Homes in the US are fed what's called split-phase 220VAC, operating at a superior 60Hz. The phase is split at the step-down transformer, meaning you have an extra piece of wire that runs to the residence.
There's no waste or expense save that extra wire and tap on the transformer, everything else is just cable. You could just as easily feed 220VAC on the outlets in a USA home, if you had said desire - the copper ROMEX doesn't care. Most switching supplies don't give a shit either, they'll run on pretty much anything from 90-250VAC, 50-400Hz.
110 allowed us to do things that Europe could only dream of in the early days, including making radio cheap for the masses by directly heating the series string in a receiver and removing the expense of a power transformer. At this point, there's absolutely no reason to change, all the power hungry appliances are 220 anyway.
You are possibly an electrician. A bird of science and history for sure
I'm not an electrician, but I am an electronics technician. The two professions dance with one another.
Thank You, So sick of transplanted euros trying to pretend the electrical system in the US is backwards because it isn't the way they do it back home. You might save a couple bucks on copper, but you waste it on insulation. Jesus Christ! these guys have master degrees in engineering but that white wire is baffling.
Why do Eurocucks do this shit?
Anything that is 'American' they always shit on. Even down to the temperature and measurement the US uses. What a bunch of faggots that have to have USA live rent free in their minds. I never give a shit for the 'metric' and Euro ways, because I know it works best for them. So why give a fuck about us?
I never hear Japanese do this, if anything they embrace and admire it.
It used to be generating companies in the states were obligated to provide power at a voltage and frequency equal to that of the legacy systems they installed, if said legacy systems were powering some industry that relied on those variables.
About 20ish years ago, I read of a cooper in New England that had equipment that ran on 25Hz, because that's what was available when they started. Since all of their equipment was wound for 25Hz, the local electric company was obligated to provide that.
No idea if they're still around.
