So WHY is it made with G/Y, Blue and Black if there is nowhere you can use it? Just where CAN you use it with those colours?
NYM-J does not comply with any British Standard. (It is a VDE cable.) It's not suitable for BS7671 installations.
That said any of the NYM-J I have used has been brown/blue/green & yellow in 3-core.
However, the colours you have mentioned (if indeed it is produced with those) could be used on a single phase final circuit in the south of Ireland (to ET101 Wiring Rules) fed from a three-phase DB if the circuit is on phase L2.
