Can some please tell me the correct way to rate a low voltage switch board/panel in accordance to IEC 60439-1.
I have seen the Icw used but now I am told to use the term Icc, (page 43 of IEC 60439-1). I do not think this is correct; I would have liked to use the Icw & the Ics of the main breaker.
In 99.9% of the time I will NOT know the potential fault current at the input terminals of the panel.
