Have been asked to fit a surge protector to a distribution board.
The device looks just like an MCB without the switch(it is a Hager SPN 140D/R)
However the problem I have is that the wiring diagram supplied is very confusing as it uses Euro-style symbols which I am not familiar with.
My question is: how do I fit it?
Is it in series with the incoming live? i.e. live in , live out to the main switch then on to the board
Or is it in parrallel i.e. to be fitted across live and neutral, like a resistor?
The diagram supplied seems to show it across 'D1' and 'D2' whatever they are...
Has anyone ever fitted one of these? If so, please help.
Cheers, Crosswire.
P.s. Here is a link to the wiring diagram:
