RCD Connection Agnostic?

Just had a timely email from Wylex technical support - "Wylex RCD’s can be feed top or bottom".

So, that's one manufacturer down, just 99 more to go

I certainly have some Wylex ones wired in the 'less usual' way. It seems that you can probably add Hager to your list, albeit this is over 7 years old (click here) - where, as you can see, it was said:

I contacted Hagar technical regarding this and their answer was
"It makes no difference to which the incoming or outgoing side are connected, and will not affect the operation or safety of the device"

Kind Regards, John

So for your device, the the manufacturer had marked the casing indicating an in and out, so direction mattered. Was your RCD possibly a RCBO? They are asymmetric and can only be fitted one way round in a CU. Just a thought.

No far from it, these 3 or maybe even 4 modules wide and in those days used as the main switch. and definitely marked LIN & LOUT etc
