How Can We Calculate The Busbar Short Circuit Current?
What will be the Short circuit current for 25x3 sqmm copper Busbar
1 Answer - Sort by: Date | Rating
It is generally dependant on heat and the duration the short circuit would last.
300 degrees celsius is a generalisation as the allowable rise in temperature for a short circuit.
I calculate the current rating (not short circuit rating to be approximately 116A
If that were to withstand a short at 8kA short for 3.6 seconds (roughly)
i.e. It would heat up by 60 degrees C every second
