• I = 128 A + 25 % = 128 x 1.25 = 160 A
• For AWG2/0, the maximum current is 175 A, which is sufficient => use AWG2/0
• Install the prescribed maximum fuse (150 A) on each cable
• Parallel supply cable (2 x 3 phases + 2 PE - configuration (2)):
• I = (128 A + 25%)/2 = (128 x 1.25)/2 = 80 A
• For a AWG4, the maximum current is 85 A x 0.8 = 68 A, which is insufficient. For an
AWG3, the maximum current is 100 x 0.8 = 80 A. So 2 parallel cables of 3 x AWG3 + 2
x AWG8 are sufficient.
• Install 80 A fuses on each cable.
