Earth arrangements confusion

[davesparks]

Thanks for the replies chaps, that was a close en Wiko. My son's having an extension done. When they were digging the footings, they found some unexpected drainage pipes. Thames Water came out and camera'd them, and found another waste pipe. Both were 3' feet down, and if I'd look for a place to put a rod, I'd hit both!

If this 18th proposal goes ahead, it might prove expensive.

With all little bit of planning it should be possible to arrange to use the reinforcing in the concrete as the earth electrode on new builds and extensions.

I understand that's the provision. However, if the requirement for earth rod is applied to 132.16, and I'm putting an extra socket in an old terraced house in the town centre, it's going to be difficult and not cheap.

If I stand corrected I thought the draft said on the lines of preferably. I think that they will accept that when you go around to Mrs Muggins house to fit an extra socket it would not be practical to go and run earth cable outside to a earth electrode.

Reg 542.1.201 .........Additionally, there shall be an earth electrode, supplementing any earthing facility provided by the distributor, in accordance with 542.2.3 (which describes earth foundations).

Still not quite clear on this draft reg, perhaps I (and others have read it incorrectly?)

Oh dear - "shall" has no wiggle room in it ... let's us hope there's a clause somewhere that can keep up from this one's grasp.

Back to my post.
Should of mention the service head is 2 separate connection blocks

And there is no earth coming off the neutral.

2 cables come in from the roof stright to the service connections

I'm confused having just read this thread....first it was a possible TNS with a strap on the sheath....now it's two singles coming in overhead?
Am I missing something?

 

[alan132]

Yh I couldnt confirm it then later I explain it was a tube that the cables come through

 

[westward10]

Any chance of a picture.

 

[alan132]

Will have to get one when I go back.

 

[westward10]

What is the supply, the lower swa. Can you show more.

 

[telectrix]

bigger pic would help.showing where all them cables go to/come from.

 

[Deleted member 9648]

The lower SWA is an outgoing circuit......the incoming supply is top left of the pic and is not completely shown. There appears to be a braid connected to the MET, where does that go?

 

[alan132]

That white unit is what I have just installed

The service blocks are from the overheads

The earth cable goes to a metal pipe that has the service cabless in then a 2.5mm cable goes to the ground where a earth rod is
