In Japan, People Get Charged Up About Amping Down | 19mm Momentary Push Button

Also power the unit directly from the mains ( http://ww1.microchip.com/downloads/en/appnotes/00954a.pdf ) with the ability to power the unit directly with DC when (re)programming the ESP8266

I suppose the other point of note is that compared to 220/230/240 Euro voltages, residential 240 is not 240 to ground. The only things that have such high voltages to ground are either corner-grounded 240 deltas (which are exceedingly rare) and 480/277Y systems (which admittedly I do a lot of work with). I also really like how in the US we have such an extensive system of completely non-interchangeable, unique connectors for all the different voltage and phase combinations that one might find (thanks, Harvey Hubbell!)

Often, the downside to those positives would be an overly-hard ride, but the MacPherson front and double wishbone rear suspension has been tuned to largely cope with what comes its way. There is a firmness that can translate to bumps and surface breaks unsettling the car, but on these Spanish roads at least, even on larger-than-standard 18-inch wheels, they were decently controlled. While it’s no guarantee of success, the development team tested extensively in the UK. There is also an option to fit a five-way adaptive system that includes damping alterations, opening up everything from eco and comfort modes to increasingly sporty ones to be considered – although you’d need to be dedicated to use them all.

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.

You can also see the top of the mechanism for the tilt / swivel LCD panel, peeking out on either side of the electronic viewfinder. The viewfinder itself projects quite a bit from the rear of the camera, a decision that was apparently necessitated by the tight packaging of components in front, including the AF module, popup flash, hot shoe, and microphones.

TJ may also want to mention on his project page that without a choke, the TRIAC will dump out a ton of EMI (that’s why most commercial dimmers have to have a choke in series with the load to be able to get FCC certification).

Sometimes you’ll get a zap across your hand, maybe even a horrible burn. But I like those odds compared to you touched live and it routed current through your heart!

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.

The contacts therefore return to their normally closed position by spring power as the motor coasts to a stop.

If you’re buying an EV, make sure the power outlet or wall-mounted charging station will be located within close proximity to your vehicle’s connecting port. Charger cables usually run from around 15 to 25 feet in length, but that may not be sufficient or desirable if the car’s port is located on the opposite end of the garage from the available power source. You may have to have an electrician extend the service closer to your car’s charging port if that’s the case.

I disagree, I think L1 EVSE represent a real safety concern. People use corroded outdoor outlets, poorly wired outlets, extension cords (without proper checking for damage or heat build up), etc.

It’s not voltage that kills you, it is current acoss the chest ie heart. Hence so called medical coils of the 19th century and high frequency tesla coils and drawing arcs to your skin that do not kill you. I knew a TV engineer that tested high voltage triplers for CRT TV’s by drawing an arc to his finger. The path is the issue and the current available.
