The general rule of thumb is that below 30 VDC, an AC rated switch will work fine.Switching DC is different and more difficult than AC. The switches will probably work but may degrade unless DC rated. Plenty of 12v DC switches available.

It's quite fun to be in this stage of planning, I get it! Sounds like you've got a good approach and understanding of what you're in the middle of.I appreciate your thoughts on this tread. I really do
And I have had my suspicions that 12v appliances are not great. thank you for the input
My view is more "in case". For example I may want to use some lamps, that have sentimental value, in the 12v. I have also considered converting an old Singer sewing machine to 12v.
It will be a small place that I build. Probably no more that 5 rooms. So I figure might as well put in a 12v outlets, alongside the 120v outlets, because it will be my castle.
As a side note- I will defiantly be putting in emergency lighting that is 12v in all rooms. I salvaged a bunch of 12v fixtures from an RV wrecking yard years ago for this purpose. In my mind, 80% of the benefits of electricity is lighting. I even have some heavy duty 20amp commercial grade switches I will use for the emergency lighting switches (think they are any good?
I intend to use the above in a similar matter. However, I plan to use red/black for 12V, green/black for 24V and blue/black for 48V as I will have all three voltages available. A feature of PP connectors (at least for the SB 50 xxx series) is that different colors cannot be mated to each other.https://powerwerx.com/anderson-power-powerpole-sb-connectors#?specs=315
Way better than a cigar connector that somehow meets code in an RV. Nothing sacred about J-Boxes.
All the pictured connectors in the OP would seem to imply other than 12vdc is available.

What are you using at those voltages?I intend to use the above in a similar matter.

solar fridge/freezers at 24v, 48v poe injector for starlink dish and other networking equipment, 48v to run monitor equipment, 12v for some battery chargers, etc.What are you using at those voltages?
do you also use different polarizations?I intend to use the above in a similar matter.

Let me also recommend Anderson Powerpoles and as shown in post #7 you can have a proper wall outlet.
I have used everything from wirenuts, WAGO’s, XT-30, XT-60, molex etc. in more than 50 years of ham radio DC power management.
Powerpoles have (finally) turned out to be the de facto standard which was a long time coming.
Government EMCOMM facilities are even getting on board which took a long time.
Your cabin, your choice but above are a few reasons for mine.
Frankly, it's the same way in construction. Jurisdictions may adopt different versions of the NEC, not necessarily latest. And they may not inspect electrical at all. It's like that here, our county follows X year NEC, but no inspection is required. Enforcement is triggered by "inspection" - which is usually triggered by permit.The RV association adopting the NEC wiring standards isn't the same as legal enforcement.

For me I would only use 120v AC plugs. (In my case 240V AC in Australia.)While I was here, I thought i would ask the brain trust...
I am looking to wire a cabin/house for 12v appliances/outlets & 120v appliances/outlets
Many moons ago... in the early days of the internet... when I was still in my 20s. Someone suggested to use a different plug for the 12v appliances/outlets so there is much less risk of a mishap. Like plugin in a 12v appliance into a 120v outlet (or vice versa)
I have thought of using different color outlets, but that could still cause a problem when I am old, or people visit
I am not a fan of the cigarette plug style
Anyone have any thoughts on what would be a good type to go with? or ones to avoid?

How false this statemment is !The NEC doesn't apply to RVs. .....................
I don't know what's so confusing here. The NEC is not ENFORCEABLE by a government inspection authority in RVs. Your local building inspector won't be visiting your RV and looking for NEC violations. Now, the RV industry can certainly CHOOSE to use the NEC standard. They can certainly slap a nice sticker on it that signals to everyone else how great this RV is.How false this statemment is !
NFPA NEC
Article 551 RV's and RV Parks apply.
This article Information Note
Low voltage systems, refers to NFPA 1192 standards for RV and ANSI/RVIA LV, standards for low voltage sytems in conversions ane RV's applies also.
You should grow a mustache and stroke is maniacally when you're done.Awesome
I finally have a project for all of the paper clips and speaker wire laying around.
I knew that they would come in handy one day.
The OP intent is for emergency lighting and grid-down where 120V is not available.You can just use a "wall wart" that outputs 12V and skip having DC outlets everywhere.
That would save you huge amount of hassle.
Just wanted to make sure the entire use case is analyzed and there wouldn't be more value in having an inverter in that case since it seems there would already be a battery system that is charged somehow to supply the 12V to begin with.The OP intent is for emergency lighting and grid-down where 120V is not available.
Keep in mind that if you value your investment in your RV, you might want to insure it.I don't know what's so confusing here. The NEC is not ENFORCEABLE by a government inspection authority in RVs. Your local building inspector won't be visiting your RV and looking for NEC violations. Now, the RV industry can certainly CHOOSE to use the NEC standard. They can certainly slap a nice sticker on it that signals to everyone else how great this RV is.
Or, let me say it this way. You can build your own homemade RV, and make it roadworthy to all highway and automotive standards, and then you could wire it with paperclips and speaker wire and violate every principle in the NEC, and there is nothing anyone could do to stop you.
