Perhaps we should give the man a bit of lee-way fellas
I know of many installers who wouldn't know the difference between a test instrument and a Gameboy
There are countless (mainly Niceic) firms who do rewires, where the job is done practically with the installers,who have no function other than a bang test at the end of the day
They may or may not know how to test,its not required of them
Someone comes along at a later date and tests the installations of many gangs of installers
This is not untrue,I have done so many hundreds of times personally, on a sub contract basis
The post may have many years experience and does a fine installation
He is unfamiliar with testing and certification perhaps,but, he is one of countless numbers doing domestic installation who never get an opportunity to do so, even if they wanted
We know its wrong,but it goes on at the majority of large contracted council type jobs
Where he seems to have attracted the wrath of the forum.is by being truthfull and looking to find out procedures on a non contracted job
There is advise available for Diyers on suspect forums,but the guy is working in the industry and seeking advise on an electricians forum
