High power electric motor trips the CB. That is not good. You take a high risk resetting it. Remember the DC-9 and rear toilet motor CB incident that resulted in an onboard fire. The LDR for TE flaps UP is not so great an increase on a dry/good runway. If you are at minimum fuel you still have an ALTN. It would be a bad hair day if that too was as limiting a runway as destination. Electric motors tripping CB could mean mechanical malfunction creating heat, short circuit creating sparks, stuck flaps leading to handling problems, etc. etc. Park it somewhere non-limiting and have a coffee.
