I have a 30 A ring circuit and wish to install a 20A double pole switch on the ring to feed a single socket.
( The 20A double pole switch will be above a work top and the socket will feed a washing machine )
I am assuming this arrangement is ok. I have never seen it in print or DIY books. The suggestion is normally a Fused Connection Unit feeding a socket(s) or flex outlet socket.
Although I appreciate the 20 A value refers to the outgoing circuit, there is a possibility the cables on the ring side could be "carrying" 30 A.
This makes me wonder whether there is a maximum current for these terminals?
Is it the case that if you can get the cables in the terminal housing, there will not be an issue?
For example, could you install a 13A Fused Connection unit on a 40A radial circuit?
