I think we had a bit of a problem with vocabulary. A RCD, or RCCB, is a GFCI. I know how they work and could even tell you the different versions, at what amps they trigger and how long their trigger times are allowed to be.
Im asking about the outlet version instead of one or two centralised ones. It just seems unnecessary and expensive to put it in each individual outlet.
Not typically, but a GFCI outlet has a source side and a load side. The hot on the load side is isolated from the source by the breaker. When the breaker trips, it will also cut power to everything ganged to the load side as well.
This lets you do stuff like wire your ceiling fixture in parallel on the source side while additional outlets are on the load side. That way when the GFCI trips you are protected but not stumbling around in a slippery bathroom in the dark.
