As far as the panel specs, all I could find was what seemed to be info on the panel cover. I might need to remove the panel cover for more details (tomorrow pictures).
Hrm, yeah, most panels have a few more details than that (like what types of breakers are allowed, etc...)
There is an external fuse at each of the outside A/C units (2X) - each has a single fuse in external box. Another cutoff? Not 100% sure...Nothing at the meter base.
Yeah, those are just disconnects for when technicians work on them. Probably also where they have fuses which I think are there to protect the motor windings. You have to size breakers pretty big on motors to keep them from blowing when the motor starts up (surge current) so they generally have something else in the circuit for over current protection.
Additional details:
Surface garage install - no wet or insulation.
4600 sq ft house
30amp dryer unused (have gas)
The load calculator is a bit over my head....
Learning as I go. Thanks for the instruction!
Do you have any other devices other than the gas dryer that are out of service (i.e. gas?). I am in the same boat. All gas oven/range and gas dryer. I am not sure how NEC considers outlets and breakers that are installed but not in use. I personally would not count them against your load calcs, but I could see some hard inspector wanting the receptacle removed and blanked over so it would not be easy to just have a future homeowner plug into them.
Do you have two ovens? Or one oven and one range separate?
So some notes on your pictures:
I would definitely work on a load calculation for your house. You have a pretty big house with some extra stuff in it (dual AC units, dual ovens, etc...) and so you are likely not too far from the cusp of needing to have gone to a 320/400a electrical service. I suspect you have some headroom for car charging, but I would calculate it.
What is your Authority Having Jurisdiction? A City? A County? - What version of NEC are they currently following (and do they have a web site where they list all the exceptions and changes they make to it) - My county follows the state code and the state code follows 2017 NEC but with modifications.
I wonder if we can find a pre-canned spreadsheet / calculator tool for the load calcs that apply to the version of the code you are permitted under.
Technically you need to go pull nameplate values from all the hard wired stuff (AC units, furnaces, jacuzzi, dishwasher, disposal, ovens, etc...) - some spreadsheets/tools I have seen have estimated values
If I were you, I would consider getting one of these:
The Sense Home Energy Monitor I have one and it is fantastic for letting me figure out how much power my house is drawing. While this does not help NEC wise, it could help you gain a lot of comfort in how close to the margins you are or are not power wise on your mains. I would buy a 15a 240v breaker to hook it to and put that in your main panel (it needs like zero power, but it just wants 240v so it can monitor voltage on both phase legs).
I just looked through the 2017 code for AC vs MC and there is a section about AC being limited to 60c insulation ampacity tables if run in insulation, but I don't think it is derated in any other situations. I did not see any notes about any limits on MC cable, so I am assuming that is good at the 75c rating.
Where do you want to put your wall connector? Pictures? I used EMT hard pipe conduit for mine. I think it looks a lot cleaner, but it is kind of complicated. Exactly how far are you going? Would "flex" be an option? They sell like 25' 3/4ths inch spools at Home Depot.
Here is my conduit I bent to my wall connector (outside) - I did a lot more panel work after this picture was taken
