This part applies to busbar trunking systems (BTS) and their accessories for feeding and distributing electrical power in residential, retail, public, agricultural and industrial premises. It also applies to busbar trunking systems which are designed to incorporate communication and/or control systems or intended to supply luminaires through tap-off units but does not apply to supply track systems in accordance with GB/T 13961-2003. The busbar trunking systems (including variations in length and angles of bends) considered in this part are type-tested ASSEMBLIES (TTA) when tested in accordance with Chapter 8 of this part. Tap-off units may be partially type-tested assemblies (PTTA).
