I am about to install a backup generator about 40m away from my house. There is no question what cables to run for the AC current (which will be 230V 50Hz up to 30A) — doubled 10AWG (6mm2) to keep resistance at acceptable levels at such distance.
But I do want to run a data cable along the AC cables: this will be needed for remote control of the generator, surveillance camera and what not. Obviously it would struggle to perform side by side with the AC cables so it will need to be shielded (STP, not UTP).
Setting aside any regulations/standards that would prohibit doing this, will STP cable work? Where would be the best place for it in the pack — in the middle (A), at the edge (B), or elsehow?:
