Ampacity Size of PE
< 200 A 4 AWG
< 225 A 2 AWG
< 400 A 1/0 AWG
< 500 A 1/0 AWG
< 800 A 2/0 AWG
< 1000 A 3/0 AWG
Note: The above table has been prepared for user convenience. Only the latest editions of
the UL standard and its amendment(s) are to be considered as the official documents.
Always check the voltage drop over the cable (less than 5 % of the nominal voltage is
recommended).
Example of supply cable calculation
I
Package
= 128 A, maximum ambient temperature is 30 °C, maximum fuse = 200 A
• Single supply cables (3 phases + PE):
•
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
• So use a cable of 3 x AWG2/0 + AWG4
• Parallel supply cable 2 x (3 phases + PE):
• I = (128 A + 25 %)/2 = (128 x 1.25)/2 = 80 A
• For AWG4, the maximum current is 85 A, which is sufficient => use AWG4
• So use a cable of 2x (3 x AWG4 + AWG8)
