But at the very same time, if the rectifier dissipates enough energy for this to be a concern, then it is probably a poorly designed power supply to start with. As most power supplies will be designed for the voltage range of 110 to 250 volts AC. And as it will draw the most current down at 110 volts, then this is where the manufacturer has their specifications chiseled in stone, as if we want 1100 watts, then we need at least 10 amps when we have 110 volts AC on the input. This means that we “effectively” have 5 amps to dissipate per diode.

At the risk of being labeled a pedant, I’ll remind you that Mike isn’t billed for power, he’s billed for energy, and you didn’t say how *long* you’d expect to draw 3 kW for free.

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.

Online reviews are useful when you’re on the hunt for a trustworthy electrician. If the person with the lowest quote also has the worst ratings, it’s worth shelling out a bit more. If that cheaper electrician messes up, you’ll just need to call me (and my higher price) and pay more overall.

Zaprodk bitches about the absence of a fuse — which is clearly explained to be located on a separate power entry board.

Flake, along with Sens. Chris Coons (D-DE) and Cory Booker (D-NJ), attempted for the second time to schedule a floor vote on the bill protecting Mueller on Wednesday, but it was blocked by Sen. Mike Lee, who argued that the legislation was unconstitutional (a longstanding conservative argument, explained by Vox’s Tara Golshan here). The bill would ensure that Mueller could only be fired by a Senate-confirmed DOJ official and enable the special counsel to review any firing.

The reason may be the cost of getting UL approval. You can buy off-the-shelf, UL approved, 12/24VDC power supplies. Once you are working with 12/24VDC most products don’t need further UL approvals. But — if everything is mains power you are going to have to pay for a new round of UL testing. That can be $10,000 or more.

Having a ground helps in the case of appliances with metal cases. If the hot wire comes loose and touches in inside of the metal case, it is shorted to ground which will trip a breaker. Otherwise the metal case would become hot which is obviously dangerous. Soil resistivity has nothing to do with it and in fact it would be safer if it wasn’t tied to physical ground, that is just done to save money.

It works, but the losses are significantly higher, and if you’re drawing much power you’re going to need heavy, expensive low-voltage sides on both transformers. In a pinch, fine, but if you’re going to be buying them it’s better to spring for a single transformer.

I can’t speak for 75 mph, but the EPA for the regular hybrid Niro is high 40s to 50 mpg highway. Since this car uses the same Atkinson cycle 1.6L engine, I’d expect about the same fuel economy.

Mains powered heated glass plates are common place in catering, same deal as a car back window, the heating wires are on the other side from the “working surface” these things can tolerate touching and even fluid spills, why reinvent the wheel, the solution is already commercially avaliable.
