The datasheets for MK 'Logic Plus' ones say the following (see below). One would obviously expect the 'socket aspects' to comply with BS 1363-2. BS 5733 is a very 'general' Standard ("Genersl Requirements for Electrical Accessories") ...I just wanted to ask if there is a British Standard I should look out for when purchasing wall sockets with built in USB sockets?
Whilst that is obviously true, it's no different from any other "fake goods". The UK is constantly flooded with such fakes of all types, and not just "designer goods", CDs/DVDs etc. etc. since there are far more frightening examples- there have, for example, been cases of 'fake spares' for aircraft, and it appears that a frightening number of fake medicines find themselves into the UK supply chain.If there is a standard there is no guarantee that the socket complies with it. Some of the low cost imported device are likely to NOT comply.
Interesting. As you can see in what I posted above, the MK ones do not claim compliance with IEC 62860. On the other hand, they do claim compliance with IEC 61558-2-16 - what does that relate to?With regard to standards I believe the relevant international one is IEC 62680. This is essentially a straight copy of the relevant USB-IF standards. However the version based on USB Type-A receptacle seems to have been withdrawn in favour of a version using the Type-C receptacle. This is logical because it allows powers up to 100W (so far). I am not totally certain whether such a receptacle would have the USB logo to indicate compliance, or whether this would not apply if tested to IEC 62680, but the only compliance procedure I am aware of is the USB-IF one. It is pretty clear that the vast majority of existing combined 13A sockets/USB receptacles (if not all) do not carry the USB-IF compliance logo.
but with the RCD protection used today the danger involved with a socket failure is low.
Depending upon how wide is their definition of "power transformer" (I hope that our resident pedant is not reading this ), it sounds as if that might well be an/'the' appropriate Standard for the 'USB part' of one of these accessories. doesn't it (although you mentioned only IEC 62680) ?Safety of Power Transformers.
Interesting. Do I take it that the modules are 'Class II', such that nothing which happened to themwould trip an RCD?I fitted 2x lap Euro module usb chargers at my sisters house. They were both used to charge a smart phone and or tablet nightly. Both failed within 2 years and both tripped the RCBO when they died within weeks of each other but failed open circuit so the RCBO could be reset.
