R.C.B.O. Preference.

Zoomup
Q. Why do I prefer the modern Niglon R.C.B.O. design over the modern Lewden R.C.B.O. design for domestic consumer units?

    Re Colin Haggett    Concur.  Why would you NOT prefer a Double Pole RCBO particularly with a TT supply through 2 overhead cables?  With or without an SPD the overvoltage (from the lightning strike) is just as likely to come down the neutral line as the phase line..

    Are R.C.B.O.s concerned with lightning strikes and their effects, or is that just the job of S.P.D.s? The neutral is earthed though, at the source of supply.
