With reference to 433.1.204 and cable as installed has min capacity of 20A if protected by a 30A or 32A. If the protective device is reduced to 20A how is the new minimum as installed capacity calculated or arrived at ? I've been looking in the Electrical Installation Design Guide, but the answer is avoiding my eyes.
This quote I suppose that the overloading could occur in say a commercial kitchen in a restaurant or pub.is Zoom's, hence my italicisation of it!
Twenty years ago I inspected and tested some 50 or so pubs and couldn't believe that a manufacturer made a twin deep fat fryer each having a 3 kW element and it came with two separate 13 A plugs. These would inevitably be plugged into the nearest double socket-outlet. The manufacturer's logic being that they wouldn't sell any if a dedicated 32 A circuit had to be installed as per the traditional cooker.
I also learned to only have packeted condiments with a pub meal having witnessed the ever so pretty dish with brown or red sauce in it being brought back from the table part used and poured back into the gallon bulk container for the next eager diner to sample.............
Interesting wiring of yours but fairly typical I'm afraid.................
