Separation from Sources of Interference
Unshielded data cables should not be installed near sources of electromagnetism.
EIA/TIA-569, the cabling pathways standard for data cables, specifies these distances for structured data cabling systems:
Minimum Separation Distance from Power Source at 480V or less |
| Condition |
<2kVA |
2-5kVA |
>5kVA |
| Unshielded power lines or electrical equipment in proximity to open or non-metal pathways |
5 in. |
12 in. |
24 in. |
| Unshielded power lines or electrical equipment in proximity to grounded metal conduit pathway |
2.5 in. |
6 in. |
12 in. |
| Power lines enclosed in a grounded metal conduit or equivalent shielding (in proximity to a grounded metal conduit pathway) |
