Wire and Cable Categories
The table below indicates the best zone for running cables and wires.
The table also shows how the use of ferrite sleeves and shielded cable
can reduce the noise effects of dirty and very-dirty wires and cables.
Note: Some items have two entries (one shielded and one not
shielded).
