Single Pole RCBO in TT with Time Delay RCD Incomer

[spark 68]

See the smiley on the end Dave , what with the earlier semantics, plus a discussion on the IET site I was involved in the other day someone else made the point that SPSN could apply to solid N types

Semantics, shemantics lol

Is it not 1P RCBO means fixed neutral and only operates Line conductor
1P+N RCBO means RCD part operates the line & N but overload only operates line not Neutral

1P+N RCBO means RCD part operates the live & N but overload only operates line not Neutral

This is basically what I described as a SPSN type the other day on the IET site

No, there is a standard nomenclature as I mentioned in an earlier post.

Best let Hager know then.

No, the nomenclature is pretty well defined.

Oooooooh! Using big words now are we Dave?!

Thanks for all your help guys.

The RCBO is just a single pole so I'm organising it to be changed to a double pole. Luckily there is space in there for a 2 unit one.

I'm beginning to suspect that the time delay RCD is a bit trigger happy (faulty) so I'm getting that swapped out too.

I did and that's why they are listed as 1P

And you're basing that suspicion on what? A hunch?

Maybe testing it would be the way to go first? But then what do I know?!
