While preflighting the cockpit; I noticed a wiring bundle had migrated out of the captain's seat control unit. All of the wires had been pinched and multiple portions of the wiring insulation had eroded; exposing bare wire. After contacting [Maintenance Control]; local maintenance arrived; and after communicating my concerns with the bare wires; the mechanic tucked the wires back into the unit without any repair whatsoever. This left the opportunity for an electrical short to occur in the captain's seat while the seat motors were operating. I explained to the mechanic that I could not accept the aircraft with the wiring in that condition unless power to the seat was deactivated and a deferral applied. He accepted my decision without argument and called in the local Airbus rep to assess repairs; grounding the aircraft.
A321 Captain reported discovering bare wiring on the Captain's seat control; which resulted in maintenance cancelling the flight.
