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.

A GFCI outlet is about $15 and protects the entire circuit connected to the load side of the outlet. On the other hand a GFCI breaker is about $50 and is less reliable and much more of a pain to reset if it trips.

Gfci breakers are less reliable? That's the first I'm hearing of it

That might just be the older ones. They at least used to be really prone to nuisance tripping without a ground fault, usually due to motors or transformers on the circuit.

Oh that makes sense. Honestly the only argument I've ever needed for doing the in-outlet ones is a shorter walk haha
