Why? If they haven't tested it to BS1363 because the testing would impair the USB charging functionality, then they can't claim conformity to that standard.

Why? Because I find it very hard to believe that a company like MK would deliberately market a product if they knew that operating conditions which could theoretically arise in normal use would impair one of its functionalities. Apart from anything else (reputation, PR, 'morality' etc.), that would mean that it was not "fit for purpose"

Well, I can't imagine that they would market a product that has two functions without being able to demonstrate conformity with the standards applicable to those two functions. But they do, it seems.
As I've implied, I can't imagine that either. That's why I have suggested that perhaps they can "demonstrate conformity with the applicable Standards" but, because of the 'mixed' nature of the product believe (rightly or wrong) that they are not 'allowed' to claim/declare conformity with those Standards.
I think I'll ask them!

I can't imagine why anyone would think that, but yes. please ask them and post their reply.
Well, I suppose they could possibly have thought (per my initial question to you) that something which included more than just 13A outlets was "outside of the scope" of BS7671 (and similarly for the USB bits) - although, unlike me, they really ought to fully understand such matters! I'll yet you know if they have anything useful to say!

"In due course" has come, but the response from MK is totally useless. I asked them specifically whether their double socket with USB charger ports (K2743) was compliant with BS7671 and/or BS EN 62680 and whether their dual USB charger module (K5837) was compliant with BS EN 62680 (and, if not, why not?), and all their response has done is to essentially copy/paste from the data sheet of the K2743 (or something very similar), which I have already seen and commented upon!
Sigh!! I can but presume this has to be taken as a denial of the compliances I asked about - so BAS can't have the sockets on his ring final!MK Technical Sales and Service Dept. said:

The 13mp FCU method is the best way forward in this case, in order to be Compliant with the Regs. MK K330 Whi does the trick.
Thanks. So either they don't know, or the product doesn't conform. Either way, I won't be using any of those!
Remember when MK were a high-quality manufacturer?
I've just received the MK usb socket and usb module so will have a proper poke about soon. The module uses a 5A single pole microswitch to switch on the supply, the socket is powered all the time. The instruction manual says to disconnect the socket before insulation tests. Thanks a lot MK. The module will be fine insulation testing. The socket is made in the UK, the module in Indonesia. The module is not the same white as the module plate, but they seem to be made of the same type of soft plastic. The frame is very flimsy (also made in the UK). Weren't the frames the same hard material as the sockets before?
Both say they can supply 2A max total load, from either one socket or across the 2, which is different from some of the product descriptions which state maximum 1A from each port.

Thanks. That's consistent with the documentation I've seen.
As expected, then.
2A total, from one or both sockets, is what the documentation I've seen says for both.
Do I take it that socket does not bear a BS1363 marking, and that neither mention BS EN 62680?
Kind Regards, John
No BS1363 marking, the socket is marked BS5733 which is for other accessories not covered by other BS numbers. I can't get any more information on BS5733 as the document costs £234.
Both the socket and module are marked IEC61558-2-16. That document costs about £135!
