Hi
I'm curious to know, but if you have an RCD on the main fuse board and an external socket with an RCD built in, assuming both RCD have the same level trip fuse, am I right in think that the external socket RCD will always trip first and that the main fuse board RCD will not trip?
Perhaps I'm not asking the question accurately but I think you get the gist of what I mean.
