Wiring Of Hvac Heat Pump Electrical Installation Of AC Unit

[@fredflintstone5356]

This is exactly what I needed to know for the first half. I am doing some rough in’s for an addition to my home and putting a mini split for that room. Getting an electrician to do the rest but just want the rough in’s done good enough to pass inspection. Thank you!

[@joshuapinter]

That was seriously good. You can tell you could do this with your eyes closed. But, you didn't skip any steps so the average DIY'er could tackle it themselves, albeit taking 10 times as long. :) Thanks for taking the time to make this.

[@Dav3523]

Thanks - super helpful. We had a baseboard with a 220 30-amp breaker, but the installer used 14/2. When I checked the voltage, one wire was 121 volts, the other was 14. It's an old breaker in an old panel, but there's a new sub-panel to the side, so going to do exactly what you've done here, and use the right wire (10/2) and a 30 amp breaker for our 24k BTU heat pump.

We're having a Mitsubishi heat pump installed next week to replace our 30 year old furnace and AC. We also have an Eaton panel, so this video was exactly what I needed to know what to do. Thank you!

I just did a similar installation and it took about a whole week! The reason is that I had to make a rather complicated series of pvc pipes and 45 and 90 degree elbows to wrap around the various ins and outs of several rooms, on the foundation under the siding, taking care to rout it over and behind various other obstacles, over to the big power panel. I wanted a neat appearance, so took extra time to piece it together using many pieces, all while being eaten alive every day by hordes of mosquitoes. Then drilled into bricks around this perimeter to clamp the pvc on neatly. The interior unit caused even more problems and several weeks' work because it is an old house with plaster-on-lath walls, and I needed to repair big holes in the plaster, and attach drywall as needed. Because of lack of modern standards with wall studs (they are not evenly spaced and cannot be found with a stud-finder), it took lots of drilling holes to find any studs, and of course only one could be used to attach the mounting plate. Making the 2-1/2" hole was another difficult chore because it is not a simple matter to neatly drill plaster (it is more like brittle mortar) without it breaking loose from the lath. Another problem with the lath is that parts of it are not firmly mounted to any studs, so it is hard to cut loose wood that is just flapping around. In general, I find that any renovation job in this house requires about 4 or 5 times as much work as the same job in a normal modern house. That's why everything looks so easy in the youtube videos, most people face far easier tasks. The last job, installing the outdoor condenser unit, will surely be the hardest part, for many reasons I won't go into. Bottom line: installing this mini-split is taking MONTHS. Oh, besides the thousands of mosquitoes every day, I recently checked the thermometer outside: it was 103 degrees in the shade, but of course my work required working in direct sunlight, had to be far hotter than 103!

You have got a talent not just technical but also the skill to demonstrate, keep it up. Just improve the camera directions and the lights.

[@DWESENTERPRISE]

I just called Fuse Electric to wire my mini split ac, which is 6ft away from my breaker outside. These dudes gave me an estimate for $1041.67. Labor is showing as $850 and the rest is the parts. I can't believe how simple it is

[@PedroRodriguez-bp8pq]

i said the same thing" These electricians are wanting our bodyparts for a AC DISCONNECT. Did it myself after watching this video. I just turned off the main breaker.

[@svg001]

Must the AWG of the wire FROM the Disconnect TO the panel be exactly IDENTICAL TO (more or less) the whip AWG? (I have RovSun 12K btu, "SJOW 4x16 AGW 60 -300v"? THUS, 16 AWG to the disconnect from unit, TO 16 AWG to panel ?) ...I also intend on using Eaton 20A-60A GFCI (code req'd) disconnect box; with 10-2 Romex and 30A dpoled breaker; 1/2 pvc conduit run. Overkill? underkill? Thx! I know a lot of ques, but main ques matters, identical wiring...

[@JohnBGood-kq3ul]

Where would you even find 16 ga wire to run from disconnect to panel?

[@hozettes]

Thanks for this..you make it look easy and you included all the important details!

[@DanielRichards644]

Be honest, how many times have you slipped and sliced yourself when using a cutter to strip the insulation like that?

[@number1pappy]

Question.....im going to be installing 3 separate mini splits in my house . The 3 condensers will be sitting next to each other on the outside of my home. Do i need to have 3 separate circuits for electricity?? Meaning each mini split condenser will have a separate circuit, breaker and disconnect. I have a 200 amp breaker box with enough openings to do it however i was wondering if there was a different way of running power to them having only one breaker in the panel and then separate disconnects outside. Thanks 😊 .

[@Infidel67]

Jeez, I can't even find the correct color code Romex for 230 12 AWG like Red and Black, I know I could use red electric tape but I don't want to do that. Great Job by the way.

[@M_Rasmussen58]

Use 12/3 Romex. It comes with a red and a black. Plus white neutral and a ground

[@16hershey135]

Very nice and practical! Thank you 👍

[@artinist]

great instructions, thx

[@JapaneseJoinery]

Does the amperage of the heata pump matter? Is the switch a breaker or just an on off switch? Link to product?

