Connection a mini split to a 50 amp RV outlet
I want to knock down the temp in my garage and was wondering if I can tap the 50 amp RV outlet in my garage to run a mini split 220 unit?
Plenty powerful circuit, I'd do it, but where you going to put the smaller minisplit breaker?0
no, not without wiring and protecting it for one or the other.0
That’s one honking huge garage if you need a 50 mini split system. Might want to check with an electrician. If you burn the joint down, you don’t want to be arguing with the insurance adjusterGary Wilson

Do you not have an electrical panel in the garage?
You probably cannot use the plug for both. If you want to repurpose that circuit and just use it for the mini split, that would be doable. You would need to change the breaker so it is rated for the mini split."If you can't explain it simply, you don't understand it well enough"
You would need to properly fuse the for the line being used and properly fuse for the load or equipment . Surge protector is a good idea .I have enough experience to know , that I dont know it all0
The mini split will be just a few feet from the existing outlet. I can put the air handler just above the outlet and the compressor unit directly on the other side of the wall.0
The concern is overcurrent protection of the feeders between the existing circuit and the mini split. Me, I'd remove the recept. & replace the 50 amp breaker that's feeding the RV circuit with whatever's called for on the mini split (25A?), but that would mean you'd loose the capability of plugging in to shore power. If you wanted to keep the recept, add a small subpanel.
Pay attention to bonding and grounding—they're distinct entities; & not always intuitive.1
I live in Surprise Arizona and it looks like I’ll need to find a Electrican who can do the sub panel hard wiring. Anyone local to Phoenix interested?0
shows you what I know.... it is connect to a two switch 50 amp breaker so I thought it was 220 but I am clueless on this stuff. Everyone’s help is much appreciated as this is my first rodeo on this. I’ll send a picture.0
That's a NEMA 14-50R & is indeed 240 volts, although it has a neutral for 120 volt loads as well.
Set a small (4 circuit) panelboard, use two spaces to refeed that recept & the other to feed the mini split with an appropriately sized circuit. You may run in to trouble using both the RV recept and the mini split at the same time (tripping the feeder breaker in the house), but I think that's not going to occur too often.0
Sere discussion about load calculations and breakers being to protect from faults, not overloads from improper design.0
Add info ....Check your voltage , critical to keep it with in middle the range of the unit working voltage . If not a boost buck transformer would be a good idea .. Just installed a system in a cabin with 253V needed one to buck it down to 217V .....I have enough experience to know , that I dont know it all0
IIWM, I would remove the outlet, install a metal box extension on the existing.
Then 1" pipe up to new panel from extension, splice all 4 wires in old box and run them up to feed new CB panel. Then in same pipe run new 4 wires down to outlet installed on extension box.
Run pipe from CB box out to outside unit.0
