Do you prefer the side by side connections to the front & back?
Well done Andrew, you sussed it. The Lewden range includes terminals that are not tester friendly. You have to remove the front cable to get the the rear terminal to check its tightness. The side by side Niglon design is easier to check and requires no conductor removal.
The jury is still out as to whether Type A/C's are redundant or not. I reckon there is still a place for them, given that the evidence for an exclusive Type A-only approach is not conclusive.
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.

Lost me here, am fitting DP RCBOs and it’s nothing to do with lightning but has more to do with TT supply’s with upfront time delay RCD.
