First, kudos to Aeoluskratos for a sincere and nicely done first post.
Second, I don’t wish to rehash the subject of fuse directionality, which has been debated ad nauseam in this thread. But I want to correct a misstatement of fact:
That can be easily seen on an oscilloscope, where the vertical axis of the graph that is displayed corresponds to voltage and the horizontal axis corresponds to time. AC will look like a close approximation of a sine wave, swinging both positively and negatively, above and below zero volts.

Geoffkait 5-10-2017Both the voltage and the current alternate in AC. That follows from the fact that per Ohm’s Law, which applies to resistive loads, voltage and current are directly proportional to each other. (And for a capacitive load current is proportional to the rate of change of voltage, and vice versa for an inductive load, and all of those quantities also alternate in the case of AC).
It’s not really "electricity" that is alternating, it’s the current that’s alternating. The voltage is not alternating. Otherwise they’d call it AV.
