Just about to do the final connections at the CU end for my kitchen/ diner refit.
Conundrum: I originally wired this as two rings, one for the left hand side, one for the right hand side, as there was a pretty heavy appliance load one side in particular which even with diversity took up too much of the 32A to leave enough for it to be a single ring. That was going on the online instructions for the appliances in question. Then I checked on the telephone, and was told that one of the built-in ovens needed a 16A supply. So things got shunted around and the heavy appliance load ended up on a 40A radial to a mini-CU feeding the ovens via radials.
Anyway, this leaves me with two rings, now massively over-specified. Which I want to reduce to one ring for that floor of the house, no point in wasting the CU way, and having a more complicated and less obvious layout than it now needs to be.
The two rings run different routes back to the CU, when they leave the dining room they go all the way through a 30ft cellar to the CU. I can easily intercept them near where they enter the cellar, and interconnect them so they form a single ring. But that actually makes the circuit path much longer and is more work than just connecting them both to the same MCB as a kind of doubled-up ring. The latter instinctively feels wrong to me, but I can't put my finger on what would be wrong with it, so I am wondering if I am making work for myself.
(This is all subject to a building notice and inspection so part p comments are otiose.)
