A question to our Airbus engineers. FACs power supply in flight ?

[Black Pudding]

So a question to our Airbus engineers. Would there be any reason why we should or could switch off the FACs in flight ? or what other CB reset procedure would we do that we would inadvertently cut the power supply to a FAC or FACs ?

Marhaba.

I am not an engineer.

A reset is one thing; turning off the power (CB) is another - I have never done that.
