Earthing the Armour of a SWA ethernet cable on a gland connection

Asked 2 weeks in Wired Network Infrastructure by Adam | 1 Answer

I'm looking to run a length of SWA CAT 6 cable externally between house and garage. It won't be run alongside any power cables, and will only ever get within a few feet of any. I plan to make off a gland at either end into wall-mounted plastic junction boxes and connect to patch cables.

Do I still need to earth the SWA at one or both ends? And if so, how would I do that considering that usually with electrical cable, the gland would be earthed to that via an earthing nut, but with ethernet cable there is nothing to earth to?

Hi Adam

It is not essential to earth the steel wire armour on a data cable as there will never be a high voltage on the cable. If the cable is shielded you should connect the drain wire and foil shield to a shielded RJ45 plug and use a shielded socket and shielded infrastructure to ensure that the shield remains continuous and gets grounded at the data cabinet.
