      Oh my god this thread is driving me nuts noone understand how AC works. Neutral is not bonded to earth ground that defeats the whole purpose of the GFCI. Dear everyone please stop assuming you get things if you don't get them.https://twitter.com/SwiftOnSecurity/status/1012519464137523201 …

      Ok ok ok ok look, ground is fake. it isn't a thing. There is no such thing as ground. We make ground up. Its a reference to set the baseline voltage of anything else in the system.

      AC power is transmitted as a sinusoid centered around said reference. Switch hot and neutral and you have a negative sinusoid. A negative sinusoid centered around 0 is a positive sinusoid with a phase shift of 180 degrees.

      And no earth ground and neutral should not be connected anywhere that is such a bad idea it breaks the GFCI (ground fault current.... i don't remember). It's not safe. Ground is a reference, earth ground is a "safe emergency path" effectively.

      Well they should be connected *somewhere*... Usually at the distribution transformer. And nowhere else.

      Fun fact: one of the reasons why earthed 3-pin sockets are uncommon in Japan is that the design was patented. The patent was owned by the late former boss of the company I work for in Tokyo (whom I met once on my first trip to Japan). He was an interesting dude.

      Why would that make them less common though? This raises more questions than it explains

      Had to pay royalties on it. So instead of the patented design people used the separate earth screw terminal hack.

      Bad™ This is one of those instances where the government should have excercised their ability to ignore patent violations in the name of public safety.

      Well, ground had always been a big meh thing here for stuff that isn't big appliances. The only things that are grounded in my apartment are the microwave and washing machine. No other grounded outlets. Stuff is supposed to be double insulated.https://twitter.com/marcan42/status/922703784719015936?s=19 …

          I mean, yeah, but I appreciate the availability in systems to know you have a safe tether to use to protect against ground loops if desired. Good for design stuff imo, but it's definitely not necessary if you design for it right. Just kinda like to have it.

          Oh I agree. Just saying in *practice* things seem to be pretty fine, so it's not a huge public health hazard. But it would be nice to have grounds (and new construction usually does, I assume the patent expired). I'm tempted to add one to my apartment socket myself.

          It has always amazed me how much cheap-ass shit in the US is _not_ double-insulated. Or even single-insulated! Ordinary table and floor lamps were a shock hazard before polarized plugs were introduced.
