Curious What $750 Gets You? Pics of the Guts of Nissan LEAF’s Charge Station | 19mm Momentary Push Button

Step 4:  Use the V-I curve (Fig. 3) in the MOV’s datasheet to verify that leak voltage will be less than the 300-V ceiling.

To me, this is like the equivalent of cheating on your math homework by looking for the answers at the back of your textbook. Or worse, like getting a hand-me-down copy of Where’s Waldo and when you open the book, you find that your older cousin has already circled the Waldos in red marker. It’s about the journey, not the destination — the process of methodically scanning pages with your eyes is entirely lost! But of course, no one is actually going to use this robot to take the fun out of Where’s Waldo, it’s just a demonstration of what AutoML can do. Reed listed a few more possible applications: “Maybe a fun use would be seeing what cartoon character the AI thinks you look closest to? Maybe could detect comic book forgeries?”

I would prefer, use a circuit (SCR?) to lower the voltage to around a safer value, where we won’t have any problem in the worse case.

Oh well… That industrial relay has ‘almost’ the same contact ratings of a simple songle srd-05v sl-c relay (specifically the C form/single phase). But I’m sure it won’t last as long as 20y+ in such harsh environment.

The device uses two hot and one ground to supply the 240V output which is, in some business where there is three phase power this will be closer to 208V but should still work. Obviously you shouldn’t be doing this unless you know exactly how it works, and we applaud [Nick] for airing these hazards while at the same time supplying the knowledge behind the concerns.

Remembers me of an incident when my mother asked me to fix the extension cord for the electric lawn mower – “please check the cable, the garden worker complained the mower does not work”. I opened the socket type end of the cable, saw a dislodged contact spring and wanted to reseat it. Then I had to feel the other end was still connected to 230VAC mains. It just did not think of thisbefore… But luckily it just stung a little. I pulled the plug and continued my work.

#PreferLinux mentioned switching off at the mains socket. Do that, but still test; that saved me once when the switch was faulty. Yes, that socket was replaced, pronto!

I was mainly thinking about the diff between high vs. low RMS AC voltage but the discussion of AC vs DC has been interesting as well.

Most systems now do not distribute ground (earth) from the MV / LV substation. At the sub the neutral is connected to ground through a low value resistor (<1 ohm) to a nest of earth spikes. Live and neutral are then distributed. At the house Neutral will be connected to a suitable ground point and at that point the earth connection is split off from the neutral. This means that any difference in ground potential is slowly leaked through the big resistor at the substation and it is a big resistor, looks like an oil tank maybe 2 metres high and 1.5 metres across. It is also normal that if there is any equipment at a pole it will also have an earth nest for the neutral wire.

It’s neither a sports car nor a hot hatch — it’s just a tall hatchback masquerading as a crossover. It handles a bit better than most commuter appliances, due to the 258 pound battery mounted low in the chassis. Imagine strapping me, Keanu-under-the-bus-in-Speed style, to the undercarriage of a car. That would let the car hug the road a bit more (and seriously wound your favorite bearded auto writer, so let’s keep this hypothetical).
