I understand it’s only about 20hz, which is why it gives you that interesting jiggly feeling instead of a good Wack like mains power at 50/60 Hz does. When I was still a young buck in my early 20’s I worked in a mid-sized company and one of my duties was to maintain our POTS lines; my boss who might have been a sadist would often have me remap the phone lines mid day while the lines were in use and insist that I was not to busy any lines out. I can only amagine my coworkers delight at the inventive array of profanity that would come out of the wire closet when the reception switchboard would light up during these sessions. Sti got my lines man’s handset stashed somewhere…lol

Jamie Spinelli’s job as a case manager for Community Services Northwest takes her to parks, homeless shelters, the jail and…

Sure you can say it’s cultural and you have to take this into account. It’s still bloody dishonest though! Just means their culture is dishonest. Same place where people skim fat out of the damn SEWER to cook food, and it ends up contaminated with all the industrial chemicals that were illegally dumped down the sewer.

around the town of Wentworth in New South Wales the feral pigs are huge, there are lots of them, the scrub is very thick and even back in those days you were not allowed to use a semi automatic centre fire rifle of any kind. The boar in question had lower tusks that were 5″ long.

I often say this, and I will say it again: just because a thing is often done poorly, foolishly or dangerously does not in and of itself preclude it from being done properly.

my first “real” job was in a video game arcade back in the 80’s my boss was a really cheap prick that used to buy asian cocktail machines that were “native” 110V, with a 240V to 110V step down transformer wedged in where it would fit, my second day I was fishing out a 20 cent coin that had missed the coin box, I got “zapped” hard enough to blow my finger nail in half and stop my heart.

The 20% derating is not something that everyone just knows, its part of the NEC. A 12AWG cable is actually capable of handling 30 Amps, but not according to the NEC’s derating requirements for wire temperature rise limits.

First, some background. I am a design engineer working on safety of life critical hardware design and technology development for a military application. I noticed this project a while back, and I invested some thought into how I would design the system.

Chances are almost anything you would want to power on and off through a Smart Plug will work. Lights — whether incandescent, LED, or fluorescent — are compatible as long as they are standard devices intended for use in the home (something like a street lamp or traffic light probably won’t work) and should work flawlessly. Audio-visual equipment should work provided it doesn’t need a power cycle through the built-in switch, and other smart devices like cameras or home hubs should work just fine.

Your friend reminds me of a domestic main voltage electrician that would test with the back of his hand. He’s dead now.

Might be safer your way, since you’re transforming down, then back up again. Using a microwave oven transformer means horribly high voltages in the middle of the thing, and should, by chance, some insulation fail, or a bit of an arc, or whatever…

Of course a safe mains powered heater is possible, but you need a double insulated cable (which is stiffer and heavier) and a reliable strain relief for it. You have to permanently bond the heater PCB to the glass print bed with silicone. You need a fuse and a thermal cut out (thermal fuse) for fire safety, because the available power in the mains circuit is much higher.
