As far as litigation goes? I know enough about Chinese law to know that it’s really up to Fotek and whether Fotek applied for trademarks in China or not, and whether they did the rest of the intellectual property legwork in China (which is really tricky because China doesn’t use common law like Western countries do, so it’s a harder system to navigate). If they did, then yea, the counterfeiters could probably be sued although it’s a whack-a-mole game, the counterfeiters come up faster than they can be whacked down. But if Fotek didn’t go through the China IP process to protect their brand, then the counterfeiters may have actually applied for the trademark themselves in China, gotten the right to use the name, took the likeness and everything, legally (at least in China). Best Fotek could do at that point is try to keep them from being imported into the USA (similar to the Sparkfun fluke-colored DMM’s a few years back) but again that’s a whack-a-mole game that they wouldn’t win.

If the device does not have it owns fuse/breaker and relies on the upstream one, it had better be able to handle the full rated current without catching fire.

Of course, after buying a 1000W PSU, I kept getting intermittent shutdowns and freezes after 30-60 minutes of gameplay or CAD work, despite remaining perfectly stable while mining for days at a time. The GTX670 has no backplate and last year a fan screw vibrated loose and fell on top of it while everything was running. The motherboard was toast so I ungraded it and the CPU (AMD FX9590), but the GTX670 itself seemed okay. Apparently not.

Agree on stupidity, but psychopaths have gotten an undeservedly-bad rap. See this: http://www3.nhk.or.jp/nhkworld/en/tv/firstclass/201604140600/ I’m proud to say that I scored 19 (average-level psychopath) on the the quiz that was presented.

VAC says: “The two 120V legs are *in phase* with each other.” Of course they are not. *by definition* if they were in phase there would be no voltage difference between them. The two 120V legs are 180 degrees different from each other, so the difference between them is 240V. Which is (of course) the supply voltage.

A vaccum forming table design I looked at used ceramic rods made the same way with reflectors to evenly distribute the heat. I also own an electric kiln designed to heat and temper glass so a page can be taken from that design.

I’m certainly pleased the US Air Force along with the wind turbine industry taught me just a few skill sets in getting that Level 2 service expeditiously installed.

I don’t know where your grid is, but in North America, high voltage lines are not 100 kV. 19 kV and 69 kV are typical for local distribution. 115 or 138 kV for intra-city, and 230 or 500 kV for most long-haul lines, not counting the whacky HVDC or EHV stuff.

The main issue would be shock protection. A bare PCB with solder mask probably won’t cut it for UL or CE. If you have vias in the element traces, it will probably be really dodgy. On a commercial product which you can’t (are not supposed to) open and tinker with, there is probably a way to do this easily. For a DIY printer, not so much.

If a consequence is human death then obviously that is completely unacceptable. If it blows a fuse at 1000V then good! If traces vaporise disconnecting the mains at 10,000Votls then well done! Where is the weakest point (lowest creepage clearance for the exposed voltages) and what are the consequences of a flash over at that point.

You may be confusing voltage drop ALONG a power line with the voltage BETWEEN lines. Maximizing the latter will transmit same power with less current, minimizing the first and hence Ohm’s Law power loss through transmission.
