4.4.6 Wiring Inside Enclosures
Cable sections that run inside protective equipment enclosures are relatively short. As with wiring
external to enclosures, maximum separation between Ethernet cables and Category-1 conductors should
be maintained.
When running cable inside an enclosure, conductors should be routed external to all raceways in the same
enclosure or in a raceway separate from Category-1 conductors. Cable should be routed at least the
distance from the noise source listed in Table 4-10.
Table 4-10 Routing Cable Around Various Noise Sources
Minimum Distance Strength of Noise Source
0.08 meter (3 in.) Category-1 conductors of less than 20 amps
0.15 meter (8 in.) AC power lines of 20 amps or more, up to 100 KVA
0.6 meter (24 in.) AC power lines greater than 100 KVA
4.4.7 Cable Grounding Considerations
For information regarding grounding and bonding requirements for your network, the appropriate local,
regional, and national or international codes should be followed.
