3.2 - Description of cables and protective devices
• These tables should never be used instead of current standards.
Note:
• The mains current value is a typical value which depends on the source impedance. The higher the impedance, the lower the
current.
• The fuses (UL approved) are intended for installations capable of delivering 5000 A maximum at 480 V.
