    I was just curious what were the old Irish 3-phase colours, before the introduction of the current harmonised European Blue (N), Brown (L1), Black (L2), Grey (L3).

    I'm pretty sure I came across an interim colour code that used blue as neutral and brown as a phase, but wasn't the current CENELEC standard for the other two phases.

    Brown, Red & Yellow ?

    Neutral:Blue
    L1:Brown
    L2:Red
    L3:Yellow

    Before they were changed to this they were as Pieface said

    Neutral:Black
    L1:Red
    L2:Yellow
    L3:Blue

    51fun, you are correct. The first phase colours you show did not last for long for some reason.

    I suppose that they had to change the three phase colours when they implemented the harmonised European colours for single phase, quite a long time before the UK did.

    It'd have been very confusing if blue was a phase in 3phase SMS them neutral on single phase in the same installation!

    The brown, black & grey phase colours were kinda the least worst option as they clashed with the fewest European systems.

    Wasn't it the case that when the new standards came in that they only specified that L1=Brown, N=Blue, PE=Green/yellow and it didn't matter what L2 and L3 were as long as they weren't blue or g/y?

    Ah come on, they're not actual colours, they are things my OH says are colours with great conviction and no room for discussion as I'm always wrong!! :D

    What's next? Phase colours are going to be "autumn", "summer sky" and "burnt charcoal"??? :D

    With some sparky's in this country you might often end up with "Burnt" phase colours:D
