Hello again. Are you looking to continue here, with the new topic?
If you can give me the brand and model of the mini split, I'll look up the specs.
While I was waiting for your reply, I took a phone call from another customer. Just wrapped that up. Looking at your screenshots now.
Screenshot 4 shows the electrical specs. I don't see 120 volts listed for any of the various model numbers.
It shows a draw of 9 amps at 208 to 230 volts. I thought 120 volts, 8 or 9 amps sounded pretty small for a substantial cooling unit.
So, you DO need a double pole circuit. But it wouldn't need to be a double pole 30 amp, like a standard outdoor air conditioner. You only need a double pole 20 amp circuit. Technically, you could install a breaker as small as 15 amps, and #14 wire. But I don't often use 15 amp circuits for this type of load. If you go with a double pole 20 amp breaker, you need #12 wire.
You read my mind. I was just looking to see how many conductors you need. I have in the past seen these units need multiple hot wires, AND a neutral. I don't think yours does, but if you ran 3 conductors plus ground, you'd have an extra wire there if it ends up being needed.
If it is a panel with breakers, and you have the space for the double pole 20, it should be fine.
The length is not a problem. Any outside wire should be in conduit, and should not be Romex type wire. If you need to splice the Romex to individual stranded conductors, just use a junction box to do that. The outdoor unit WILL need a disconnect, unless the breaker you are feeding it from is within sight of the unit and not more than 50 feet away. In consideration of any service technicians that may work on it in the future, I would suggest putting a disconnect right at the unit.
Yes, it would be ideal to penetrate an outside wall with your wire, and bring it right into the back of the disconnect. That way, you won't even need to concern yourself with any individual stranded conductors or junction boxes.
I usually go to church on Wednesday evenings. But my kids have been so loaded down with homework lately that making it to church is iffy. If I have to stay home to help with homework, I'll be logged in here. If I make it to church, I'll be able to work with you before and after.
Happy to help, and thankful for your friendliness. Looking forward to wrapping this up, and helping with whatever you tackle next, if you need me.
Yes, it all sounds good. From the disconnect to the unit, you can use a flexible, outdoor rated conduit. We call it "Sealtite". That's kind of a generic name, like "Romex". There are 2 types of liquidtite flexible conduit. One has a metal core in it, and one doesn't. The one with the metal core is better, but costs more. It will hold up longer. The one without the metal core seems a little cheesy to me, to be honest.
Sounds good. I'll keep an eye on the site as much as possible.
Hey there. If the wire is encased in some type of protective (weather proof) conduit, it doesn't have to be outdoor rated wire. If you use the flexible liquid tight (gray) tubing, you can put any type of wire you want in it. One manufacturer is Carlon. Would you like me to post a product link or page for you?
Without seeing it, it's difficult to know for sure. But based on your description, it sounds fine. If you want to post some pictures I would be happy to look them over.
Thank you for posting the diagram. It looks great. I see no issues with proceeding as drawn. There are no Code issues here.
Sounds good. I'll keep an eye out for you.
Should be fine. Disconnect amperage ratings are considered "up to" the number. Anything lower is a non-issue.
Yes, it appears the panel that has the breaker for the pool takes Square D "QO" series breakers, which are often seen in commercial applications. It's not uncommon to see them in residential applications though. They are a very good model of breaker, so I do like finding them in use in homes. The Lowe's page shows a QO series Square D breaker. Can you post a pic of the breaker you have that doesn't fit the panel?
I see the issue. The last link you posted is for Square D's "Homeline" series of equipment. That is a residential rated breaker, and it most likely wouldn't be used anywhere other than in a residential application. In my opinion, the "QO" panel you have is better... a higher grade of equipment. I would just return the Homeline breaker, and get a QO.
