IR testing a USB socket.

Hence the 13amp fuse in the feed works wonders.

Interesting, given that MK are one of the more reputable manufacturers.

Indeed - but is it perhaps the case the the accessories we are talking about are outside of the scope of BS1363, and therefore cannot claim compliance with it?

Kind Regards, John

BS 5733:2010+A1:2014
General requirements for electrical accessories. Specification

BS EN 61558-2-16:2009+A1:2013
Safety of transformers, reactors, power supply units and similar products for supply voltages up to 1 100 V. Particular requirements and tests for switch mode power supply units and transformers for switch mode power supply units

The other two are generic EMC standards.

Well, the 13A socket-outlets are within the scope.

I would have expected a declaration of conformity to whatever the USB standard is.

That sounds fair enough. Do I take it that it is possible for a product to claim compliance with BS1363 if only some parts of the product are within the scope of that Standard? For example, could a generator, inverter or whatever which included a 13A outlet claim "compliance with BS1363" - and, if so, how on earth would one do a BS1363 temperature-rise test on an outlet that was built in to a generator (or whatever)?

Well, I'm just quoting what it says on their "Technical Specification" sheet - I suppose that doesn't preclude the possibility that the product may be compliant with some Standards not mentioned there.

The generator or whatever couldn't. The USB + dual socket outlet though is primarily a device within the scope of BS1363, and I would certainly expect it to comply.

If they can demonstrate conformity then I'd be surprised if they didn't mention them. The absence of a claim to conform to BS 1363 or BS EN 62680 seems suspicious to me.

I would imagine that it probably does comply, since I doubt that addition of the USB module would materially affect performance in the required tests - but it seems odd that they are not claiming compliance (since they obviously do for their standard sockets). Maybe, despite your view, they feel that it is not within the scope of BS1363?

I've just had a quick look at the Screwfix website - the 'USB sockets' from BG, LAP and Varilight all claim compliance with BS1363-2 and EN 60950-1. However, again, there is no claim of BS1363 compliance for the MK one.

I've just ordered one of the MK USB sockets and one of the Euro module ones as well to see how they are constructed and if they are any good. They're bloody expensive!

In view of the recent discussion, it will be interesting to learn whether either bear a BS1363 marking, since that Standard is not mentioned in the technical documentation of either.

How much power do the use when not charging anything?

The ones which are shutter-switched (like, apparently, the MK USB modules {not the MK double sockets}) will use zero power when not charging anything - or, at least, when nothing is plugged into the USB ports.
