Replacing mini-splits electrical question

[1776]

OK, I’ve got two old mini splits I’m looking at replacing. The ones I have are 220v, but it seems like most of the newer ones in the BTU range I need are 110. The breakers for the circuit are just standard 15A breakers with the handles tied. Near each mini split there’s a fuse box like this

Am I completely ****ing retarded or could I run the 110V units by just capping off one of the hot leads in this box and using the other?

Short answer no.

Your black 240 service box appears designed (and prolly wired) with a black 120 (hot wire), a red 120 (hot wire) and a uncoated wire for earth ground

I suspect any new 120 unit needs a black 120 (hot wire) which you have, a WHITE (neutral wire) sometimes referred to as the return wire that you prolly don’t have, and uncoated wire for earth ground that you have

You can turn the red hot wire into a white neutral wire and call it a day, just wrap some white electrical tape around each end and move it from the breaker to the neutral bar in your panel

Exactly this!

The box pictured is a service disconnect. Not a fuse box.

I always say: You've got to have the right tools to do anything!
Where is your multimeter?
And why are you changing this disconnect box? As CTS Tactical said, that box is just to cut power off to the heat-pump so the tech can service it!
New Mini-Split will need also a communicating wire from the head to the heat-pump (compressor unit).
