    RCBOs with 1 flying wire.

    Do RCBOs normally have 2 flying leads - neutral and earth? Are there "old" rcbos and new types. The reason I ask is that I have bought Proteus RCBOs and they have a flying neutral wire only. I've never fitted RCBOs before and am just a bit confused. Any explanations appreciated. Bul
