This hack is ridiculous and a hazard. The NEC bans the use of MWBC’s that don’t use a common circuit breaker tie-bar. The tie-bar causes both halves of the 240VAC circuit to turn off incase of an overcurrent condition.

I’m wondering why nobody is simply rectifying a 120vac input for dc wiring the secondary coil? It means you don’t have to swap the coil location or use a dc power supply. I have a trans with a secondary resistance of 82ohms. Putting 120vdc through it would be about 175watts (assuming I do a good job of determining wire size and 1.46amps is ok)

Maybe they’re at the same kind of place Rubicon were during the capacitor plague, actually made by Rubicon caps were okay, exact visual copy fakes and Rulicons, Rubicows Rubycoms etc etc were not

And for example the max continuous current one is “rated” for is 20A, and when I calculated the values without any heat sink, I should be able to run about 700mA. A lot of people forget to do this step before de-rating.

Growing up in a family surrounded by electricians, we were always discussing codes and theory around the house. Much of what I know came second-hand through my dad but also through Mike Holt, a well-known electrical author and instructor I now have the privilege of calling a friend.

Let’s see, you’ve pooh-poohed my 12kV hit and [Scott_Tx]’s 90V one, so I guess 440V three-phase (was it the high leg, or one of the low legs?) is the sweet spot for you. Lucky for our edification that the boots did indeed save you. I knew someone who was quite thoroughly taken out by 220V in a basement while wearing (presumably damp) leather sandals.

“I don’t think” – hehehe I’ll agree with that. My utility company provides 3rd world electricity in August. Most days the juice drops to 103 without anything on in the house. I’d love to have as much as 110. Fortunately, the L1 car charger works down to 100, and the L2 stuff works at 187 – the lowest I’ve measured. 5 big reasons why the juice is so bad, but then I’m not paying for the loss, so its not a biggie with me. Just worry a bit about the refrig and freezer.

Air conditioners work hard to keep you cool, and you don’t realize how much you rely on them until you are stuck in a sweltering room with no relief. If your air conditioner suddenly goes out, there is no need to panic. Follow these simple steps to bring your A/C unit back online and you may avoid the need to call in an expensive professional.

You can, but it will likely not be very useful. The losses in the two transformers will be such that you won’t be able to draw much current from it and most appliances won’t work.

Yes, I have seen that sometimes (floating oscilloscope) but I always thought the good way would be to power the DUT through the isolation transformer and leave the oscilloscope safely earthed. Of course you sometimes need a bigger iso. transformer this way.
