Type B RCDs are still pretty rare, but not as rare as type B RCBOs.

Good article; then if a circuit has USB sockets, then what type RCD would it need. Thought it would not need other than usual AC type as the USB ELV bit is separated from LV (at least the bonafide ones) are they not. ?

Great article.

I will defo brush up on the different types of RCD’s. It’s not very well known about the different types. I would never have known the wrong rcd in the wrong installation could render it useless

so is it saying if an installation is fitted with the most basic types of rccb or rcbos, then later say solar pv is installed,,,, then they all need changing because they wont work properly?
