Am I correct in saying that it does not matter if there is a LN
reversal on the input?

It will always have a correct +/- DC voltage.

The DC voltage across the capacitor will be the same, the difference:
one way it will be referenced to neutral, ie close to ground, and the
other will have 230V superimposed on the capacitor terminals.

I'd assumed Adam meant a bridge rectifier as in

https://www.electronics-tutorials.ws...?fit=331%2C191


but I am prone to be wrong

I saw "full wave rectifier" and thought "single diode". My bad, I should
try reading a little harder.

In which case L-N reversal will make no difference.

Your link is spot on.



And the reason I posted is because I found a LN reversal on a socket
during a EICR.

The tenant was adamant a rectifier would not work.

I was convinced it would (even after a bottle wine of when I posted).

So I asked the collective wisdom of you fine posters.
