Narrative:

We were on the arrival into ZZZ approaching zzzzz intersection. The workload was just starting to increase as we were leveling for a crossing restriction and slowing for a speed restriction just ahead. Gen 1 tripped offline with the associated caution message. I immediately called for the QRH. As the first officer (first officer) started the procedure we were interrupted by a radio call that he immediately answered. At this point the procedure got rushed and I reset the generator without proper confirmation from the first officer. I reset the wrong generator switch; resulting in an inadvertent air driven generator deployment. The electrical transient also caused a flap fail with flaps at 0 degrees. We spent the next several minutes prioritizing the associated caution messages and running the applicable QRH procedures. Midway through the flap fail procedure the decision was made to divert. We were finishing that procedure while on vectors for [the] ILS. We then took several delay vectors to finish the procedure; re-check weather; brief the approach; and run normal checklists. We landed uneventfully and taxied to the gate.the event was caused by me getting in a hurry and deviating from established methods of running QRH procedures. Slow down and methodically run the QRH procedures slowly and deliberately.

Title: CRJ200 Captain reported a GEN 1 trip during arrival but during the QRH procedure GEN 2 was inadvertently reset which caused the ADG to deploy and a flap fault.

Narrative: We were on the arrival into ZZZ approaching ZZZZZ Intersection. The workload was just starting to increase as we were leveling for a crossing restriction and slowing for a speed restriction just ahead. GEN 1 tripped offline with the associated caution message. I immediately called for the QRH. As the First Officer (FO) started the procedure we were interrupted by a radio call that he immediately answered. At this point the procedure got rushed and I reset the generator without proper confirmation from the FO. I reset the wrong generator switch; resulting in an inadvertent Air Driven Generator deployment. The electrical transient also caused a flap fail with flaps at 0 degrees. We spent the next several minutes prioritizing the associated caution messages and running the applicable QRH procedures. Midway through the flap fail procedure the decision was made to divert. We were finishing that procedure while on vectors for [the] ILS. We then took several delay vectors to finish the procedure; re-check weather; brief the approach; and run normal checklists. We landed uneventfully and taxied to the gate.The event was caused by me getting in a hurry and deviating from established methods of running QRH procedures. Slow down and methodically run the QRH procedures slowly and deliberately.
