But hey. I'm only getting into this as I'm now working on my own and want to do it right. Hence doing the initial verification course and now the periodic. So am open for any advice. Hence why I checked with the tutor today and will have him double check.
As I will be using the reasons given here to do so lol
Phil I'm afraid your tutor is mistaken. If you change the ccu you must issue an EIC...... Remember "those that can, do. And those that can't, teach"
And Risteards opinion that it only covers the ccu is also mistaken. I've said before on another thread once you have disconnected the final circuits from the supply, you have to ensure they are safe before re-energising them. You can only do that if you know ADS will work, the insulation is up to scratch and there are no mechanical defects likely to give rise to danger. So you're stuck with having to do a full test and all that entails, or you would be working outside the scope of BS7671.
This isn't just my opinion, (and we changed over 500 ccus last year on K&B refurbs) it's the view of our NIC assessor. New fuseboard. Full test.
