In Japan, People Get Charged Up About Amping Down | Circuit Breaker Parts

The US had the luxury of a relatively new infrastructure to deal with, just like our cars we built roads to fit the cars Europeans built cars to fit the roads, high RPM small displacement, VS low RPM large displacement in US. Power in Europe had to be retrofitted into 300 year old buildings, much easier with higher voltage-thinner wires, if you have ever been over there they also run their plumbing on the outside in old buildings because there is nowhere to put it inside the walls.

I’ve left perhaps the most salient characteristic of the Sony AF55 and A33′s EVF till last: It’s huge. The view through the Sony A33′s eyepiece is much more akin to that of a full-frame DSLR than that of any competing sub-frame model currently on the market. It manages this with a comfortably high eye point (and plenty of dioptric adjustment) for eyeglass wearers, at least when simply viewing the live viewfinder image itself.

While I found enough to quibble about to justify my role as a reviewer, I also found the Sony A55 and A33 to be uniquely compelling cameras. The most telling point was how hard I found it going back to an "ordinary" SLR after just a day of shooting with the A55. I’ve long been an avowed EVF-hater, but the viewfinder display on the Sony A55 is good enough that I found myself sorely missing it when I returned to shooting with a conventional sub-frame SLR with a typically small optical viewfinder. The Sony A55′s shooting speed matches that of professional models costing literally thousands of dollars more thanks to the unique pellicle mirror design, and its uniquely Sony features (Handheld Twilight/Multi-Frame NR and Sweep Panorama modes in particular) take the A55 places no other SLR has gone before. I was also pleasantly surprised by how comfortable the Sony A55′s grip was, given the tiny body size. I still prefer having more to wrap my fingers around, but this is as good a grip as I’ve seen on an SLR body this compact to date. While its primary target clearly is not the entry-level shooter, the Sony A55′s Auto+ mode takes it closer to true "just push the button" simplicity in auto mode than any other camera we’re aware of, enabling novice-level users to enjoy the multi-shot and other Scene modes without having to worry about which to use when. At the other end of the spectrum, for the enthusiast with time to become acquainted its capabilities and familiar with its quirks, the Sony A55 expands the realm of amateur photography further than any SLR to date. In the A55 and A33, Sony has used outside-the-box thinking to deliver a uniquely capable, functional, and well-designed SLR. Hot on the heels of their category-redefining NEX-3 and NEX-5, Sony’s engineers have now likewise redefined what consumers can expect from an SLR.

The place to start when talking about mains-voltage equipment is your bench. We realise you’ll probably be working at your kitchen table or wherever you happen to be, but it’s best to start an article like this with a baseline, of what you really should have when doing this stuff. There are three things we’d consider essential in the mains power system on a mains-voltage bench. An isolation transformer to power the item you are working on if it needs a mains supply, a residual current circuit breaker for the rest of your mains supplies, and an emergency isolation switch for all bench power.

There’s a proper place for a relay and a proper place for a SSR. And I agree this solution should have been a relay.

The nostalgia for “classic” miniature consoles isn’t ending anytime soon, either: Sony just announced today it’s making its own PlayStation Classic console. The tiny PS1 will come with “20 genre-defining titles,” and it’s set to release this December for $99.99. Also coming this winter is the Sega Mega Drive collection on the Nintendo Switch, and the trailer for it was published today.

Depends how far north you are – direct sunlight isn’t required for them to produce useful heat. If you’ve got a months long night then they’re no use though.

Once got electrocuted from a computer monitor though, that a relative thoughfully gave us without a case. I was reaching underneath to adjust the brightness or something. Touched something live. The monitor was on the floor, with the 8-bit computer (a Spectrum). My hand touched the live PCB, jerked away, bounced off the floor, and back up to the PCB again. Eventually my sister switched it off at the socket. Bit stupid really, I wouldn’t let kids near something like that, but…

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’ve had 240v shocks about half-a-dozen times, but the two that I recall were both back in the 80s, and were a) trying to fix a set of disco rope lights whilst they were intermittently working, and b) replacing the panel fuse in my CB PSU that I’d removed and hidden to stop my sister using my rig. Both of them involved my subsequent launching of the equipment across the room, accompanied by some suitable profanities.

The first time I hooked up to HT it was a 32+ inch screen (about 27KV) and it launched me into the air and I landed 4 meters behind where I was sitting. The second time was a 27 inch (about 24KV) and there was a wall about two meters behind me and I was slammed into that so hard that I was bruised in many places.

Your writing is appreciated. It’s good to learn something more than just the U.S. english terminology for things. Also makes for a better laugh (sometimes) at some of the anecdotes written in the comments that one reads in so many places online.
