no earth spike?


A

AlterEgo

I had my water supply moved about 2 years ago but this only occurred to me
today.

The original supply was through copper pipes fed underground and into the
house. The new feed is through plastic pipe. I can find no earth 'spike'
and was wondering if I have 'lost' the earth. Is this a problem or a
potential problem (no pun intended)?

I am not having any shocks or problems of any sort.

Thanks in advance.

Have a look at
http://www.diyfaq.org.uk/electrical.html#system
and you should be able to identify your type of earthing system. The water
(or gas)supply should never be used as the main earth for any electrical
installation although both of them require bonding to the earth of your
electrical supply for safely reasons.

Hi. Thanks for the Reply.

I don't have a digital camera so I cant post a photograph sorry.

It is not 1) TN-S. Two separate wires come in from outside. Along the roof
line.

There is a black box near the meter, about ½ X 3 inch, but no wire to the
consumer unit from it. There is a heavy gauge (green) wire coming from
between the floors into consumer unit but I can not see where it comes from
easily.
Where the 'main' fuse is it says protective multiple earth, is this any
help?

If it says PME near the main fuse holder an earth wire should also come out
of there (bonded to the neutral) and run up to either an earth block or to
your CU

I have cross posted the question on both diy boards so please forgive any
confusion I am causing by putting the same answer on both in the event that
someone else may benefit from replies to this question.


The grey box where the main fuse is, says 'series 7' on it and 'official'
labels from the supplier saying P.M.E. there is no green / yellow wire from
this into my consumer unit, and the green wire I mentioned in the earlier
post goes to the back of the house then between the original building and an
extension added about 20 years ago ( before I lived here ) Would it be the
best option to add an earth rod anyway, or get the PME connected up? Would
the electricity board have to do this? Would they do it without making me
get rewired throughout?

Run a 16mm2 earth from your CU to where the official labels are , then call
the supplier who will come and connect up , they may perform one or two
tests depends on what mood the guy who comes is in. If you're thinkink of
putting an earth spike in dont forget the main isolator ( in your CU )
should be an RCD
or or and
I think this is the best option. Any idea of the cost?
If I have got it wrong then they will be able to tell me.

Thanks all who replied.
