content: Telephone, not power.Though if you go to the more slummy parts of the world, you'll find power distributed in an even uglier manner (people -- customers and otherwise -- just tie on wires wherever they want, who needs fuses or grounding?).Tim

content: Yes, of course, thank you.Very low-bandwidth communications system back in the day. I bet they'd have been amazed by fiber-optic lines. Iam.

content: Apologies for the long links, this is what folk in the Middle East and Asia face when it comes to power lines. The phone lines are not a problem because these days most of them have mobile phones.http://l3.yimg.com/bt/api/res/1.2/b_LbzNRCHI39H6Tyefnpcg--/YXBwaWQ9eW5ld3M7Zmk9ZmlsbDtoPTQyMTtweG9mZj01MDtweW9mZj0wO3E9NzU7dz03NDk-/http://media.zenfs.com/en_us/News/ap_webfeeds/50c8074911a83c19580f6a706700b6a2.jpghttp://l2.yimg.com/bt/api/res/1.2/8zk6LHa3OWvpATDTMvFZ6Q--/YXBwaWQ9eW5ld3M7Zmk9ZmlsbDtoPTQyMTtweG9mZj01MDtweW9mZj0wO3E9NzU7dz03NDk-/http://media.zenfs.com/en_us/News/ap_webfeeds/9fd2265a11a83c19580f6a706700a072.jpghttp://a57.foxnews.com/global.fncstatic.com/static/managed/img/fn2/feeds/Associated%20Press/2014/06/27/0/0/Mideast%20Lebanon%20Shatila%20Electrician-6.jpghttp://www.themijachronicles.com/wp-content/uploads/2010/02/img_7216.jpghttp://anthrome.files.wordpress.com/2010/05/img_2510.jpghttp://media.kickstatic.com/kickapps/images/21864/photos/PHOTO_8103256_21864_3955394_ap.jpg

content: German_EE:Wow! Those are horrifying. It's a pile of wires in the sky!I wonder if those places have no Code to adhere to, have a loose Code, or are simply ignoring Code? Those must be a nightmare to fix when something fails.Here in the US, we (sadly) still do overhead power lines (some of which fall down every storm) but nothing like that.I took a tour of a WWII Iowa Class Battleship once (USS New Jersey) and was amazed at the wiring conduit looms running through all the corridors.These, in fact:http://home.comcast.net/~bzee1a/USS_NJ/DBZ_5408.jpg. But those are all neat, organized and accessible, whichwould still require a lot of training to sort out. Those Middle East ones look like the sort of thing where the only person who can fix it is the one who put it there.BTW: The guy who took the battleship picture seems to have taken the same tour I did. Nice camera work. They should let Dave or Mike in there with a screwdriver.http://home.comcast.net/~bzee1a/USS_NJ/USS_NJ.html

content: Yes, but this one was designed to be serviced while in use, so nothing is glued and welded shut that needs to be openable. You can even repack seals on the main drive while it is running with only a drop off in speed.

content: Quote from: SeanB on September 05, 2014, 04:30:38 amIf you are referring to the cable trays, that not quite the case. Where ever they run through a fire bulkhead the hole is packed with fire-proof cement and I can tell you from personal experience it's a bitch to clear a hole for new cable runs without damaging existing cables
