Aircraft; Human Factors; Procedure
Upon applying takeoff power the takeoff warning horn sounded and I rejected the takeoff and taxied clear of the runway. The speed was under 20kts at the time the reject was accomplished and no reverse or braking was required. After starting the engines and selecting flaps to 5 degrees the flap circuit breaker had tripped without us realizing it. After we completed deicing the aircraft craft the First officer requested the information from ops for the fluid used and other required information. They responded saying they would have to get back to us with that information since the radio in the truck was not working and they were relaying the info. While we were running the taxi checklist ops came back with the information and interrupted the checklist while the first officer read Flap -Verify- 5 selected and indicating. Neither the first officer nor myself looked at the actual indication of the flaps after the interruption. This lead to an improper configuration for takeoff which sounded the takeoff warning horn. Takeoff was rejected and we taxied clear of the runway; once clear we looked at all items that would cause the horn to sound and found that the flaps were indicating 0 degrees yet the flap lever was at 5 degrees. I then looked to see if the circuit breaker had tripped and it had. I called dispatch and was transferred to maintenance control and advised them of the events. We decided to return to the gate and deplane until maintenance could look at the aircraft. We should have run the taxi checklist over again from the beginning instead of continuing from the last item when the interruption occurred.
Flaps failed to travel to the position they were set to. Mismatch indication between the flap setting and indicator. Electrical problem; the breaker popped. Rejected takeoff; maintenance was called and the breaker was reset. Ops checked good. We were redispatched.
Dash-8 flight crew reported rejecting a takeoff due to the takeoff warning horn sounding. Once clear of the runway; the crew recognized that the flaps were not in the selected position. A circuit breaker was found popped which prevented the flap movement.
