Assuming a load without significant inductance or capacitance am I correct in thinking the fuse should be about 1.3 times the expected operating current then use the next available sized fuse above this?
Additionally, at what point is the fuse size too large? What the general rule here? Is it at twice the operating current or 3, 4, 5 times?
I assume this depends on whether it’s being used to protect against short circuit or overload. How would you decided what to use based on protecting from:
