Wylex Type C RCBO

[DYCHE4230]

Hi

Am I ready this correctly?

Page 44 OSG table 7.1.

On a ring circuit for a TNS system, No RCD, 2.5/1.5 T+E
A "type C rcbo" is not permitted ZS being the prohibitive factor?

If so does anyone know where I can get a type B wylex RCBO?

Thanks

I'm pretty sure i had a wylex NSB type B RCBO from CEF.

There's a thread on this very subject elsewhere. As far as I remember nobody pointed out this issue with Type C RCBO and Zs. The problem with getting your hands on a type B was definitely discussed though. Additionally, at a recent NICEIC event, the Wylex representatives were handing out literature stating quite clearly that RCBOs on smokes should be used (on non-RCD protected), while the NICEIC speaker in the next room was saying not to use RCBOs on smokes, put them on the lights. Slightly off topic, sorry.

long story short b or c makes no difference on an rcbo
