Could someone give a definitive run-down of all the similar-sounding 3-letter acronyms that apply to these modern fuse units in the UK? By this, I mean the modular switch components that we now use instead of wire fuses.
Also, how do they work? I had an idea that they sensed current flowing in an earth wire, but today's experiments have proved differently.
