This is a question "You're doing it wrong"

Chthonic confesses: "Only last year did I discover why the lids of things in tubes have a recessed pointy bit built into them." Tell us about the facepalm moment when you realised you were doing something wrong.

RCDs are definitely not replacements for fuseboxes
They serve very different purposes. In general:

Fuse boxes are there to prevent damage to equipment.
RCDs are there to protect people from electric shocks.

An RCD won't prevent your stereo catching fire if it has a short-circuit failure and if you touch the live wire of your domestic supply, you'll be dead and crispy before you ever blow a fuse.
