Am I on the right lines, I ask?
I've just recently moved into this house which is nicely equipped with a large 15 circuit CU unit with a split load x2 RCD's but first, I think an EICR would be a good idea to give a starting point reference at least, before any work is done
I'm considering having a Lightning SPD (Cat1 + Cat2?)/MBO fitted with a visual status and replaceable capsule design- (as a definite addition)also an AFDD and it's this latter protection which has me pondering on the best way forward.
The price of the AFDD devices for each circuit with RCBO's seems to be likely to about ÂŁ2k plus a day's (?) labour- so edging towards ÂŁ2.5k for the whole plan to to be achieved
Q1- as these AFDD devices become more common and eventually mandatory in new builds/MHO's etc. I imagine the unit prices will fall but currently they seem to be around ÂŁ120 each- alternatively since fires are not so common and this is not a high risk building (other than rats from the nearby stream nibbling through cables in the garden lights)- perhaps it would make more sense ftb to have a separate housing before the CU for 1 x AFDD/MBO (and the SPD) and maybe in a couple of years consider a full CU update- comments please?
Q2- Am I correct in thinking that whereas 1 x AFDD/MBO per circuit would immediately identify the faulty circuit but leave the rest of the power supply to elsewhere in the house live and still working- whereas one AFDD installed before the supply to the CU would knock out the whole power supply and necessitate an emergency investigation to get the property back on its feet quickly?
So far I haven't yet got any quotes in but my first impression is that few electricians have any depth, if any, experience of AFDD fitting and I would like to at least be able to ask sensible questions and understand what I am told
So thanks for reading this and more thanks, in advance, if you are able to advise me
