if you have to fit an addtional motor to an exsisting installation...what size droppers from the main busbar to the fuse holder and what size cable from the soft starter to the motor and why?

motor 400 volt...200 kw (365 amps) with a soft starter which requires 700 amp semi conductor fuses.
main supply 1000 kva transformer feeding the main control panel.
the panel where the motor will run has a 1200 amp main switch rated at 25/35 ka...just to put a spenner in the works the transformer will be increased in size to a 2000 kva at some stage not finalised yet.
the motor will be 20 metres away from the control panel.
cables will be in paralel and touching if 2 or more are selected.
ambient temp. 55 dgrees C.
motor is connected in delta...400 volts or star if 660 is required.
last but not least is a COC required if it forms part of a machine?
