Section IX – Technical data
112 Quincy Vacuum Pump-QSV Series

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 2 PE - configuration (2)):

I = (128 A + 25%)/2 = (128 x 1.25)/2 = 80 A

For an 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.
