping and the electrical connection of the conductor(s) including the parts which are necessary to ensure the correct contact pressure 3.1 3 termination part of a PT system to which a conductor(s) is attached providing a non-reusable connection 3.1 4 terminal part of the PT system composed of one or more clamping unit(s) to which a conductor(s) is attached providing a reusable connection 3.1 5 insulation piercing connecting device IPCD connecting device for the connection and possible disconnection of one conductor or the interconnection of two or more conductors, the connection being made by piercing, boring through, cutting through, removing, displacing or making ineffective in some other manner the insulation of the conductor(s) without previous stripping NOTE The removal of the sheath of the cable, if necessary, is not considered as a previous stripping. 3.1 6 flat quick-connect termination electrical connection consisting of a male tab and a female connector which can be inserted and withdrawn with or without the use of a tool 3.1 7 plug accessory intended for connection to a flexible cable intended for frequent manual engagement with a socket outlet 3.1 8 socket-outlet accessory having a set of contacts designed to engage with the pins of a corresponding plug and which may have terminals or terminations for the connection of conductors
