Earthing of a conduit

[Jon Lester]

Hi there I work in a shopping centre and the tills are supplied by a chrome pole ( non standard ) that comes from a metal burgess ceiling . Inside the pole is a 2.5mm 3 core flex and a CAT6 cable (non screened ) that supplies the till . This pole does not have any earth . I’m now being asked to use an earth clamp to connect the pole to a piece of trunking above the ceiling via a 4mm cable . Question 1 is this necessary? Question 2 should the earth from clamp be connected to the same earth that is contained in this pole ? And question 3 should the CAT6 cable be installed in same containment as the power supply ?

That is an issue of good workpersonship.

God, give me strength. PC gone mad.

You'll probably find that workpersonship is now verboten in favour of a term more inclusive of those that identify as unicorns.

PC is now not enough for the progressives, you'll have a trawl through the Guardian and find the latest approved term.

A coulper and brass brush on the top would solve that issue, earthing the pipe will not it merely mitigates the resultant consequences of the cable becoming damaged.

I'd settle for a female brass bush you could even add a lockring and banjo to give an earthing point

Is there a proprietary system for this ?

I know there is power poles and posts but this is basically a piece of containment or pipe

In theory it may not need earthing if a double insulated cable and grommets/bushings are used

But the above is ideal circumstances, it may be hazardous as described without the link to the steel trunking
