Edit: great approach to understand the matter: https://youtu.be/BGD-oSwJv3E?is=Fe1FimqTCvN-aY1u
I was looking at some transformers:
But also
If it outputs 12VA (12V * 1A) of apparent power, then it receives/works with (?) 12VA apparent power. That means that the current in my 230V wall outlet is 12 / 230 ≈ 0.05A. Even a button cell can supply 0.15A per hour… This leads my uninitiated head to believe, that it is mainly high voltages that are not compatible with life.
Please advise? 🙃
Huh, TIL.
That doesn’t seem to be supported by my research. Standard breakers are designed to trip based on a function of over-current and time, but that doesn’t preclude any breakers from using current alone.
It won’t. I checked. A more detailed spec sheet will, but not a basic one.
They sure look like they are. The rating is the current that the breaker can sustain indefinitely at the reference temperature. And it sure looks like the EU rates them the same way.
Of course they can. You aren’t a ground fault. A load of 100mA on a GFCI is perfectly normal, and the same load will kill a human very quickly.
If you cannot understand the BASIC fact that a circuit breaker can ABSOLUTELY conduct more energy than its rating before it pops… then you are simply too stupid to understand what I said. Period. Absolutely. Good job being so dim.
They look like they are … to an ignorant incapable of reading comprehension. Which is one reason why the standards are made fun of.
Care to explain your reasoning, then? Or did you just want to feel smug?
Edit: boy howdy, looks like you’re completely wrong anyway. While the breakers certainly don’t trip at their exact ratings (good thing I never said that they did) and do take time to trip for certain loads above their ratings, there is an absolute cutoff, somewhere between 2x and 20x their rating depending on the breaker type. So my number was a bit off, should have been 30-500A depending on the breaker type and rating, but it was a lot closer than “never ever at all.”
