How the CPCs are connected? How would you code the fuseboard?

That left side conduit looks like it is terminated through at least two entries by the look of it.

The CPCs are the metal conduits.
If there is continuity to the each point on the circuit, then no code. Otherwise C2 for lack of adequate CPCs.
The black earth wire may be the earthing conductor, but this will need confirmation.

Are the conduits joined througout the installation?? maybe they hsve used the conduits for cps
