Hi

I am a bit unclear on one aspect of designing the system. Firstly I have a dc power suplly which produce 200V @ maximum 200A (40kW). The DC power supply unit needs 3 phase 415V input. So what is the maximum fuse should I for 3 phase AC input? Also what is the maximum current rating cable should I use as well?
