Which paperwork?

Hi again

Getting certs together for my first Elecsa assesment.

My project was a CU change at my brother's flat. Notified building control as advised and completed, tested, energised and filled out the certs. All good.

Building control came and inspected the work and advised on some further work to be done, which included making good the stud wall behind the cu to improve fire barrier, (he felt the existing hole the cables were fed through the wall was too big and would allow spread of fire), I also needed to extend the conductors within the cu as he felt they could be easily placed under strain if someone was adding additional circuits and breakers, also wasn't happy with the route of the new earthing conductor (with the angle it entered the header unit).

Anyway cutting a long and tedious story short, I removed the cu and boarded behind, moved the cu 30cm to the left giving more length to the conductors (saved crimping them) and replaced the earthing conductor with a longer one allowing a better route. Re tested all circuits, and the ze.

Building control came and rechecked work and were happy with improvements.

Down to the question, do I have to issue a new installation cert for the rectification, or can I get away with a minor works, or can I just attatch the new schedule of test results to the existing cert?

I forgot to ask the building control spark.

Many thanks.

My opinion, don't bother re-doing any of the paperwork, leave it as it was when you did it originally. All you have done is move it a foot, that wont have any effect on your tests etc. So do as you have said in you last sentence. Elecsa man shouldn't be concerned as long as it is compliant, and it must be for LABC to be happy.

Personally, correct me if im wrong....but i wouldn't say moving the CU over warranted anything. As regards the earthing conductor, a minor works? as its a modification? can't see this warranting a full new cert.

- - - Updated - - -

....but then again its just a conductor, everything else tested fine. Yeah ignore me as Sirkit said leave it.

makes me wonder how many db's have been changed for elecsa/nic assessments, did 1 for mine

Thanks gents. Re test came with slightly different results, but I had bought a new tester in the meantime and used the new one to test. The only significant difference is the PFC which changed to 2.84ka from 1.47ka and the ze reduced to 0.10 ohms from 0.14 ohms. On a TNCS system. All still within limits. I ommited the fact I also replaced new meter tails for longer ones due to cu now being further from meter.
