No Main Earth Help

[sparkie710]

Hi, im only just recently qualified and have come across a situation I have never experienced yet, in a block of flats in the hall are the meters that then go off to a switch then cables run into the house, there is no main earth in the house!! the tails are about 10 - 16mm cant remember now sorry. so I was wondering who has to run the earth in and if its me what size earth 10mm ? just want to clarify and what tests do I do and results should I get to be able to pme the system ? thankyou

If it's the DNO you will need to contact them,

 

[sparkie710]

they don't wanna know there saying its the lectrics mans responsibility but isn't there tests you can do ?

Adiabatic equation. Installation cert for main earth for me as you are changing the characteristics. Others will have other opinions .

 

[Gazthesparky]

What are you actually saying is there no earth from the meter position into the house?
if so this is the responsibility of the sparky

If there is no main earth provided by the DNO first enquiry is required to find out if they could provide one. If not then you will need to provide a earth rod and make the installation a TT system

A picture of the intake and meters would be good to try and work out what's happening

I thought you was referring to sub mains to flats? You describe things like my MRS :001_icon16:

?? You cant just PME a system this is not your area to mess with.

Ring the DNO and ask if PME is available in that area.

It's a bit ambiguous I guess that's what he's refuring to needs some clarification. Seems strange that the exsisting sub main doesn't have a earth from the meter position into the house consumer unit

I can't make out head nor tail of what the OP'S actually on about, he can't seem to answer simple questions on his query either!! I'll wait in anticipation of any photo's that are forthcoming before making any comment...

What is disturbing me, is that he doesn't seem to see any danger or consequence to making his own N-E connection. So let me tell YOU now, in no uncertain terms ''NO'' you CAN'T bloody well PME the supply just to suit your needs!!
