Once you have the run capacitor out of the compressor unit, being careful of the terminals, rotate the run capacitor until you can see its label. They used 10 gauge and 30 amp breaker. They are at the bottom of the table and will show what I use and what the inspectors go by. Now something just came up. I believe he's an electrician. From some discussions I've seen online it looks like people are using the Interlockit product.
This might not apply directly to air conditioners but I think the code writer's reasoning is the same. So if one wants to wire up just the essential circuits heat, light, etc , there would be 2 terminals on the individual breaker: one for normal power and one for generator. The length of line set, indoor unit valve to 9 ± 1 ºF superheat, then check subcooling. If the job works, you're good. I also go by the manufacturers requirements unless they clash with the inspector who has final say.
Or some home inspector flags it. Actually, 12 would also meet it. Move to the outside compressor unit. If not, then typically just the disconnect box on the exterior is changed. It didn't matter what the paperwork from the manufacturer stated. Could low r22 cause reduced reading? The label will tell you.
The compressor unit will try to start again after a short time. I use the Square D dummy breaker in a rain proof box. Unless the wiring is too small, deteriorated, etc. I'll leave the existing wiring for now. This is a common confusion. During a high stress power cut, it's easy enough to forget a step or two in the procedure. I finally got fed up enough and being new to the area was willing to be the one who pulled his plug by documenting it and making the complaint.
Hay bailing sounds great and of course he will never forget, be sick, not there and someone else needs to do it or whatever. Although marked on the bottom in the metal, it can be difficult to consult the bottom once you start connecting wires to terminals. Unless you have a very good reason and can show the inspector where he is mistaken, it is best to just do as they say. Actually, 12 would also meet it. The fan motor on top of the compressor unit should start turning immediately, if it is not defective. The reading have been stable last 2-3 summers. And gfretw has weighed in on the issue.
This label will define what you must buy as a run capacitor replacement. It further states that a 40 amp breaker is the max allowed, which is what he has. You can add a subpanel and move some of the loads to it. This is a common confusion. In some places they actually have to use a stamp with their name and number for the department which can be seen inside breaker panel doors. Overcurrent protection can be 175% of the value shown in the chart. If you ever get on their bad side, they will really look over your work and try to find a reason to make you redo something.
If you read any voltage at all, do not proceed. Years ago, I trained in martial arts and got knocked on my butt numerous times but I learned from it to the point that my instructors couldn't get through my coverup and I could block kicks and punches. You might have no choice but to pay someone to repair your unit. It was a 3ø unit that called for a 15 amp breaker. I did not even know those interlocks existed.
Far more likely they apply the correct section of Code for the purpose at hand. But it would be a bitch to buy it, install it and have it rejected. Understand that the temperature rating of the insulation also determines the amp carrying specification of the wiring for both copper and aluminum. It's easier to just connect new wires to new breakers rather than install boxes, deal with splices, etc. Of course if you use 8 gauge where a minimum of 12 gauge or 10 gauge is required, it passes because it meets code. I strongly suspect if that were done it would be found that the installation under discussion is compliant there as well. I don't argue with the inspectors, you can if you wish.
I may actually know someone there. Purge or pump-down excessive charge. Now something just came up. It has run without a problem for 10 years in three different locations. How to install a new run capacitor: Once you have a new run capacitor, mark the outside of the capacitor with a marker of some kind such that you know the definition of each terminal: herm, com and fan. Please let me know if anyone finds a lower price anywhere! Never replace parts unless you are sure or think you are sure they are bad or defective. So, he goes on thinking that 8 gauge is what is required for it to pass.
