It's good practice to locate low voltage cables away from the mains cables.
Nothing to do with any electricution risk, though it does stop any possible incidents where mains voltage could be introduced onto low voltage cabling when accidental damage etc occurs.

If you're determined to earth the shielding, you should only do it at one end to prevent earth loops. It is more important not to run signal cables alongside mains cables to avoid electrocuting telephone engineers. Signal cables should never share conduits or junction boxes with power cables.

I've already opened the box so I can't return the shielded cable. I might as well just use it then.

My ethernet cable shares the same conduits because it's the most practical way to run the cable up to the first floor. It's a pain to install a new conduit. So I should run my cable in a seperate conduit?

Am just curious how can sharing the same conduit introduce electrocution risk? The cable has a plastic covering. Also I thought you can't use thin cable on high voltage circuits. Wouldn't the Ethernet cable just melt away?

Special considerations of electrical interference. both electromagnetic and electrostatic, may apply to telecommunication circuits, data transfer circuits and the like when sharing ducts with mains circuits...


when im running alarm cables or any cables to do with any access control gear,then there always seperate from ducts containing 240...for the above reasons...........not really to do with risk of any 1 getting a 240 dink...
