Rating of Bus bar

08/03/2009 9:54 AM

Sir ,

I want to know that how can we calculate the current rating of Aluminium and Copper Electrical grade bus bars. right now i am taking 0.8 as a dividing factor for calculating the bus bar current rating (width X thickness / 0.8 )

Is it the correct way ? if not please tell me the right way.

If it gets too hot, it's too small.
