Hi All,
I’m designing communication racks that include IBM servers and other communication equipment.
The input power is -48vDC and the total (maximum) of watt is 29466W.
Can someone help with 2 questions:
1. What is the size of cable in need to use here (AWG wire size)?
2. What need to be the Circuit breakers Amp size?

If it’s possible please explain me how I calculation to above 2 question, I’m always know the input power (-48vDC or 220vAC) and the total watt.


Thanks,
Eran.
