Hi all,
I’m installing a single zone mini split heat pump/AC unit on our house and have a question on the wiring. The unit calls for a 120V 20amp dedicated circuit, but the manual does not mention the need for a service disconnect near the compressor…so I’m wondering if the service disconnect is required for mini splits as it is for central AC units.
Also, if I do need the disconnect, are there boxes specifically made for these small 120 v units (I went to our local big box store and all they had were 60A/240v boxes…)?
Any help appreciated!

Yes, you need a disconnect ... and a service outlet (GFCI protected receptacle) near the condenser.
