I think if I just disconnect the main earth and then take a wonder lead either from the MET to the steel or the steel bond and see what IR I get, if its above 23,000 ohms, then thats good is it not? and surely that confirms that its a good enough earth?
 
WPD don't even record it, I have spoken to them about lost neutrals before and they say there is more chance of finding a needle in a haystack.


That is my opinion too....
But tell that to some here that reckon they have seen it happen on numerous occasions. When what they really mean is, they have heard 3rd hand stories from others that know others that have seen a broken neutral. lol!!

Generally long before a neutral joint breaks, it will go high resistance, and it's normally during this time the faults are noticed and rectified

I think you'll find it'll be the other way round, ....if it's over 23K then the structure isn't considered extraneous. The betting is that you'll be very lucky indeed to find a steel structure such as you have, that won't be extraneous. I'm betting it'll at the most a low single figure!!
 
then again, last year i had a call-out to an elderly disabled gentleman... no power. volt tester into CU on incomer. L-N 0V. L-E 245V. SP came out @ 6 p.m. dug up road. open circuit N joint due to corrosion by infill materials. estate only built 15 years ago.

Thats what I meant, sorry, so if its a low single figure as you put it, whats the problem is using that as the source of additional earthing?
 
I'm just bumping some of the older threads in the general electrical forum that had a lot of replies. They might not be current topics, if they're not, just ignore them and they'll soon drop off the list. If you DO wish to add a reply and get the conversation going again, feel free to do so. Your input might help somebody else in the future.
