Scary stuff

Yes, I do indeed!!

I pinned up a copy at our local wholesaler...

The back-up device in question was a 3036 fuse, not mcb. And it had a bit of 2.5 in it..... :lol:
 
There are some designs of plug with removable pins, where by taking two, one can produce one plug with two neutral pins, i.e. a totally unfused plug that will look and feel like normal.

On a 16A radial I guess it doesn't matter, but on a B32 backed ringmain, it allows a number of things to be seriously overloaded before anything will cut out. Almost as bad as those unfused 2 way adaptors you can still buy at ASDA for about a quid.

However, as you don't need the fuse at all, until there is a fault that would operate it, you are unlikely to realise if you have a duff fuse.
The saving grace is that a socket anywhere other than right next to the CU is very unlikely to manage a 6KA fault, (and the flex needs to be short and fat too)- from 240V that requires ~50milli-ohms of resistance, and no arc voltage whatsoever.
Much more realistic is that the fault current is in the 500-1000A range, so it is likely not to be quite as bad as shown here, even if you do have aduff fuse.

i realised you could do this from about the first plug i ever wired. cheaper to just bypass the fuseholder though that way you don't need to buy a second plug.

i belive unfused doublers are actually allowed by the BS-1363 standard
(same logic as double sockets rated at 13A total i guess)

and in the unlikely event you did get a 6KA short shouldn't the B32 breaker take it out pretty damn quick?!

Errrr... look at the last post on Page 1 of this topic....

Yes, yes ban, you linked to it first, but it was relevant enough here to warrant another link to it, anyway, haven't you got some 10mm cable you are supposed to be putting a plug on...
