Good morning Dave.
On my way back to site now.
Some more testing to do.
Theoretically, a bridged neutral and earth
Clutching at straws here, but -
Earth and neutral is bridged on the load side?
An earth neutral fault to the point where the neutral loop
The test button on the earth leakage relay should work irrespective of whether the neutral is earthed or not.
There is an internal resister
The way that the ELU works, is that the Live and Neutral wire go through an iron core. The core then has a secondary winding connected to a trigger mechanism.

Earth leakage problem. Help.
On reflection I am possibly wrong on the relative neutral loop impedance readings. But I am mindful of your typical earthing arrangement in East London
