Hi Andrew Gabriel

But hang on, can I place a 20A switch in the ring circuit just like a FCU?

Yes, switching the spur (and not breaking the ring;-)
You have to have a fuse somewhere, be it in a FCU or in the
appliance plugtop, but you don't need more than one, and
it doesn't have to be at the beginning of the spur.

Stupid question alert....

What's an FCU? (Acronyms escape me sometimes....)
