This is another prime example of "inrush" vs. average starting current and what will blow the fuse and what will not.


In this screen capture we can see that the starter drew slightly over 640A during the peak inrush. It should be noted that this 4 cylinder diesel motor has been started in excess of 1000 times with a 300A ANL.


When sizing for starting loads always use the largest fuse you can for the wire, so as to eliminate any chance of "nuisance trips".
