Is this junction box installation acceptable?

This junction box has been installed by my builder's electrical worker, the void above the box is the ceiling space on ground floor

is this acceptable for residential installation?

  • It gets better than that

    Installer tried to cert that there was a pre-existing open circuit on the PE ring

    This wasn't actually the connection causing the issue, these lever terminals suitable for 6 - 25 ², or the top connection might have just been clamped

    The correction isn't much better

    have to double check these connections too

  • Who ever they are working  for, which a one man band, arguably might  be the end customer, if they designed the installation, or far more likely in fact themselves - F. A Bloggs signing on behalf of Fred Bloggs Electrics Ltd, sort of idea, but equally it may be signed as Mr A Technician working on behalf of a house-building company or British Gas PLC ....

    The exact use of the forms varies a bit, and some companies have their own pre-print  variants . The essential info has to be the same - the test results, what was done, who did it and, critically,  how to get hold of them.

    Somewhere the paperwork has to allow you to trace the person or organization doing the work and signing it off as compliant. If the paperwork already  has the company header it may be that info need not be duplicated.
