I would love to know the PUE on these bitcoin mining centers. I have the pleasure of working in a data center without exposed bus bars and ducts. The one pictured seems like it has limited to no air flow containment, I doubt it is very efficient.

Three-Phase posted:One of the things here - if you were using a real piece of switchgear instead of this cobbled-together (but arguably clean) approach of having the breakers and busbars on a metal frame, you'd probably have better bracing of the busbars themselves. So in conclusion I should change every circuit breaker I have to a Current Limiting Class J Time Delay Fuse? And never buy a more expensive current limiting circuit breaker because it makes no real difference?

Doesn't matter much for household current, since you'll never see more than a few hundred amps, which residential circuit breakers can handle without a problem. The distribution transformers have their own internal fuses in case of a short in the primary.

You should evaluate (yourself or professionally) the maximum potential current that could flow through certain systems and determine if a system that can be reset with the flick of a switch or only with the replacement of a fuse is right for you. Hint: If you have circuit breakers and you follow "lock out, tag out" style procedures you're so so so much more safe than most other systems.

Is there any system out there which is set up to allow you take the fuses out of the circuit as easily as you would flip off a circuitbreaker and is set up for lock out and tag out? Surely that must be reasonably easy to set up?

Outside of some retarded distributed designs its almost always going to be at a switchbox so a common practice is to pull the fuse and lock the switch, which on most boxes locks access to the fuse housing too.

dr_rat posted:Probably didn't have there seat belt on. Seat belts cost lives people! Right, he probably didn't because he was towing a semi and trailer on a snowed to hell road. There was a non-zero chance of exactly what happened happening, chances are he was puckered up the whole time and ready to bail from the truck if so much as a hair on his arm twitched. The way that sucker rolled on its way down I'd bet he was done for if he rode it down, belted in or not. Arrath fucked around with this message at 03:23 on Jun 13, 2015 |

IIRC there was someone in either the passenger seat or in the vehicle he was towing.

So that's how it's done? At least the tree didn't hit the house. My neighbors have a huge tree lurching over our row houses with only space enough for a ladder. I wish them luck with that (don't really care since I rent). This thread is so GBS 1.0: bouncing from industrial engineering seminars to Say Nothing's disasters on parade. Love it.

This guy lost his face in an electrical accident. He's blessed to be blind. And he's getting a face transplant. warning, gruesome even though it's all healed up: https://youtu.be/b7Lg_mNM4bQ It's an ABC interview, but Jesus

Like, I know it's hard to really see 2015 as "the future." But pretty much everywhere you look in regards to technology and medical advances, we're pretty firmly in what used to be sci-fi. Dude can get an electric shock so bad that his face ends up looking like a caved-in hand puppet and we can make him look virtually normal, at least normal enough that you would pass him on the street and not notice anything unusual.
