It used to be OK in general aviation to reset a breaker once. This was because on older planes the electrical systems were not particularly sophisticated and might experience breaker-popping surges in routine operations.

121/135 generally have specific rules, typically PIC discretion if the equipment is safety critical.

But given the relatively recent hull losses of two very modern heavy airliners due to apparent cockpit electrical fires I would be very reluctant to tempt fate by resetting a breaker.
