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.
Oh, America? The one still clinging to 110V (thus more current) and in some cases using aluminum wires? The one where safety standards are for wussies?
Yeah I wonder why.
In the USA, by and large, homes are supplied with 240v with a neutral in the middle. So each phase is 120v. And we can access 240 by simply going across both phases. Literally every house I’ve ever been in my whole life has had 240v to the panel, including ones built before anyone on Lemmy was born.
The only places this isn’t true was a couple of large apartment complex I lived in for few years where it was 360 to the complex 208 to the unit and 115v on each phase.
If you took out the neutral, we’d have 240 exactly like Europe. In theory (definitely not within code), on 90+% of houses in the USA, you could just wire the neutral to the opposite phase as live that the circuit is already on and get the full 240v to every outlet in the house (DO NOT FUCKING DO THIS). Each phase that we have only exists in the context of the neutral, and the neutral is strictly optional(though common) in the context of things like high draw devices.
As far as your aluminum comment… First, why aren’t you saying “aluminium” if you’re not (seemingly) American? But you realize that aluminum works perfectly fine for power delivery right? The EU uses aluminum in places too…
“Europe’s energy transition is about one thing, more renewable power production, and the power produced must be transported over long distances. Aluminium is crucial for transporting electricity to where it is needed. By expanding the capacity to deliver low-carbon aluminium from Norway to the EU, we help ensure that the infrastructure, the very backbone of the future energy system, supports both Europe’s security and climate policy goals," says Kallevik.

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.
America has a lot of stupid, but the majority our electrical systems are very much NOT one of them.
What? America has one of the most unsafe electrical systems in the world. You might as well just stick two unshielded wires out of the wall and be done with it, it would actually be more convenient about the same level of safety.
As for crossing the phases, yes you can do that but how many outlets are actually set up like that, you certainly won’t find an outlook configured like that in a bedroom. Each household probably only has one or two 240 volt outlets.
American electrical systems have bonded neutrals and grounds at the point of disconnect, so in the event of a ground fault, there are multiple layers of safety involved.
Lower voltage by using half of a split phase 240V means shocks are less deadly.
Electrical code also requires Arc and Ground fault protection on all circuits.
The biggest advantages to European electrical systems are smaller and fewer conductors, due to higher voltage, and appliances like kettles can draw more watts as a result.
Both systems have advantages and disadvantages, but saying that American Electrical systems are “the most unsafe electrical systems in the world” is bullshit. Visit India where people regularly hook up unsanctioned taps to live power lines or Central America where they put electric hot water heaters literally in the shower, conductors and all, almost always by Handyman Juan who doesn’t hook up any ground fault protection.

Except that we have 240v?
Why do people overseas keep getting this wrong?

American electrical systems are split phase 240V. If you want 240V, you just connect between both halves of the phase.

We used dozens of properly-sized circuits.