[@eldenboy11]

I thought you could not put Romex in conduit? Should you strip off the jacket before putting in to make the whip?

[@conquerallelectrical]

We are permitted in Canada up to 15 ft by our local inspection authority.

Thank you for this video.

[@maggotthemadman8142]

Good install man.

[@dapinoycookingshow]

Nice video. What type of wire did you use? is it rated for outside use? I am planning to do this at home soon. Thanks

[@Smithers4]

Was wondering the same. Im thinking it doesn't have to be because it's not exposed to the elements. It goes from inside the house directly to inside the ac shut off. I was looking for a video with this exact setup as I don't want to use conduit for just a few inches of line being run.

[@theseattlegreen1871]

This man did not use outdoor weather resistant conductors. FAIL

[@willhunt3000]

should have used THHN/THWN inside the whip

[@dg-hughes]

I'd like to get a heat pump but my panel is old it has glass fuses not breakers.

[@maggotthemadman8142]

Still can be done, it's just a little bit more pricey. Nice to see a fellow red sander as well.

[@Weasel_NM575]

Here in New Mexico you’re not allowed to run romex in flex pvc or emt in wet or damp locations

[@zivaschan]

and some places has to be scheduled 80 not 40. also did i hear him correctly in the beginning of the video he said he was using 12 gauge even after reading the MCA on the nameplate indicates #10?

[@maggotthemadman8142]

@@zivaschan You only need 12/2 for 15 amp breakers. 10/2 is a waste of money, that's more for 30 amp breakers.

[@maggotthemadman8142]

12/2 for 20 amp breakers as well, and mini splits are always double pole.

[@JohnBGood-kq3ul]

@@maggotthemadman8142 Some smaller ones are 115 v., so only need single pole.

Awesome. Thx

[@nickfitzgerald3673]

Great video, thanks homie!

[@BD-ly7xj]

I've have never seen an impact gun used on a breaker. Lol

[@arthurcarlson6463]

What type of wire did you use? Indoor?

[@conquerallelectrical]

I have reflected that in the description of the video for you as I have been getting a few questions on it. Hope this helps. Have a great day.

[@zivaschan]

i thought if the MCA on nameplate states 10 gauge even if if is a 15 amp breaker, shouldn’t the minimum be 10 gauge?

[@zivaschan]

i hope this house doesn’t burn down

[@zivaschan]

also as i watch the video, i am not sure if local codes anywhere (in USA at least as far as I know) allow for romex inside conduits, even in short lengths, has to be stranded THHN in the whip, which from my understanding some local codes does not allow for schedule 40 and only 80 if it is near the wet ground even if it is liquid tight.

[@chrism81804]

@@zivaschan What are you talking about? MCA =/= wire gauge.

[@zivaschan]

@@chrism81804 this is all assuming it is a 75°F temp vs 60°F calculation....

[@zivaschan]

@@chrism81804 To sum it all up - The MCA is the minimum wire size needed to guarantee that the wiring will not overheat under all operating conditions for the life of the product. The MOP is the maximum allowable circuit breaker size that will properly disconnect power to the equipment under any anticipated fault condition. Minimum circuit ampacity (MCA) and maximum overcurrent protection (MOP) are necessary to correctly connect field wired equipment . As their names indicate, the ratings will tell you the minimum wire size and maximum circuit breaker size allowed for the equipment. Higher currents have led to a greater awareness of the risks of overcurrent and fires. The system of MCA and MOP was developed to reduce that fire risk. Supply wiring must be rated to carry at least the amps shown as MCA. By comparison the overcurrent protection device (either a breaker or fuses) must be sized to prevent the unit from drawing more current than the MOP. Minimum Current Ampacity (MCA) MCA = 1.25 x [Motor Rated Current + Heater Current] www.electricalservicetechnician.com/how-we-calculate-mca-and-mop/

[@gilgreen4297]

how do you call the red wire you used? does Homed Depot carry them?

[@Smithers4]

He said its 12 gauge (12awg) most popular brand is romex and its 2 wires plus ground so 12/2 wire is what he used. But you may need 10AWG which is actually thicker than 12 depending on your amperage needs which would be 10/2 for use up to 30amp.

[@adriancaldera8756]

Im doing a 220v and my mini split is asking for awg 14 which amp breaker do i need

[@Smithers4]

@@adriancaldera8756 The mini-split has to specify the max and min size breaker. Usually on a sticker on the outside unit. I usually go with the max breaker number. 14 AWG is good for 15amp breaker max and thats already pretty small for a mini split so I would assume thats what your looking for. But you have to check with your unit or paperwork to be sure. Also go with UF ware not the NM-B as NM-B is not rated for outdoor use. There are others you could get aside from UF but that is most common at homedepot/lowes.

[@zivaschan]

@@Smithers4i thought you cant go any lower on the MCA on the nameplate, as in if it states 10 gauge minimum, you cant use 12. (except depending on calculations you can use thinner gauge copper THHN than the MCA)….?

[@Smithers4]

​@@zivaschan I agree that you cant use a smaller wire gauge than the MCA if thats what youre asking.
