Yes.

But you should put a warning sticker on your CU(s)

Which has always seemed a little superfluous in domestic premises with
single phase supplies.

Red - Brown Black - Blue

There's no mistaking which is live or neutral in either case.

Slight possibility of confusion when 3&E is used; Red, Blue,
Yellow, or Black, Grey, Brown - all of which can be lives.


If an electrician can't handle working with the common standard
cables, where does the fault really lie? As said the note on domestic
CUs is senseless.

Is everyone who works on domestic electrics an electrician?
