Hi,

I am designing an industrial Power Distribution Board, and what is the relationship between power cable length and short circuit current? It seems there is a minimum cable length required to limit the short circuit current within rated incoming current.

I need advices.

Thanks!

Here is a guide I found, It show a table of cable lengths with cross sectional area.
* "Minimum levels of Short Circuit("")":http://www.electrical-installation.org/enwiki/Calculation_of_minimum_levels_of_short-circuit_current

Hope this helps,
Kevin
