Andy:

As far as I'm aware here in Ireland 2-black cores wouldn't be at all acceptable, particularly in an industrial setting. We like to keep things properly polarised where possible. 2 core single phase cable MUST be blue (neutral) and brown (phase L1) in all cables fixed or otherwise.

A number of years ago the use of black cable for neutral was banned in all new installations or extensions to old installations. To allow black to be reintroduced as a phase colour in the new harmonised 3-phase coding system.

Heavy industrial cable is a different "kettle of fish" completely. You're talking BIG stuff .. this is a LV cable and should comply with European LV rules.. which i would have thought included colour codes.
