Possibly overkill in domestic so long as all the sockets are when you

Last thing I saw at work yesterday.

That is as how I found it.

TT installation with no RCD or ELCB.

Is the brown one a replaceable wire fuse or a cartridge fuse?



Blue one? ie blue dots on it?

That's right. I've forgotten the colour code.


White = 5A, Blue = 15A, Red = 30A, and the less common Yellow = 20A, and
Green = 45A

The last fusebox I remember as a child had ceramic fuseholders and Woolworth's
fuse wire was 5A, 15A and 30A as I remember. I've probably got some
somewhere.


And of course open to abuse as you can put 30A fuse wire in a 5A holder.
