Wondered if anyone else found it odd that we are only required to give Zdb instead of Ze on the above cert,since
the earth reading could be coming from pipework or next doors main protective bonding?
Thanks for any replies,

Are you suggesting disconnecting the main earth conductor for testing should be a requirement when replacing a faulty light switch?

IF you disconnect the main earth conductor you should first check for DNC (Diverted Neutral Currents or Broken PEN)
Quite, and maybe turn off the whole building rather than just the board for the lighting circuits or whatever. It depends, if it is in a bedsit with one fuseboard, maybe that is not a bad idea , especially if it looks a bit rough.
On a large multi building campus, no, and as most things are in between it will need thought. At best a 'consider if this test is required' not compulsory pleawse.
