Power Management, Chapter 8: Power Management ICs | 25 Amp Circuit Breaker

Here is something to think about; Those floor finishers were doing this back in the days when “the code” only specified two wire outlets. . These days that would make a few people nervous. No case ground for the sander….

As with basically every other high-end Android phone this year, the Mi Mix 3 has a Snapdragon 845 processor, but breaks new memory grounds by including up to 10GB of RAM. Xiaomi is also bundling the phone with a 10W wireless charger. A 5G version is set for release in Europe early next year.

I wrote a whole blog post dedicated to this topic, titled Hot Dimmer Switches. Check out that post for more info on this topic. If I were to write up a problem with an overloaded dimmer switch, my report comment would say something like this:

I’m confused… “Wire up the outlets for your mining rigs for 240 instead of 120”, shouldn’t you rig it up to use whatever enters your home. Apparently there is a choice, how is that possible, do they run their own generators over there?

I can’t speak for the ‘3’, but you can – since you can at least compare your cost of charging with the 240 – 250 volt cost in the Tesla Calculator.

But 110/120v A/C? that stuff is baby-play, as long as you realize that you shouldn’t use both hands, or use grounding straps, it just kinda buzzes, I’ve played around with TENS devices that had more (felt) kick than it…

AC Amperage ratings of up to: – 37A AC at 40°C – 42A AC at 25°C Compact 17.8mm width housing Output voltage rating up to 660VAC Control Voltage of 4-32VDC High I2t rating of up to 18,000 A2s cULus listed, EAC, CE, China RoHS

The layout looks good too, but I’d recommend for version 2 that you increase the creepage distance between the HV and LV – particularly with regards to the LED. My own habit is to place an actual “border line” on the silkscreen. Nothing is allowed to span that line except for galvanically isolated components (isolated power supplies, opto-isolators, etc).

If you do not know the exact value of each cost, you could enter an estimated percentage based on the cost of goods.

Rob, where would anyone ever get 10,000V from? Or even 1,000? Short of lightning strikes, these voltages don’t exist in the home, or in many factories. Why do those voltages matter?

It’s one of those things that “everybody knows,” sort of. For continuous duty applications (and EVSEs certainly qualify), you derate the circuit breaker by 20% unless you are using circuit breakers and wiring that are specifically rated for continuous duty.

The issue with the DC heated beds seems slow temperature rise. Some bigger builds and beds need a quicker heatbed heater. (In my opinion not needed for PLA) Only for ABS.
