How to wire Hager CDA263U RCD?

[Filipcashman]

Can I connect the supply line and neutral to the terminals 2&4 and the load side line and neutral out of terminals 1&2

It clearly shows the supply into 1 and 3, 1 would be the live.

This has cropped up before on this forum, and the claim was made that Hager state they can be fed top or bottom.

So, seeking the evidence, I found the very last page of the Hager Residential Catalogue, which gives common technical characteristics for the range (If I'm interpreting this correctly), it does say it can be fed either way:

The schematic clearly shows the feed to 1 and 3 and whilst I agree inverting this may not make a difference the schematic should be adhered to.

Top-feed or bottom-feed RCDs?

Another disparaging Hager-related question: does anyone know if it matters which set of terminals are feed power, and which are load for RCDs? Typically incomer RCDs are fed from the bottom, but the supplied instructions/datasheet (for what they are worth) for the likes of the CDA425U 4-pole...

I do agree the obvious way to connect it is as printed on the device, but it does appear acceptable to do it the other way if there was a good reason?

What must not be done is to feed live from the top on one side and neutral from the bottom on the other, or vice versa.

The Previous RCD is wired this way , its being changed because it’s trip value is 0.3A

Well altering a consumer unit is restricted works and legally should only be carried out by an REC.
