Are recessed power sockets available in the UK

Any idea of vintage? I'd say almost certainly pre-war and, at a guess, suggest they may have been designed for DC because of the safety feature to prevent pulling the plug when turned on.

I've never seen one of them in all my career! Looking at the design and materials I think its likely to be from between 1920 and 1940 ish, but it is very unusual as BS 546 would have been the standard plug / socket by this time.

Oh wow 17 multiple posts from this crappy forum. That must be a new record!

and by being unfused mandates that no appliance (no matter how low it's power requirements) can have a suitable small flex*. In addition, with these unfused connections, you severely limit the power of devices you can plug in and/or require vastly increase the amount of cabling required and ways in the distribution board.

* Unless we turn round and say all our thinking on fusing to the size of cable is wrong.

I'm not sure I understand your meaning.

If fuses are not related to the size of the cable - to what, then?

I was making the point that if you go the continental way then you no longer have any protection related to the size of the flex.

* Unless we turn round and say all our thinking on fusing to the size of cable is wrong.

Note that BS1363 does not require the fuse rating to be lower than the rating of the flex. For 0.5mm flex it says a 3A fuse should be used unless this poses a problem with inrush currents in which case a 5A fuse should be used. For all other flex sizes it lists it says a 13A fuse is fine.

But not a 13A fuse with 0.5mm cable ?

In the rest of europe they seem perfectly happy to put 0.5mm flex on unfused plugs.

What happens when there's a fault ?
