It's been, oh, at least a week since the last RCD question so I thought it about time for another...
Can anyone tell me whether or not the 'orientation' (in terms of wiring up) of an RCD matters if there are no 'Live In/Out, Neutral In/Out' markings to indicate? I'm talking live/neutral on the left/right as opposed to swapping mixing in/out on the top/bottom.
I have taken a picture of the shematic of my Beko RCD at
However, does it matter whether 1 or 3 is used as the live input (with the corresponding output on 2 and 4)? Does the wiring of the test cicuit dictate the proper orientation? Or some other factor?
I ask because I wish to use it such that 1/3 are live/neutral in, and
2/4 are live/neutral out. This would allow the 'protected' MCBs to be run on the left of the RCD on a busbar connected to terminal 2. The current orientation is the opposite of this (i.e. 4 is the protected live out).Thank you for getting this far in what is likely a simple question heavily disguised in my ramblings...
