These are MK Logic Plus model no K2747RPWHI5PKThe fact that MK have recently chosen to exceed the statutory minimum requirements on their logic plus series is great, and their outlets will be safe on the 32A supply.
Others don't and, therefore, won't. It doesn't affect my opinion on the standard itself.
Just out of interest, @Elecpleb , what brand and model faceplate have you used?
Well the RCD was supplied with the sub board, and I dont think I will need the space, so I may as well leave it in. I think the sub board is necessary too, to divide up a main circuit, second circuit and lighting; main circuit for the work bench and second circuit for wall sockets for heaters, chargers etcIf the main board is RCD protected then there is no point putting one in the sub board.
I think I would get a sparky in for this to be honest.

The max usage would be two tools, a 2000W router and 2200W extractor so used simultaneously. The cable is surface mounted as its temporary.The good thing about tools is that usually you can't use more than one at a time so no fear of overload there. The sockets could melt and sometimes do but that is usually putting 6kw on the socket and loose connections. The MCB is there to protect the cable actually, more than the accessory. You are just at the top end of 4mm on a 32a MCB so I would not worry about it. Depends a bit on how you installed it such as through insulation and in the sunshine wont help it will derate the cable. Mind you tools up to 4.2kw could be a problem for the socket. 18a is at the top end of the socket rating, per socket now that could make them melt.
Not intending on drawing 32A through it, the consumer unit came with the MCBs and RCD supplied, and I already had 4mm T&E. My question was this suitable as a temporary solution, out of convenience, not design.Are you sure you understand what you are doing? How do you intend on drawing 32a through a socket outlet? They are generally rated at 20a so not even suitable for 2x13a plugs. RCDs in series is a bad idea also. No need for the second one if already protected at origin, however a bad design.
Thanks, that was the gist of itThere seems to be a lot of random nonsense in this thread, not all of it intentional, but clouding the issue of the original question.
Protecting double BS1363 socket outlets using 32A MCBs is normal and standard and 100% compliant.
There are lots of other things to say but that is the important one and I can't be bothered to haggle at the moment.
No, I was questioning what had been impressed upon me, which was that a current up to 32A at the rear of the faceplate could cause issue.To the OP , please correct me if I'm wrong but your initial post gave me the impression that you think a 32 amp MCB will somehow push that amount of current through its connected sockets. That is utter nonsense .
Yes that’s the plan, got two double sockets so good to go for now. Triple check connections.Split that 4200W likely max load across two different double sockets.
As others have said, the faceplate may only be tested to 20A across both outlets.
Also what others have mentioned, the most likely cause of melting would be a loose connection or low quality materials.
