Narrative:

Shortly after taxiing for departure, we were advised by the cabin crew that we had arcing, sparks, and smoke about halfway back the airplane on the left side. We executed the 'electrical fire' checklist, requested assistance from the emergency fire unit and returned quickly to the gate and deplaned the passengers. Fortunately, the appropriate circuit breaker popped and the fire stopped. Since the incident, the FAA has made at least 2 inquiries as to who summoned the emergency equipment. I did. It seems simple to me, if you have a fire it's a good idea to call a fire truck. Hopefully, they will eventually be able to figure it out.
