- Did you know that both red and black wires in AC circuits are ‘hot’, but in DC circuits, they are positive and negative? Confusing, I know, but clearing up the confusion of wire colors is exactly what I’m going to teach you here in lesson #3 of this Wire Basics chapter. Don't let wire colors baffle you-watch this episode to get the clarity you need! Or, save time and hassle by purchasing our pre-made wiring kits at shop.explorist.life 😉

On aircraft, all the wires are white...lol. luckily, the wire is marked. I just rewired much of my boats AC and DC and i wish I would have used yellow for the ground. Its what all the cool kids are doing now. Also, if you sell the boat and it gets a survey, yellow ground wire indicates recent upgrades
My favorite is finding only black wire in a DC power circuit, for both positive and negative leads, and distinguishing the positive by only using a section of red heat shrink insulation at the wire lug. I usually see this in battery bank wiring where the installer used what was available.
Red and black, got it!!😆 Australia uses white as earth return in 5, 7 and 12 pin trailer plugs.
Winnebago uses yellow for DC hot and white for DC negative.
Came here to make the same comment.
For further confusion, white is generally ground in commercial RVs. 🙂

Any concerns/warnings for folks buying wire online, to be aware of copper coated aluminum wire being sold as copper?
I'd just buy it from us at shop.explorist.life and take the guesswork out of it. 🤷♂️😉 We are the same price as Amazon but we actually have physical hands on our wire and kits every day as we make our kits in house so we have some quality control over everything.
Personally I run yellow negative for everything 10 gauge down and black negative for everything 8 gauge up. Mostly because it's a pain trying to get 8 gauge up in yellow, but also, who is running 120 volts in 8 gauge or up
Hi Nate, Good video! Like a lot of people, I'm navigating DC outlets and using a mix of cigarette lighter sockets, SAE, and Anderson Powerpole for 12 VDC outlets. SAE is my pick for the composing toilet vent fan. Being a ham radio operator, I'm following the traditions of ham radio for the 12 VDC Powerpole connectors for radios. But, what about 48 VDC, which seems to be on the horizon for DC appliances? Can you do a video on higher voltages of DC and standards keep them straight, plus any connector standards, which will prevent plugging a 12VDC device into a 48VDC outlet.
After spending months figuring out how to build my system and buying and installing it all...my ceiling fan was wired backwards...who'd of thunk??? White/Black/Red??? It doesn't really matter does it?? Manufacturers think we're all experts...Well, now I know.
In summary - To know for sure what *your* wire color is, trace to source/load and grab your voltmeter!
Should be easy.
Well Ffff...
