Steel Conduit

[h901]

Hi

Just got a quick question. I install CCTV systems and want to start using steel conduit instead of PVC.
Do I need to ground the conduit if it will only have CAT6 network cable inside.

Thanks

If its an exposed conductive part it needs earthing. if its an extraneous conductive part it needs bonding. If its neither it doesn't need earthing nor bonding.

Could be classed as extraneous conductive part?
Paahh, took too long to type!

Thanks for the replies

I'm not too familiar with the terminologies, could you explain what they mean in layman terms.

Pull up a chair!

And have look at these two vids:

Done this cos' I can't type as fast as Lee

exposed conductive part- conductive part of equipment which can be touched and which is not normally live, but which can become live under fault conditions.

extraneous conductive part- a conductive part liable to introduce a potential, generally earth potential, and not forming part of the electrical installation.

Thanks guys

Think he's busy watching the vids Lee, he might reply in a couple of hours once he's woken up

No need to earth or bond.

No need to earth or bond.

That's a bit of a sweeping statement mate imo. If extraneous it would have to be bonded. There is no mention of how the conduit is installed. As its for CCTV there is a good chance the conduit could enter the building from outside. We don't know how the conduit is installed outside.

I read it as the op was using it for cctv drops or in places where cables couldn't be hidden or clipped. I would be very suprised if these cctv steel conduit were buried and introducing and earth path into the building, as the cabling is cctv no dangerous voltage will be running through the conduit at most poE would be used still less than <50v or BNC sytem more commonly using 12v. If the op could give more detail to the exact use of the steel conduit then wee may be able to offer more unique advice to your post.

Yes you are correct in the way you understood it. Cheers
