This has thrown me - obviously wet behind the ears.
A customer has asked me to carry out an EICR - but when I get there - it seems one has been done already....
It states 'no earth, no RCD'. Sure enough when I looked around there was a new service head from the DNO-very long tails?..
And no earthing conductor - as in no Ze......
So I phone the DNO - they say that yes they have not provided an earth - yes that they can provide one (TNCS). That I get....
But then they say you can just install an RCD main switch? That's what's thrown me - I know you can/should do that for TT systems - but that's based on some sort of earth electrode somewhere.
I can't find one?
Is this a case of install earthing electrode and RCD or get DNO to provide an MET?
