Hi, I'm trying to find out the cable size I need to wire my 1650kva generator total amps per phase 2300. Total run of cable will be 30m
The Nation Electrical Code book, which governs the craftmanship/ installation of electrical work in the USA is one of the best resource journals to gather your information. I do not have one here in front of me at this work station, otherwise I would have given you the cable size you will require for your installation. You can go to a commercial wholesaller of electrical materials and the shop engineer can help calculate your needs.
Good Luck,

Ken,
6-600 mcm Cu. (75 c. rated), cable will handle the load,
but with a 30 M. initial run, voltage drop may be a factor
in a low voltage, (under 600V.), system if your secondary
distribution
runs are lengthy.
What voltage?
How long are your secondary feeders?
If this turns out to be a factor, you might find that
you can save overall by beefing up the initial feeder
rather than being forced to beef up the secondaries.
