Wylex NS11 Consumer unit

[philipbg]

Customer has a Wylex NS11 board with NSC cartridge fuses.
They want some work doing, so now need RCD protection.
The NHXB RCBO have always been a good fit for NSB MCB, doe's anyone know
if they work for the NSC.

The last time I looked at upgrading a Wylex board that had NSC cartridge fuses, to fit Wylex RCBOs, the issue was the internal layout of busbars etc. meant they physically weren't going to fit. But that was a dual supply board (for a property that included storage heaters), which also seemed to have a couple of half-module gaps in places (with half module blanks).
