It's possible that you weren't on PME before, and when replacing the main
fuse assembly they took the opportunity to 'upgrade' you.

You should have known what your earthing was before, because it affects
cable calculations and protection methods, and is a fundamental part of
completing a test and isnpection certificate.

No, the cable was not changed, and had only live & neutral. What
I meant was, ought the type of earthing to have been apparent to
anybody working on the system, in the absence of any labeling.

I understand that it is necessary to know, for the reasons you
state, but there was no visible indication or other
documentation.
