ParticipantThey were (AFAIK) high enough to only be reachable by non-man-portable long-range SAMs. i.e. truck-mounted or fixed SAM sites. The most recent transport shot down was above 20,000 ft when hit.
Flying through airspace where SAMs capable of reaching to your cruising altitude are in active use doesn’t strike me as a terribly bright idea. But hey, if you want to try it, it’s your life 🙂
Participantdumbrenter: an active war zone. Meaning that planes flying at cruising altitude had been shot down over the past week!
Participantlivinincali: I don’t actually give a damn who did it. My point is that flying a commercial flight over an active war zone where SAM sites are known to be in use is a breach of the airline’s duty to keep its customers safe.
ParticipantThe Ukrainian air ministry issued a warning about their airspace as early at July 8th. Our FAA warned about the same region as well.
Two transport aircraft flying at altitudes higher than those that shoulder-launched AA missiles can reach were shot down over eastern Ukraine before today. People with half a brain or a heart could have put 2+2 together.
Yep. Let’s fly over a war zone where long-range missiles are used to shoot down aircraft. Very smart.
ParticipantOf course. It’s also possible to take a less direct route and cancel flights until one is created if the most direct route is unsafe. Inconvenienced passengers are better than dead ones.
ParticipantI wasn’t speaking to dissimilar metal corrosion, only to corrosion due to the pipes being used as ground. It shouldn’t be significant since current flowing through ground is normally zero (and A.C., not D.C. if there is one).
OTOH, using piping as neutral return would probably yield amusing results.
BTW – I’ve seen the videos of people being hooked up to work on H.T. lines from a helicopter — that takes some serious cojones! Thanks for mentioning that again. And you’re basically right about everything electrical you’ve posted here — are you an EE?
ParticipantI think I need to donate to an anti-IKEA lobby. I like cheap real estate, not boom times 🙂
ParticipantI think that when the pipes became copper, things change. You can cause current based copper erosion from galvanic action.
Practically, it should be a non-issue since ground shouldn’t have (significant) current flowing through it under normal operating conditions. Yeah, I know some timers and things like that can use it as a return path, but it’s rare.
Participantucodegen —
Correct on all counts.
As to double insulation, you’re talking about a device with a plastic case and with insulated connections inside. Coming in contact with a hot is extremely unlikely, so a ground isn’t needed.
Why do you get a shock when coming in contact with a 120V hot whilst wearing rubber shoes? The amount of current required to shock is very small, and no insulator is 100% perfect. Capacitative effects might also play a role. But I suspect it’s more the former than the latter.
ParticipantSellers can balk. Move on to the next. It costs little to make an offer and you can make as many as you want 🙂
ParticipantWhat’s wrong with raising kids in an apartment? It’s done all the time throughout the world — living in an apartment isn’t a case of leprosy 🙂
ParticipantSD Realtor: the Good Lord made ignore lists for a reason. Feel free to add me if you don’t enjoy my posts, thanks.
I don’t mischaracterize neighborhoods. I just characterize them according to my opinions, as do we all:
(1) I’d never live in a single-family home in an HOA-infested neighborhood. I like to weld/fabricate, work on my car, ride motorcycles, and other things that an HOA probably wouldn’t find socially acceptable.
(2) I want to not be able to walk places (not everywhere) without a needing a car to even leave my development.
(3) I don’t mind “interesting characters”. As a rule, if you don’t bother them, they don’t bother you.ParticipantI never asserted that breakers are primarily for shock safety. Next time, please read the post you’re responding to before you misquote me.
As far as grounding, the power company equipment doesn’t care whether it’s putting 10A through a load or an additional 50mA through a human body. The grounding is there so the latter situation is less likely to arise. If a hot wire shorts to the case, breaker will trip vs making the case hot. If breaker doesn’t trip, the case will still be grounded. GFCI makes the latter situation EVEN less likely to arise.
I already explained why sharing a neutral and ground wire is a bad idea.
Face it: you’re wrong this time. No shame in admitting it.
ParticipantFor you… I have no problem being condescending as you are quite frequently rude and condescending yourself. So little man take a look in the mirror or blame it on being a New Yorker.. I really don’t care.
First of all — … and the horse you rode in on. Good, now we have that out of the way, putz.
As for you argument about circuit breakers I am going to split hairs here.
Second of all, I never made an argument about circuit breakers being life-saving equipment (other than fire-prevention). Sduuuuude did. I actually AGREE with you that GFCIs are for shock safety and breakers are not. And actually, it takes less than two amps (TSOR says a few milliamps in the wrong situation) to be lethal.
PS – Are you arguing just to argue or something? Really confused!
PPS – Drunken posting is typically regretted the next morning… -
