I am going to be honest here.
I have used a fan to keep some breakers from tripping.
I had a night time service call to a long existing grocery store, they had lost a couple of lighting circuits. Well I found the circuits had tripped but many of the other breakers in the panel where also warm.
A little checking with the amprobe showed all 20 amp lighting circuits to have at least 18 amps of load with a few over 20 amps.
So....out came the fan to keep the circuits on that night and the next day a crew was there breaking up the circuits.
Of course I did not leave any live parts exposed.
