My gob is truly smacked. I would never do this. It goes against everything thing I have been taught.
Ok, and the difference between that and adding to ring MCB is what?New circuit, 4mm radial on its own breaker,
Ok.Electrically nothing.
I don't think that is the reason for 13A fuses in plugs.But it goes against the whole ethos of a ring final: a distributed circuit with current-limited connections. Every connection is limited to 13A, except for a double socket where the max could be 26A.
So what?Your arrangement could allow a current load limited only by the 32A MCB, and for this to be at one point in the ring.
What would you do if you wanted two double sockets (or five) under the CU?
Not according to app 15. If what you have stated is allowed then we can all connect 4mm SWA to ring finals, run it down our gardens and put consumer units on the end.
What, you mean selecting conductors that have sufficient CCC rather than fusing down?
This is fine, if the 4mm2 is connected to a socket or joint DIRECTLY on the ring (ie not a spur), and the cable to the new 5 sockets would have to be in 4mm2 (though the very last one could be 2.5mm2.
I also don't see a problem spurring in 4mm2, then forming an additional little ring from there onwards in 2.5mm2.
Not that I would do much of this in reality - makes the testing a pain for a start.
