They can't pronounce on them, but you also don't want a EMT or fireman or whatever putting themselves at risk of being injured if it's very clear to all bystanders that there is no head attached to the torso. Well trying to save someone at your own peril is foolhardy anyway. The first thing they teach you in pretty much any level of responding is to survey the scene. If it isn't safe for you, don't go and add yourself to the count of people needing to be saved.

dreamin of semen posted:I like to design GUIs I write firmware on what is essentially a life support medical device. We have an entire team dedicated just to making the UI dev's life miserable finding infinitesimal little bugs. Like on some certain screen the right line of pixels is cut off a column of numbers, or the hue of red isn't consistent across menus. Yea they find real bugs, but holy poo poo I'm glad I don't do UI dev. Pretty much everyone leaves the backend people alone and we make sure our poo poo works and there isn't reason to complain... My original point is that the backend should ultimately sanitize stupid inputs and not break in a dangerous way. Even if a lovely UI allows someone to enter stupid data, enter it in a bad order, lean up against something and accidentally do whatever, the back end should be robust enough to not screw up. I think the thing I hate most about UI dev is that it doesn't matter what you do, it won't be intuitive to 1/4 of the users and they'll hate it. no matter what. chrisgt fucked around with this message at 01:51 on Dec 5, 2019 |

There is over 100vac between two laptops on different outlets in my house. This is safe, right? Turns out none of the outlets are grounded; there's an miltiwire branch circuit in the basement and some of the outlets have 120v between the neutrals... I'm lucky I haven't let the smoke out of anything or killed myself with this poo poo...

Cojawfee posted:If they are on different circuits, that is totally normal. The power company sends ~240v to your house split between two phases. Every other breaker in your breaker panel is on the same phase and gets 120v. Double wide breakers are on both phases and can get the full 240v. It's a miltiwire branch circuit, so yes I get that. However you shouldn't have 120v between TWO NEUTRAL CONNECTIONS. You will see 240v between two hots on different legs, THAT is normal.

Elviscat posted:Oh yeah, that's a classic open on a shared neutral, turns the whole shebang into a series/parallel circuit between the two 240V legs, dropping voltage across each one according to the load. The only reason those laptops aren't smoked is the magic of switch mode power supplies. It's not my house, I just rent. I pulled the offending outlet and put the correct wire to neutral and hot. Now I have 0v between neutrals and 240v between hots. There is nothing at all hooked up to the ground pin, not even a jumper. Although I think it's technically to code to convert two-wire installations by putting a GFCI with a jumper between neutral and ground. There IS a ground wire, but someone cut it off flush with the box, so I'd have to pull the box out, see if there's any loose wire in the wall (there isn't) and then splice in a new piece. Why they did this is beyond me. None of the outlets in the entire house are grounded. Not a single one. Not even the GFCIs in the kitchen and bathrooms....

Slanderer posted:The ground fault itself is tripped just due to current imbalance between live and neutral, regardless of what path the return curent takes instead of the neutral. It's not quite the same without the ground, especially with regard to EMI, but I dont know the specifics Yea, I was under the impression the outlet monitored the ground current and tripped if it was too high. For that I assumed there had to be a bond between ground and neutral (hopefully in the distribution panel...). But I have never taken one of these things apart to see how they work. I should do that.

Facebook Aunt posted:I like how so many of the burned out cars turned immediately rusted out. Ocean is OP. Fire and rust are actually the same process, oxidation. Also fire removes paint, galvanizing, and the tempering from the steel, further letting it oxidize. If you burn a car in arizona, it'll turn up immediately rusty like that as well.

I used to clean a lot of gutters (anything to make a buck). I'm not surprised by this at all. I have pulled entire saplings out of gutters. Like 6ft high trees with roots in the downspout. Throwing it onto the walkway was a bad move, though. That's going to be a real pain in the rear end to clean up. I've installed a lot of patios/walkways like that with pavers, they are NOT easy to clean that kind of gummy dirt out of. I'd always have a tarp with a wheelbarrow on it. Target for the barrow, but hit the tarp if i miss, avoid a ton of cleanup.

stevewm posted:I had something like this happen before... I rented a house like this with missing grounds, I couldn't be barefoot at my metal desk. If I stood barefoot on the floor and held one meter probe in my hand, the one touched to the desk read 60vac. I don't think it's because anything is leaking current to ground, if that was the case your monitor would trip a GFCI if you plugged it into one. It's because the three-wire plug for your PC, monitor, etc., has, basically, two hots and a ground all parallel to each other. I say two hots because there's no concept of neutral if you don't have a ground. The result is that through capacitive coupling the "ground" wire picks up 60vac. Now you have 60vac floating on everything that should be grounded, thus touching the USB ports or HDMI cable or something and also touching the actual, physical ground, will give you a shock.

CarForumPoster posted:What? The three prongs have a neutral that should be 0V relative to earth ground and a hot thats 120V and a ground that’s 0V unless you’re part of a voltage divider you’ll never be 60V. Well the discussion was that the outlet did not have the ground wire connected. Therefore the ground wire in a cord becomes floating. And if any energy is induced into this floating ground wire by ground leakage in equipment, the fact that wires next to each other capacitively couple, EMI/Y caps, etc. you'll see voltage on the ground. Thus you may see voltage between the equipment case and the actual, IRL, ground.

He grabs the load before it makes any grounding contact, can't this lead to extreme static electric shock, or is there some other mitigation to that?
