In countries like Germany, balcony-mounted solar panels are all the rage. But from breaker-masking to voltage mismatches, America’s grid isn’t ready for it—yet.
I mean, your outlets definitely are, compared to what we have as a standard.
I will take Technology Connections’ opinion on it over yours, but yes having two pin outlets where if you start plugging it in the live connection is exposed during the process is very much stupid
Our household wiring standards are intrinsically safer than the UK. They need the overbuilt outlets and plugs that Technology Connections likes, because the UK took so many shortcuts on their building wiring.
Can’t really fault them: they developed those standards during a massive copper shortage. To minimize copper use, they ran as few circuits as they could, which means each circuit is drawing absurd loads. They developed “ring circuits” which used undersized wiring and are one loose wire away from an overload. They had to build excessive protections into their plugs so they could safely plug every device they owned into one high-power circuit.
He did day that about our plugs a lot. Maybe you would you like a link to the technology connections video saying basically exactly what @chronicledmonocle@lemmy.world said about our split phase 120/240 setup then?
Except with proper arc and ground fault protection on a circuit, which is mandatory on basically everything in North America now, you could half insert a plug and stick your tongue to it without getting a shock.
Neutral and Ground are bonded at the first point of disconnect, which provides two paths to ground in the event a ground is lost was my point. Not that there are somehow “two Earth’s”.
Most of Norway (my house included) is still stuck on IT, so 230V phase/phase.
The only place it really sucks is for modern induction hobs where 25A @ 230V is a bit low (5,75 kW, max on mine is 7,2 kW) and the EV charge box (3,6 kW or 7,2 kW max instead of 11 or 22 kW).
They are however changing to TN for new areas.
Upside is that the earth current will be very small when you have a fault, so the system can function with it. I believe this is why critical institutions like hospitals run IT and not TN/TT.
American electrical systems are split phase 240V. If you want 240V, you just connect between both halves of the phase.
America has a lot of stupid, but the majority our electrical systems are very much NOT one of them.

We used dozens of properly-sized circuits.
Yeah, but why compare it to UK? It’s the US of Europe, compare it to the European standards.
You referred to Technology Connections. Unless I’m mistaken, he had an unhealthy obsession with UK plugs.

And that’s better than 3 Phase 230V in what way?
Lower voltage is less deadly.
Having a multi grounded approach provides multiple layers of safety for shorts.
Just to name a few.
If Voltage of AC is above 50V, it will break your skin and then the current and time kills you.

Multiple grounds? There’s only one ground. You’re walking on it.
120V/240V, Split-Phase – Center-tapped
120V/208V, 3-Phase – Wye
120V / 208V & 240V, High Leg – Delta

It’s the same with 3 Phases, as seen in the source I provided.
Neutral doesn’t work as an extra safety line, because it’s connected to neutral in the device, not to ground.
Maybe dont make ridiculous claims when you don’t know what youre talking about. I hope you arent an electrician.
The majority of the rest of the world has 220-230v per phase, with three phases. using all three phases gives you access to ~400v
Yes, and where I work the HV line is several times that.
