Are they cable schedules?

For a large installation normally just a list:

Cable No. 100 101
Type SWA SWA
Cores 27 12
Source Panel 1 Panel 2
Destination Panel 2 Panel 3
Length M 25 15

Each cable will have a list

Core 1 2
Ref K2/B6/12 K2/B6/13
Term B6/12 B6/13

Make sure you get your self ferule applicators for the core numbering otherwise you’ll have no finger ends left.
