Turn a wall outlet into a wireless charger with the Legrand Radiant | Lrd12 Overload Relay

The first was when I was a wee, messing w/ a big 24v motor w/ weight (read: kickback voltage as it spools down && lots of amperage) and I turned it on w/ my hands on both leads…

And now you know why companies react the way they do. It would be like someone going around deliberately ruining your reputation, and there’s little you could do about it.

We frequently come across warm circuit breakers, warm dimmer switches, and even warm electrical panels during our home inspections. So how warm is too warm? It depends. I know, it’s kind of a blowhard answer, but there’s no one-size-fits-all answer.

You are not understanding something correctly with these statements. You do not want a “hot wire” until you get to where the heat is needed so you have to use thick wires if the voltage is lower between your source and destination if you use a lower voltage.

On Wednesday, Flake voted against advancing controversial nominee Thomas Farr, a North Carolina lawyer who is up for a district court spot, during a Senate floor vote. And since then, Judiciary Chair Chuck Grassley canceled a committee meeting that would have included votes on more than 20 judicial nominees, apparently due to Flake’s key vote in committee.

people remember “the good old days” and they forget all about the horrible accidents and fires and massive death that came from ignoring fire regulations

• Circuit conditions such as the peak voltage and current during the surge event • The MOV continuous operating voltage (should be at 20% above maximum system voltage under normal conditions) • The number of surges the MOV must survive • Acceptable let-through voltage for the protected circuit • Any safety standards with which the circuit must comply

Um, Though I live in Oz where we have 240 volt mains, I can see a big error in how it is explained. On, you get two different “phases” on th 110v side of things to increase the measured voltage.

Five vs Ten amps is a big difference in heating in the power factor correction circuit of his power supply. If you find a data sheet for similar power supplies, they are always 1-3% more efficient on 220Vac and run cooler because of it.

Creating a PCB heat bed isn’t an art – it’s a science. There are equations and variables to calculate, possibly some empirical measurements by measuring the resistance of a trace, but Ohm’s Law is a law for a reason. If you do things right, you can make a PCB heat bed perfectly suited for the task. You can even design in safety features like overcurrent protection and fuses. It can’t be that hard. After all, your house is full of devices that are plugged into the wall.

• Assess your situation: How frequently do you experience power outages? Are they a few hours or overnight? (Most outages usually last only three hours, says Paul Hope, senior home editor for Consumer Reports.) Is your home habitable without power? Could you make it for more than a few hours without heat or air conditioning? How much food do you typically have in the refrigerator and freezer? What’s your level of sanity when there is no power? If it makes you anxious, miserable or just plain nuts to be without electricity, a generator may be better than Xanax.

220 volt +/- 10% isn’t really a good design standard. As it doesn’t live up to the requirements within the EU to start with.
