Contractor used a 20A 2 pole A/C breaker instead of 15A 2 pole A/C recommended breaker

[Cartoon1]

Hello! We have a small A/C unit that has a manufacturer recommended MOCP at 15A 2pole. Contractor installed a 20A 2 pole. I don't think this is an issue personally since the wire is sized for 20A #12 especially. Wanted to see everyone opinion on this matter, should it be changed to 15A?

Thank you

It's likely that the 15 amp MaxOCPD was not a suggestion but a requirement. It needs to be changed to a 15 to be code compliant.

So to be more precise. This is what it says on the datasheet which is possibly an error (not sure).

-Recommended Fuse/Breaker Size: 15A
-MOCP: 16A (yes it says 16, that is not an error lol)

Data sheets are often inaccurate, what does the nameplate on the AC say?

2023 NEC
Follow the manufactures instructions, 110.3(B),otherwise there might be a violation of NEC and the MFGs instructions.
Yes, check the nameplate and go with it.
If it calls for a 16 amp OCPD then you might have to use a fused disconnect or use a 15 amp CB.
15 amp may hold the starting load.
It's ok to use a 20 amp wire but must conform to the correct OCPD.
Tell the EC to make it conform to NEC.
Is he properly licensed in your state?

Thanks for reading.

If there is a fused disconnect with 15 or 16 amp fuses then you are just fine. If there is no fused disconnect and only using a breaker, then you must comply with the information on the nameplate of the unit. A 20 amp breaker would be to high if thr unit says 15 or 16. Post a picture of the nameplate if possible
