From past experience I have found that even when using a permanent marker the ink still gets rubbed off or becomes illegible due to handling or dirt getting on the cable sheath. An added advantage of using coloured tape is that the cables can be identified from across the room.
The scheme chosen for this installation uses 4 bands of tape using 4 colours. This gives 4x4x4x4 = 256 possible combinations to mark the cables. To increase the capacity of the system either add an extra colour or another band of tape.
4 bands of 4 colours gives 256 combinations
4 bands of 5 colours gives 625 combinations
5 bands of 4 colours gives 1024 combinations
5 bands of 5 colours gives 3125 combinations
If your wiring scheme needs more than that, I would love to see it. Colour Sequence is reading towards the cut end of the cable e.g. RRRY is RED RED RED YELLOW with the Yellow band nearest the end of the cable.
