Found it, Wieland GST18, rated for 16 A/250 V.

I think those modular connectors (can’t remember their name) are rated for 16 A. They’re quite popular for commercial lighting and IKEA used or uses them for modular power strips.

Don’t bother measuring, start tracing the missing earth connection. Unfortunately not the ideal time of the year to crawl around lofts trying to find junction boxes buried under fibreglass in most of Europe.

In an ideal world you‘d probably put both fused connection units onto the ring instead of running a spur cable to each of them from the socket because that saves you the hassle of having four 2.5 mm2 wires in one socket terminal. In practice that involves moving one leg of the ring from the...

The only technical arguments I can see are strain on the solid copper conductors and strain relief at the other end of the cable. In theory someone tripping over this contraption could yank on the cable hard enough to break it at the terminal in the next socket, assuming the cables run in...

I‘d think your best way to code this would be along the lines of adequate fixing of the T&E. I‘m sure it would be quite rare in reality but in theory solid copper cores could break if moved around enough.

At least the stuffing gland hopefully provides strain relief. Most times I‘ve seen setups like this there was flex with exposed cores hanging out of the pattress box. PS: that floating power strip wasn’t plugged in. A Swiss news web site tracked down an entire album of pictures from that event...

Two random ones I found...

These days you can get pretty decent battery-powered LED work lights cheap as chips. One of these can light up a whole room and last for several hours on one charge. They start around 20 quid I think.

No it wouldn’t. A radial circuit would most likely come down through sockets 1 and 2 and split at socket 3, one leg going right and one left. In fact, you‘d use considerably less copper than with a ring.

I read that as „sockets that do comply with the listed standards may be used“ although you‘re definitely right that 553.1.201 explicitly mandates shuttered sockets.

The quote on the previous page explicitly mentions BS EN 60309-2 and one could most certainly supply an entire house from a blue 63 or 100 A socket.

The main question is strain relief. I‘ve seen this a few times with standard pattress boxes and 20 mm of inner cores on show.

Yes, that’s what I wrote in my initial post, I just missed that the 7p price wasn’t for one piece.

Not really surge protectors as we know them. These gadgets monitor the supply for slow voltage increases or drops and disconnect until the voltage is within the set limits again. For brief surges they‘re useless as far as I know. They‘re quite popular in various countries e.g. Ukraine, Russia...
