why do proteus rcbo's not have an earth wire when all the others i think do ?:30:

 

[MarkieSparkie]

Proteus have managed to miniaturise the mechanics and the conventional toroid transformer without compromising sensitivity. Therefore they don't require the usual RCBO electronics, usually needed to achive the functional sensitivity. A benefit of the lack of electronics means a functional earth reference is not required either.

really i'm impressed as usually proteus is a bit er er em not good
