    Do you mean a G59 relay? If you do I know what they are what they do and why they are needed. Can you elaborate any more or is that it?

    This is the value I have from the generator this doesn’t seem dissimilar from what I would expect from a fixed install.

    Maximum zs generator and rubber box

    That is the value given after doing a test with a meter. The generator is fitted with a PMG I’m sure this was meant to stop this happening or at least help? So let’s cut to the chase am I missing something or do the values on the chart still count on a generator fed installation? Thank you...

    Maximum zs generator and rubber box

    The generator when tested produced a fault current of 2.8Ka The generator is running prime. The generator has been serviced every 450hours I have recently started working for this company after 14 years in fixed wiring, but maybe it doesn’t transfer over like fixed wiring?

The people that done the renovation then get their electrician in to do an EICR because the electrician who done the work on the renovation is AWOL. No corrective works...
