no earth

[sima24]

Hi, been to look at a rewire today and no earth connection at all. Tried to contact supply company to enquire weather the property is connected to a pme system but no joy after holding most the afternoon. I presume supply company doesnt have to supply an earth but just wondering if they would upgrade to pme or not? Or possibly it is a pme system but earth has been disconnected at some point (no sign of pme label tho) any views appreciated. Thanks.

but you wouldn`t though....would you...lol

Oh yes he would, cause the BGB told him so!! lol!!

 

[Engineer54]

you dont take the risk though strops.....
a properly sited, well installed TT system would not be unduely affected either way....
we always take the worst case scenareo strops when dealing with electrical installations.....

Don't waste any more breath on the matter, he obviously knows far more than us!! ..lol!!

You are permitted to have a Ze for a TT supply up to 200 ohms - Above 200 ohms it may become unstable..
but you wouldn`t though....would you...lol

So considering my Ra was 125 in the first place I should have left it then, but I didn't!
Anyway I'm not bothering to waste any any more time discussing the subject (I see no-one could be bothered to answer my questions), as it is descending into taking the ---- and ignoring genuine discussion, as usual.

Bearing in mind with my service bonding connected I am getting 0.45 I'm satisfied I have a good EFL path.

Have i missed something along the way??? Why are you installing a TT system if you have a Ze at the service cut-out of 0.45??

And no-ones taking the ----, you asked for advise got it, and then you start pulling it apart to suit yourself!!

 

[Stroppy]

Yes you have missed something. It is an existing TT system of which I was upgrading the rod as it was giving 125 ohms, which technically satisfies the BGB, but it reality is a bit rubbish. The 0.45 is the resistance of my bonded pipework (underground gas and water pipes) when tested without the earth stake (new or old) connected, not the service head. As I know we shouldn't rely on bonding for our earth path I set about replacing the rod, which got it down to 44.

I was joking about peeling back the plastic off my incoming cable and wrapping the earth wire around the armour.

so lets say you got just within 200....
would you be satisfied with this...?
as far as BS7671 is concerned its good....
but its time to ask yourself what you truely believe....

 

[DPG]

He's already said that he had 125 ohms so he decided to improve it. So no, he wouldn't be happy with 200 ohms. Daz

thanks Daz...
as i said...if he had got to just under 200...

 

[DPG]

Well, if he's not happy with 125 ohms, then why would he be happy with 'just under 200 ohms'? I don't get where you're going with this? Daz

 

[GLENNSPARK]

i`m just being picky...
no , really what i mean is the regs state 200 ohms....totally ridiculous...
even 100 would be pants...
well planned and sited rods can return almost TN levels .....

At least one person can see why I'm getting exasperated! I wasn't happy with 125, so upgraded the rod, and they ignore that and still say

"would you be happy with it?"
"Oh yes he would, cause the BGB told him so!! lol!!"

And when the existing rod is in a rubble-free position they still want me to move it a metre down the garden to avoid non-existent rubble. Now who's blindly following the regs?

this isn`t in the regs strops....

 

[Stroppy]

Good. Next rod I do I'll chisel a bit of wall out so the rod is touching the wall and there's room for the sh1tty green box to go on top of it!

 

[ackbarthestar]

surely that green box doesn't comply with current regs. it should be green/yellow, with neither colour taking over 70% of the surface.

Wrap some yellow tape round it........
