Minimum Number of Circuits Competition in a Domestic Dwelling.

Zoomup
I am starting a competition for all forum members as to the least number of final circuits found supplying a domestic residential installation.


Yesterday I worked in a bungalow that has three final circuits at the consumer unit supplying the whole domestic bungalow.


1. Lighting.


2. Sockets.


3. Shower.


The lighting circuit supplied the whole building.


The sockets were supplied by a B32 M.C.B. and comprised two ring finals circuits bunched together. (Which I later separated).


The shower might have been the old cooker circuit as the bungalow had no cooker circuit. It had a gas cooker.


So who can beat that?

    Last year I worked in a bungalow where an electrician had just installed a sixteen way CU in a bungalow that originally would have had a three way board.

    No, no Andy. We are looking for a smaller number not a larger one. Now please concentrate or I'll have to send you to the headmaster. And put that away.

    Ah!


    The three circuits did many years service, having installed a sixteen way board to serve the same purpose there was mention of arc fault devices and I pointed out that as it stands at the moment that would mean fitting a thirty two way board to do what the the original three way board did at a cost of several thousand pounds.


    We know you like YouTube videos, have a look at a Wylex AFD promotional video  the thought seems to be that four circuits are adequate for an installation and make the consumer unit less than nine hundred quid to buy, so perhaps four circuits is it what is actually needed, but I’m sure that in most cases we can get it down to three and maybe even two.

    Hello Alasdair,

                           the judges seem to be a long time discussing the wind-up radio.



    The question was final circuits and the wind-up radio is only a consumer - maybe it counts as half a final circuit.....


     




    You seem to be much too bright for this class Alasdair, I think that we will put you up to Mr. Stern's class next year. Wind-up radios, consumers indeed. What ever next. And where's last week's homework? Has anybody got any sensible answers here? And just to think that I could have been a vet.

    Of course the winning answer has to be zero (https://www.bbc.co.uk/news/uk-northern-ireland-48202236) but I think that is probably not the intent of this competition.
