Historical Wiring.

Zoomup

The old days where house main earthing leads were green 6.0mm2. Ring "mains" were wired in 2.5mm2 T&E with 1.0mm2 earth continuity conductors. And the use of plastic oval conduit in plaster was common.

Is this compliant? Please see picture.

    Then our three phases all became Brown, Black, Blue

    Eh? I thought they went from red/yellow/blue to brown/black/GREY with blue for N.

    Most of Europe used various combinations of brown and black for line (they'd had brown in flexes for years too) - by and large they didn't bother much about preserving phase rotation in fixed wiring - just swap a couple of wires around at the load if it turned the wrong way (thus having two lines the same colour made a certain amount of sense).

    Having a distinct colour for L3 was, I'm told, a UK suggestion - and the only colours off the standard list not already used by somewhere in Europe for something else was grey and pink.

    Sorry Andy, my bad, a typo I`m afraid. Yep Brown Black Grey, a combination of the worserest colours in my view. Nice bright sparkly healthy colours for an N I would prefer (Red, Yellow, Blue are good uns) , duller types for N , and green/yellow for earth would all do me and, I think, within the K I S S range of things. 

    If no colour coding existed before today then which colours might be most popular folks?

    Perhaps a new thread with a Poll?
