Does Tesla Make The Best Value EVSE For Non-Tesla Owners? | Lrd12 Overload Relay

So it’s – what happens to this board at 110 Volts and what are the consequences and the same for 240V, 1000V 10000V, ALL of these voltages. So it’s about what voltage will cause consequences and NOT what it is going to do at a specific assumed voltage, or more to the point ** where are the first points of failure with increasing voltage and what are the consequences.

Many people do not own their own home and must deal with a landlord, who may feel that providing a high-quality 110 volt receptacle for the car to recharge is the end of their responsibility.

Speaking of mains power and gas pipes, I live in a 100-year-old house which has some rather dubious wiring (though, perhaps not as bad as the knob-and-tube it started with). The kitchen’s gas range had been in place since puke green was the preferred color, and its power cord (for the clock & timer) was, unbeknownst to me, seriously frayed. The range’s gas inlet was connected to the shutoff valve on the wall with one of those scary-looking flexible tubes (not a modern, yellow insulated one, but rather bare metal). Well, one day the range got pushed back for cleaning, and the exposed hot lead in its power cord brushed that gas line. ZAP!, followed by a roaring jet of flame from the large hole now in the flimsy gas line. I couldn’t get close enough to the shutoff valve to use it, so I had the frantically seek out a big wrench and shut off the gas where it enters the house in the basement. By then the wall behind the range was well and truly aflame (way too big for my wimpy little fire extinguisher to deal with), so I threw pans of water on the fire. I figured the breaker for the outlet the range was plugged into had already tripped, but it later turned out that the contact had been too brief for that and I was throwing water on a live electrical circuit–no harm came of that, fortunately.

(So your distribution wire can be thinner, and so cheaper, mainly because you have less current, but also because you can have a slightly higher voltage drop with less consequence !)

Maybe what should be done is a special 240 outlet be developed and installed in all new construction (1 per garage). Something with safety features like thermal monitoring built into outlet. This would probably cost less than all those annoying ARC fault breakers I am required to have…

China is a shithole. Business-wise it’s like the West was 300 years ago, when your “flour” was cut with chalk dust and all the rest. Except apparently in Chinese culture it’s seen as enterprising and showing initiative, to concoct little wheezes like this for a profit, rather than the thievery our own culture for some reason sees it as.

I’m not remotely an experienced sports shooter, so I can have trouble tracking fast-moving subjects under the best of circumstances. Already finding tracking fast action closely challenging, I found tracking fast action closely based on a series of static images delayed by 1/10 second or more was quite a bit harder still. After a little practice, I got better at doing so, but I sometimes found myself resorting to tricks like keeping both eyes open while shooting, or shooting in short bursts and using the time between bursts to get the subject properly framed with full-time live view again.

There are people that play with high voltage stuff like Tesla coils, induction heaters etc. Now those know enough to respect high voltage.

“The Psychopath Test” by Jon Ronson is a great book about it, the guy who invented the checklist now used to diagnose psychopaths, has his pet theory that psychopaths with power are the cause of many of the world’s ills and inequities. His name’s Bob Hare, and he probably knows more about it than most other experts.

If it is a three phase installation then there are four wires run. These are three phases and the star centre point or neutral.

Temperature swing in the water heater may be about 50K, incandescent bulb filament temperature swing is closer to 3000K. I doubt there is much variation in the resistance of the water heater’s heating element

The AVIC-W8400NEX flagship has a 7-inch capacitive touchscreen, while the AVIC-W6400NEX has a 6.2-inch capacitive touchscreen, and the AVH-W4400NEX has a 7-inch display with resistive touch capabilities. The receivers support both Google Assistant and Siri and can operate wirelessly via Bluetooth, Wi-Fi, or wired through a Lightning connection. Additionally, you can control your smart home devices through the units, including things like a garage door, locks, or lights.
