no earth wire from meter box

[Jay Sparks]

There is no earth wire going from the earth stake to the fuse box.
Thats easy to digest,its not at the fuse box but it does exist,what size by the way?
It is connected to a henley block within the meter cupboard just above got this bit as well and there is a twisted wire (uninsulated) about 4 strands going from the incoming mains cable into the same henly block. got this as well There is also a connection from mains cable into the neutral henly block is this the same henley block as above but it is all wrapped up and cant see whether its another part of the twisted wires. can you not test and determine one way or the other
I thought "this cant be right, there must be an earth cable going to the fusebox surely" Surely. so with great difficulty I ran an earth wire to the new con good on you



I will never win the lottery but getting this one right has slightly better odds,only slightly but there is always a chance

You have a lead sheathed cable with an obsolete Tns connection.the system is now Tnc-s with the twisted bare wire connected to earth via the rod and now its also connected to your cons unit
You now have a TnsTnc-sTT earthing system simples

Blinking Nora!!!! Is you Misstick Meg??? What are the lotto numbers for Sat????lol You is a wise one my friend!!

be prepared to install new rod or two

Engineer54 will be along to assist shortly.

I thought when I first read it it sounds like a TT with a TNCS sound about it. Will be nice to know what the DNO say.

Reply to des 56..
the wires are 10mm; no the second (neutral) henly block is a different one; yes will test more tomorrow but it was going dark, had no electric and customer was getting a bit aggy.
TNS-TNCS-TT earthing system.. hmm, Well I suppose that covers all eventualities then!!
Actually the new wire I ran I've left unconnected for now as it appeared more neutral than earth... hence my query.

If the DNO say its TT, get another rod installed, (two screwed together if needed) and run a brand new earth cable to the CU. You mentioned ONE 30mA rcd covering the whole install in your first post....I hope this was a misprint!!! You need a dual 30mA rcd board for your final circuits, with a 100mA time delayed upfront rcd. Again, this maybe me miss understanding your post.lol

Thanks for advice - I meant the original was on a 30mA rcd - new one is dual. Am going to replace the original with a 100A switch instead, so no problem with discrimination..
