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.
The only place neutral is bonded to Earth ground is at your electrical panel, open it up and look at it. The white wires will all be screwed into a giant bus bar, which makes electrical contact with the electrical panel enclosure. All of the earth ground leads are also screwed into a bus-bar linking them all to Neutral.
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.
Capacitive or Resistive Voltage Dividers are not really an option for this device since the ESP8266 draws a relatively high current. You would have a high power dissipation (resistive) or a VERY large capacitor. A more complex design or a small transformer has to be used here.
While the Sony A55 and A33′s singular claim to fame is its exceptional shooting speed, that’s only part of what it has to offer. Just in the last year, Sony has used its high-speed sensor technology to create a number of innovative new camera features that, on their face, have nothing to do with high-speed shooting. This hands-on report is already running far too long, so I’ll just make brief mention of some of these special Sony modes here. Even if you feel no need for 7 to 10 fps capture in your personal shooting, these special exposure modes alone would be reason enough to buy one of these cameras.
Popular brands of EVSEs include ClipperCreek (one of the first companies to get into the home changing business), Siemens, JuiceBox, AeroVironment, and ChargePoint, among others. An online search can help you find a unit that comes with the features and power output that meets both your needs and budget. To make matters easier, you can purchase either of three popular ClipperCreek charging units directly from MyEV.com. Coming in both portable and hard-wired configurations, they’re priced between $379 and $565. Each of our EV for sale listings features them under a “shop for chargers” tab, or can check them out via this link.
A REAL Fotek is a good brand ….. however some dishonest shops in China are turning out fakes by the thousands ,,,,, I got burnt by a fake Fotek 25A DC SSR for a printer a couple of years ago and the 2nd or 3rd time I used it the MOSFET went up in smoke although nowhere near this spectacularly …. I ended up replacing it wtih a 100A Fotek that I could ascertain was genuine and it’s been working ever since
Such an awful practice and terrible idea. I have an EV and would never do this (me being an EE). I decided to make this correctly and I installed dedicated #10 cable from the auxiliary power distribution box to the EV charger as a permanent connection, no plugs no unsafe contraptions, and following all the NEC codes. Those cables you used and the crimp terminals aren’t suited for the current rate. Check them if you don’t believe me. Crimp pressure plug in terminals are rated for around 6 amps of continuous AC current and I hope you used at least 600 A.C. volts insulation cable… Bad, bad idea.
It takes volts to push amps, and if your body tripped a 1A breaker you’d be dead. For shock hazard, 110V is safer than 220V regardless of the size of the circuit breaker. But for a given power draw the possibility of overheating your wiring is lower with 220V, which is why I use it in my (American) shop whenever my equipment supports it.
If I scan a ceiling and I find a cold spot that doesn’t make any sense, I dig into it. Maybe it’s a plumbing leak from above, or maybe it’s just a cold water line that’s touching the ceiling. That’s where a moisture meter comes in handy. Ok, I’m getting sidetracked. Let’s discuss some electrical examples.
The real problem with mains voltages is that somewhere, some day, some bonehead will manage to fry himself – and the media will blame the maker movement for it. I’ve already seen far too many absolute beginners planning to wire up their home appliances to an Arduino as their first project…
I don’t disagree with you, but I think someone renting and is considering an electric car will understand and accept charging limits before their purchase. In my opinion those are early adopters. My son wants a model 3. He test drove one and could probably afford it, but he’s waiting until he can charge it. I see plenty of apartments around me are installing EVSEs now. I would imagine market forces will get more landlords to install them in the future.
