BMW’s iX3 is the company’s first normal-looking all-electric car | 25 Amp Circuit Breaker

Evil Triacs, should be banned by Law anywhere in the World. How is looking a dimmer with Relays? I will love to see a picture. Or an evening filmed youtube video with it, the contact sparks are a free added effect, nice one

If the CH-R and Prius hinted at the dynamic leap that Toyota has taken with these new underpinnings, then the Corolla, with all the inherent advantages that come with being lighter, lower and more compact, confirms them, even in this late prototype form.

Well your musle will clench with AC as well. That’s why friend mine is still among the living. He was an oilfield pumper after n over night thunderstorm there was much equip down because of blown fuses and tripped motor over load protection devices my fried got an a hurry and got careless He reached int a motor control box and grab a fuse in each hand to pull them out. Because of other damage in the box they where energized. The jolt threw him on his ass because his hands clenched surround the fuses the act of throwing him back disconnect him from the electric power as the fuses pulled out out of their holders. I tech school one of the other student got bit by HV inside a TV and it threw his hand way. He wasn’t hurt by the electrical shock, but we kept an an eye him for a while because he looked like he could enter a state of physical shock.

An assessment of a circuit boards durability and or safety should be based on circumstances and consequences and not false assumptions like “this board will only ever have 240Volts supplied to it”.

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:

But despite them being ‘commercial’, they’re still pretty hideous bits of cheap Chinese kit that I wouldn’t trust as far as I could throw them.

the scariest thing I have ever seen/been around was in a fuel terminal at an oil refinery. I couldn’t figure out why we had printers, plotters, Apple II’s and monitors dropping like flies.

253V above. The 3% voltage reduction equalled 5% of the load and 6% voltage reduction 10% of the load I seem to remember. Over 15 years ago.

The Sony A33 includes an internal stereo microphone, actually comprising two separate monaural microphones located on either side of the electronic viewfinder / flash housing. It can also accept external stereo microphones, courtesy of a 3.5mm jack on the left side of the camera body. Alternatively, sound recording in videos can be disabled, if preferred. The built-in speaker in the Sony A33 is monaural, and there’s no manual control over audio recording levels.

Only thing I can think is that it will send more current to high resistance loads like a human body, where lower voltage will send less. That’s the only thing inherently more dangerous about higher voltage, no?

I had a job testing these once, and I can confirm that standard failure mode for overcurrent is some kind of explosion. Usually it was a puff of flame and dust down the leg, but occasionally we’d get a TO220 blown in half
