Narrative:
Aircraft arrived for our flight with APU feeder fault annunciation and was released with APU generator inoperative. Maintenance had pulled and collared circuit breaker U-36 APU generator control circuit breaker. I checked the logbook and MEL book and we received the amended release prior to departure. Trip to ZZZ was uneventful. On the ground in ZZZ, I checked the MEL book again and asked the maintenance person who did the walkaround if the circuit breaker needed to be pulled and collared since there was no maintenance procedure for the MEL. He checked with maintenance and they sent someone out to remove the collar on the circuit breaker and note it in the logbook. I don't know if the reason the circuit breaker was pulled in the first place was to mitigate a feeder fault problem, but the APU would not be used for electrical power with the MEL. Flight from ZZZ was uneventful.

Title: AN MD80 WAS DISPATCHED IN NON COMPLIANCE WITH THE APU GENERATOR INOP PER THE MEL. CIRCUIT BREAKER FOR GENERATOR CTL PULLED AND COLLARED IN CONFLICT WITH THE MEL.
Narrative: ACFT ARRIVED FOR OUR FLT WITH APU FEEDER FAULT ANNUNCIATION AND WAS RELEASED WITH APU GENERATOR INOP. MAINT HAD PULLED AND COLLARED CIRCUIT BREAKER U-36 APU GENERATOR CTL CIRCUIT BREAKER. I CHKED THE LOGBOOK AND MEL BOOK AND WE RECEIVED THE AMENDED RELEASE PRIOR TO DEP. TRIP TO ZZZ WAS UNEVENTFUL. ON THE GND IN ZZZ, I CHKED THE MEL BOOK AGAIN AND ASKED THE MAINT PERSON WHO DID THE WALKAROUND IF THE CIRCUIT BREAKER NEEDED TO BE PULLED AND COLLARED SINCE THERE WAS NO MAINT PROC FOR THE MEL. HE CHKED WITH MAINT AND THEY SENT SOMEONE OUT TO REMOVE THE COLLAR ON THE CIRCUIT BREAKER AND NOTE IT IN THE LOGBOOK. I DON'T KNOW IF THE REASON THE CIRCUIT BREAKER WAS PULLED IN THE FIRST PLACE WAS TO MITIGATE A FEEDER FAULT PROB, BUT THE APU WOULD NOT BE USED FOR ELECTRICAL PWR WITH THE MEL. FLT FROM ZZZ WAS UNEVENTFUL.
