Socket Converter 2 Gang to 4 Gang

Does Eterna qualify?

Surprised that it needs a fuse, since I would have thought all the sockets could have been treated like spurs?

Yes, but more than a double socket on a spur does require a fuse, all of the 3 or 4-gang convertors have them.

I think it's because it's designed for retrofit: if the original was a single 13A socket, the new attachment is also limited to 13A. That way a householder can do a replacement wthout need to verify current capacity of the circuit (eg if this was fitted to an existing spur which the rules say you can't add extra sockets to).

Fitted one of them and I like it - it's not deep unlike others, so it's barely thicker than a conventional socket. There is a green LED for the surge protection which might be annoying in some cases (or tape over it).

Surely, it has to be as thick as the length of the pins of the plugs that go into it? About 2-3 cms?

Of course, I was thinking in context of a ring.

I have seen 2-gan ones and they look a neat way of adding changing a single to double without any mess.

Yes, but if added to a ring, not a spur, probably unnecessary.

If it had two sets of input connectors, and appropriately wired inside, you might count it as part of the ring,

It would have to have 4mm equivalent, in case it was used on a 32A radial.

yes: 25mm - the length of an earth pin plus the thickness of the plastic case

I fitted a 1 to 2 by Eterna. Not here and house was sold a year or so later so I don't know how it lasted. Seemed OK build wise but even to my catholic taste (or lack of taste) looked clunky.

You know you really need bench trunking...

It's nice of them to show you what the fittings on the back look like before you order it.
