From the code breakers book,which is a good buy,no mention of the 1667 ohm readings,my thinking if it don’t comply to the Zs measurements,then it don’t comply.
No more sticking a Rcd on that circuit,that’s if anybody does,to protect it .

Probably,it also means that,the high loops cannot be solved by just putting a rcbo in situ.
Even though this is contradicted in so many other topics on that subject.
 
Regs says 1667 ohms. So no code for high Zs because the regs says it’s ok with RCD protection?
Plenty of places around the country with high Zs readings have RCD protection to get round it. Just a thought at looking at it from the other direction, I could very well be wrong.
 
Question

Why is the earth fault loop so high

Answer

Who cares just stick an rcd on it

Not really a great diagnosis or solution imo
 
Because I’m on farmland and there’s nothing but rocks down below? ‍o_O

I’m not even sure why I’m following this thread or why I’m replying :tearsofjoy: maybe because I’m on holiday and the sun has finally gotten to me :tonguewink:
