lol!
AFAIK in Austria the phases are just the other way round:
L1 black, L2 brown, L3 grey?.
However, all cables I've seen at the store still have L1 black, L2 brown and L3 black, L1 IIRC being the black one located between blue and gn/ye in a round cable. A recent 3ph CEE plug I just took apart was labeled as follows: R1 S2 T3.

Looks like they're covering all bases there by combining numbered phases with the old Continental RST labeling.

Thanks for the Irish colors. I'll forward them to Scott to add to the list. What was used under the old system? Was it the standard British phase colors?

The standing Irish colours are as follows:

Earth - Green & Yellow striped.
Neutral: Blue
L1 : Brown
L2 : Red (Cenelec system will be black)
L3 : Yellow (Cenelec system will be grey)

Cable sheath is normally light grey.

As part of a Europe-wide CENELEC harmonisation and the phases are :

Earth: Green/Yellow
Neutral: Blue
Phases: Brown (L1) Black (L2) Grey (L3) (First Phase will be Brown)

This has just been approved and will phase in over the comming years as yet is not the norm.

Old domestic wiring would have been the same as the UK [Green (E), Black (N), Red (L1) ] 3 phase was extremely rare in domestic installations and I'm not 100% familar with what was the industrial norm in the past.

shows the Irish and UK core colours compared

Core Colours: (Excludes Earth Green&Yellow striped)
UK:
2 core - Black and Red
3 core - Red, Yellow and Blue
4 core - Red, Yellow, Blue and Black
Ireland:
2 core - Brown and Blue
3 core - Brown, Blue and Red
4 core - Brown, Blue, Red and Yellow

Thanks.

I guess that when Ireland adopted the new standard it made sense to keep the red and yellow colors from the old British system and jusr replace the blue with brown, albeit with the phase order changed.

and to stick in a blue neutral!
