Narrative:

Smoke was observed in cockpit. We shut down the engines and evacked the aircraft. Electric wiring had shorted out and started to burn caused by insulation rubbing on the wall of the upper panel. This insulation had worn through causing it to short itself out. No injuries or problems were observed.
