Wife Code for black pvc with separate earth run to socket?

[Lucien Nunes]

There is no requirement that the cpc be integral to the cable, so no code

Although there is a requirement for a separately run CPC to be of a minimum CSA (for mechanical strength) which this might not be. I have a mental block on what the minimum size is though!

The cable from the board is a black pvc 2 core cable

There is another possibility that hasn't been mentioned. There is a popular 2-core cable with red and black cores in a black PVC sheath that is still made and used, for vehicle and marine DC wiring. The giveaway would be that it is fine-stranded; it might or might not be tinned. It is made in a wide range of sizes that don't all correspond to familiar CSA's, e.g.14/0.30 is 1.0mm² but the equally popular 28/0.30 is 2.0mm². I have seen it used for domestic wiring with a separate earth, but it is not made to the relevant standards nor rated for 300/500V.

OP: Is the separate earth bare or insulated? (historically, when a separate earth was run with TRS, it was usually bare tinned copper).
How many strands have the conductors? Pics please!

If the cpc is bare, then the minimum is 10mm2, other than that as a cpc it's just the adiabatic needs, unless it's buried and for earthing rather than cpc which is 2.5mm2 with mechanical protection and sheathed.

Or 4mm2 if sheathed but no mechanical protection.

I thought the minimum separate cpc size was 4mm when not mechanically protected ?

Wife code and black pvc? Sounds interesting.
