if there is no earth coming out of the cut out what makes you say it is TNCS? if it is TNCS there would be an earth point block etc. what makes you say TNCS?

I went to do a PIR today and found the same thing, installation around 10 years old (I'm guessing) all equi and supplementary bonding in place and in general a good install but no earth connection at all.

Ze was reading 12.7 ohms due to pipework I guess. I have connected MET to service head and now Ze is 0.07.

Tried to ring EDF all day to confirm supply is PME but got given around 7 different numbers/departments. Gonna get electricity bill from the client with account number etc so I can ring up the supplier tomorrow to confirm PME. Was I right to connect the earth myself today? Surely safer whilst I await confirmation of PME?

How do you know that you had a PME supply?

It may have supposed to have been TN-S or TT.

You've now made it TN-C-S, but if there are no Protective Multiple Earths on the supply then TN-C-S can be very dangerous.

I know with the DNOs you never know... but would the have put a PME service head in if PME was not available through the neutral on that supply?

Though if its a none PME head and he has just lobbed it in with the neutral, then thats on much more shakey ground becuase its obviously not a PME service in that case and your are bodging it into one with no idea whether the network work which needs to be done prior to installing PME has been done or not
