6 Definitions of Cable Bundle per Codes

TIA-TSB-184-A:

"A group of cables that are tied together or in contact with one another in a closely packed configuration for at least 1 m."

ANSI/TIA-569-D-2:

"A group of cables that are tied together or in contact with one another in a closely packed configuration for at least 1 m."

ANSI/BICSI N2-17:

"A group of cables that are tied together or in contact with one another in a closely packed configuration for at least 600 mm (24 in)."

2020 NEC 725.2 Second Draft:

"A group of cables that are tied together or in contact with one another in a closely packed configuration for at least 1.0 m (40 in)."

ISO/IEC TS 29125:

"Several cables tied together or in contact with one another in a parallel configuration for at least 1 m, with the cross-section profile of the arrangement basically circular."

ISO/IEC 14763-2:

"Multiple cables maintained in close proximity, generally by fasteners (e.g. cable ties)."
