So you won't be installing the CU but you're designing constraints into how the electrician can do it?Surprise surprise part p again ?
I haven’t even began to think about starting this job yet I did intend to run the cables myself and get a sparks (who has done work for me in the past) to install a new CU.
I really couldn't care less whether you want to comply with the Building Regulations or not - only you know how obvious it will be that you've had notifiable work done, and only you know how you'll deal with the lack of certificates if ever you sell, but if your idea of "etc" is that the electrician will notify the council that he did the work then you should be aware that he won't - it doesn't work like that.And do all the testing etc.
So if it's being done over time, at what point did you plan to get the new CU installed and the testing done? What were your plans regarding the testing of the circuits you install or extend before that point, and after that point?And as this work will be done over some time I was looking for the easy option.
And why isn't it just as easy to loop through the switches as you go, stopping whenever you've gone as far as you intend to at that time?
You seem a bit reluctant to take advice which does not fit with what you've already planned to do....some of us are just looking for some advice on how to do the job safely.
Not hard at all, but once removed you've got, in effect, 6 circuits to test rather than 1 or 2, so expect it to take longer and cost more.as for testing/ faultfinding etc how hard is it to remove the ends from the breakers.?
