content: While I was trying to find a particular datasheet of an RCCB, I came across this catalogue (link below) which has a photograph of a distribution box in which they wired the RCCB incorrectly!The Red Live wire is connected to the N (Neutral) terminal of the RCCB. Major Goof-up by Schneider Electric!!!!!!https://download.schneider-electric.com/files?p_enDocType=Catalog&p_File_Name=Acti9K_India_Catalog.pdf&p_Doc_Ref=Acti9K-India-Catalog

content: There's actually a very good chance it doesn't care about the polarity - and they were at least consistent.Pretty sure India's the only place they offer a hobbled Acti 9 range and feel the need to draw some wires on with Paint for people...

content: So which side is the switch on? Looks like it's neutral... Maybe they figured that live is the one to switch and painted it accordingly.

content: You shall be more concerned about the thin red wire going from the RCB to the bus bar.Also, typically, breakers are wired top to bottom, not bottom-top. But either way - it doesn't care, neither does the RCB care about which side is the N and L. Not sure why there is the N drawn at all.

content: Be a little careful here, I have come across RCDs where they only tripped the live(So NOT usable for isolation!).Trashy design, sure and I don't think Schneider would go there, but when you encounter someones contractor supply house branded unit is is worth checking the markings.Regards, Dan.

content: Haha, I'm not a big Schneider fan, they are nowhere near as good quality as Merlin-Gerin were.That does sound especially crappy though, and I never believe anything is isolated until I've proved it, probably why I've only had 1 shock in around 40 years of mucking about with things that could kill me...

content: Oh yea, MG did nice stuff.It seems that almost all of the manufacturers in this space have been borged by Eaton.Regards, Dan.
