Hi Ex Army
Are you saying all your IR tests are clear with 650 Meg and the leakage is when appliances are plugged in when tested with the earth leakage clamp meter ?

Not just appliances though, he's got 180mA on a lighting circuit, so unless there are some dodgy transformers on there then there's a problem lurking somewhere.
Hi Pushrod
Well as Tel has already stated, becuae of the PME link the neutral current has a several paths, now dependent upon the CNE/PME impedance and the impedance of the protective conductors to earth, then you will find that some diverted neutral current will flow through the protective conductors.
The diverted neutral currents may be from your installation or even a neighboring installation.
Place a amp clamp around the live conductors at the origin on a TNC-S and see what leakage is present,and what the RCD will see.
Now dependent upon current, place a clamp/leakage clamp around the Earthing conductor and then other protective conductors.
See what you find
Cheers Chr!s - was thinking i might have been missing something else
Tel has discovered a new quantum effect: Indecisive electrons
Ohh, distance and direction, you sureAn electron can be found at any distance at any time and in any direction from the nucleus due to the Heisenberg uncertainty principle. Isn't that indecisive?
Although being a topquark, you might consider the uncertainty principle rather convenient
Ohh, distance and direction, you sure
