Abstract
Add the following paragraph: This part applies to the busbar trunking system (BTS) and auxiliary facilities for power supply and distribution in residential areas, commercial areas, public places, agricultural and industrial buildings. This part also applies to busbar trunking systems equipped with communication and/or control systems, or busbar systems that provide lighting through tap-changers, but does not apply to power supply line systems that comply with GB/T 13961—2003. The busbar trunking systems described in this part (including various length units and bending units) are considered type-tested complete equipment (TTA) if they have been tested in accordance with Chapter 8 of this part. Tap-changers can be considered partial type-tested complete equipment (PTTA).
