Afternoon, 

I am currently reviewing a design that has 2 X low voltage DC 200KW circuits (185mm Ho7 Singles) run ducted underground at a depth of 600mm along with a couple of ducted 32A single phase circuits (25mm Ho7) (Both Band II circuits) the separation distance between all circuits underground is 0.25m is this ok in terms of AC / DC segregation? the AC circuit is a standard 230V circuit and the DC circuit can have a voltage of up to 1000V (EV Charger) 

using TABLE A444.1 – Summary of minimum separation distances where the specification and/or the intended application of the information technology cable is not available, shows a 200mm separation distance. but I wanted to make sure there was nothing I was missing, 

Thank you in advance
