In-building cable routing

Introductory The EMC rules with regard to in-building cable routing (inside and outside
remarks
cabinets) require certain clearances to be maintained between individual line
groups. Table 5-1 shows the general rules with regard to spacing as they
apply to cable selection.
How to read the
If you want to know how two cables of different types should be routed,

1. Find the first cable type in column 1 (cables for ...).
2. Find the second cable type in the corresponding section of column 2 (and
3. Read off the applicable guidelines in column 3 (route ...).
