don't y'all have 220v power over there?

We're on 110v in the US

You might be surprised to know that 220v is pumped into houses in the US but is split at the breaker box into 110v for each breaker.

I assume that the US is like Canada, you have some 240v outlets (with different shapes) for things like clothes dryer, oven, possible welder in the garage, but outside of that everything is 120?

Yep. The plugs are kind of random though. My old dryer, my new (used) dryer, and my stove are all 240v and every one is a different socket. It's weird. I think my RV hookup is the same as the new dryer though, which matches my little generator.

The plugs being different is for a purpose I think. In most houses the oven and the dryer use different wiring size because they pull different amount of power and you don't want to plug an oven in a dryer outlet.

I thought that too. But it turns out, no.....

Still, only kind of. My oven and dryer are different plugs with the same amperage rating. They're actually wired into the same breaker..... I don't really like that but I don't have the space for a new breaker to fix it, and that's how it was when I moved in. So I can't run my dryer and stove full blast at the same time lol.

The different plugs do have different uses, but they're not strict and they can be interchangeable. I found out mine were wired together because my old dryer outlet was different than the new one, but the wiring met the amp requirements so I just took the old socket off and put the right one on. 30A/240v but different plugs for the stove and dryer. It's kind of nonsense.

Ah the fun of old homes, years and years of DIY hack jobs with wildly varying quality lol. In a similar boat with my home, slowly trying to improve things as they come. I just replaced all the outlets in one room and found just 1 was on a totally different breaker - luckily I was checking them individually instead of assuming the breaker took care of everything.

Those are the nominal or 'average' voltages. Nowhere has 100% consistent voltage supply. The UK goes from about 216v to 250v. If you were to plot the AC sine wave, the peaks would be nearer 330v RMS. But that variance is of no damn use to anyone who makes devices, or the consumers shopping for something compatible.

So a nominal is used, a nice easy number for everyone to read and go 'oh yeah, that works in my wall socket'.
