Turn a wall outlet into a wireless charger with the Legrand Radiant | 25 Amp Circuit Breaker

Very interesting article. Being in the “treat it like radioactive anthrax” crowd, I rarely mess with mains level voltage, but I got a peek at what is required to do so. I read the paragraph about the “residual current circuit breaker” and thought it sounded very much like a GFCI (Ground Fault Circuit Interrupter). I clicked the link and sure enough, that was exactly what it was. I was surprised the article didn’t immediately describe it as such, but as mentioned in the Wiki that the link led to, only the US and Canada call it that.

I’m constantly amazed by the use of a giant blob of solder to increase the cross section of PCB traces meant to increase their current carrying capability.

In cases of energy shortfall, we could apply 3% or 6% voltage reduction from our central control, to shed load. (along with asking manufacturers to reduce load, part of their contract) Before real load shedding, switching off supplies. I know. I was a control engineer. Admittedly a few years ago

Sometimes you’ll get a zap across your hand, maybe even a horrible burn. But I like those odds compared to you touched live and it routed current through your heart!

(No portable generator can power an entire house; for that you’ll need a different category of generator, called a home standby or whole-house generator, which will cost $2,500 to $4,500, plus installation, something that can run in the thousands, depending on where you live.)

Interesting idea. You don’t need a 3D printer for this though. Conductive strips or simple wire should work fine.

My grandmother had a set of glass topped buffet serving tables where the glass top had a foil element sandwiched between the glass layers. They plugged right into the wall. No components other than the heating element, line cord, and a neon bulb to remind you it was plugged in. The element terminated with a couple of fused in copper rods threaded to take nuts. Got too hot to comfortably touch, but warm enough to keep your food hot. It should be within the capabilities of a glass/ceramics hobbiest with a kiln to sandwich a foil element between two pieces of glass and fuse the sandwich together.

Knowing the sequence of operation for this type of starting relay can help you diagnose, confirm, or rule out certain service problems.

Does matter since he runs it on DC, even so the lamination are already welded at the factory, its how the transformer is assembled.

Still, the orderly May backdrop registers as bullish, versus the prior three months, punctuated by the S&P 500’s flag pattern pinned to the steep early-month rally.

Once upon a long ago I was tuning a Tesla coil I’ve built with a friend. The coil was driven by a dirty cheap spark gap made with a screw that had to be rotated to change the distance between electrodes. I had to switch off the 6kV primary transformer, ground the terminals and rotate the spark gap, repeating this procedure until the biggest possible spark jumped out of the coil. After repeating it many times, I accidentally forgot one step. I’ll never forget that moment. My arm was thrown in the direction of the wall as if it had its own will and wanted to get through. Not good. Very painful.
