  1. Re:Coincidentally... on US Electrical Grid On the Edge of Failure · · Score: 1

    Generally, 2.5mm^2 Twin & Earth cable is used on ring mains as this is suitable for short runs (ie homes), for longer runs or where a single appliance (eg a cooker or a shower) occupies the circuit due to power demand, 4mm cable is used. 2.5mm cable is normally rated for 240V@20A but because of the setup the circuit is rated at 40A, the ring main is fused at 30A.

    You didn't understand my post at all, did you? I'll admit: I'm a 'field expedient' electrician* without formal training, but I've read the codebook. If you tried to run a ring circuit here in the USA the inspector would look at you like you're crazy.

    The concern is that if you have a ring circuit, you can no longer de-energize the boxes by disconnecting a single set of wires. In addition - 2.5mm cable is rated for 20A. In a ring circuit they 'rate' it at 40A but have you put a 30A breaker on it. Now the NEC presumes people are idiots. Or at least the people who are most at risk for the fires, electrocutions, and shocks they're trying to prevent. The concern is that you have some idiot working the walls and he cuts through one of the ring wires. Because it's a 'ring', you now have two radial branch circuits hooked into the same breaker, each with a max of 20A. It's 'probably' fine if they were cut approximately in the middle, but that's not guaranteed. So let's say all the boxes ended up on one branch. Now you hook up a 30A load to it - where the wires are only rated to 20A in this configuration. Trouble!

    As such, in the USA running multiple sets of lines to power a device is seriously frowned upon; you are to use the right size wires, not multiple runs of smaller wires. You don't run 2 lines of 14 gauge wire for a 20A circuit, you run 1 line of 12 gauge

    Then again, rereading your original mention of it, maybe I'm missing something: Are we talking about the wiring inside the walls, or in the cord hooking the appliance up to the wall? I was looking at the wiring inside the walls, because that's what came up when I searched for your terms.

    The earth pin, for instance, on the plug is thicker and longer and rotated 90 degrees with respect the other two pins.

    It's not like this is magic, for example the more modern US NEMA connections also feature an earth pin that is longer, except it's circular vs being rotated. Because we don't always require the circular ground pins, for appliances where keying matters, we make the neutral blade wider so you still can't plug it in backwards.

    Finally, on the shielding - while our smaller connectors make foreign object intrusion less likely(most butter knives won't make contact, for example), shielded outlets are available as you mention.

    as opposed to radial wiring which is prone to single-point failure not to mention a fire hazard.

    References on this? Because my reading indicates that it's probably more of a electrocution hazard than it saves on fire hazards - and given that at least part of the fire hazard is 'Idiot drills the wire', a ring circuit is actually more likely to cause a fire as well. Plus, well, it says in the wiki that it was used to save on copper, so a ring circuit has each connector using less wire - so if said idiot cuts one of the lines, he may not know because his outlets are still powered, but now the breaker is oversized for the capacity of the circuit, leading to overheating and fire hazard.

    Remember that nobody is altruistic in this politicosphere. The US will want Syria for only strategic value.

    Can you identify the strategic value of Syria?

    As for actual intervention, it's been my impression that the White House WANTS to stay 'hands off'. While it doesn't particularly like Assad, the rebels consist of a lot of fighters that are even less in the US's interests(though not all). So funneling them guns would actually be contrary to US interests.

    Roughly speaking, we'd prefer Syria be stable(good for everyone), but it's like a match between two teams that we don't particularly care about. As such, it falls to other hot-button topics like NBC use, human rights violations, and such to pick a side.

    You make some good points about a 'heavily' contaminated environment, but my point would be that for the most part you can avoid said areas.

    Hardly. We have a lot more options than just (invade | do-not-invade). We can help the refugees for one.

    Certainly. Which is why I said 'depending on our actions' as opposed to 'invade or not'.

    Right now this smacks too much of "wag the dog".

    To me, hardly. This is a situation that has been brewing long before the NSA leaks and Obama has been mostly sitting on it period - and remember that he hasn't actually announced anything about the latest situation. This is a reporter making a story about standard military actions:
    1. The CIC has made certain policy statements concerning actions in specific circumstances
    2. It appears that the 'specific circumstances' has occurred. Ergo the DoD, in line with the policy statements, is presenting the president with a set of options to fulfill those policy statements.

    This is a reaction to a foreign event. NSA activities are being shoved into the background by the standard newsflow, no 'wag the dog' needed.

    The problem with that is that it is just as easy to kill thousands of people with regular bullets and bombs as it is with chemical weapons.

    What a coincidence, I just had a chemical warfare exercise yesterday. As the AC and geekoid mentions, there's operational differences between chemical weapons and regular ones. It's my personal opinion that chemical weapons make a more effective weapon against civilians, both terror and effective, than it does against prepared military forces. Bullets and bombs still work against a prepared military, while chemical attacks are reduced to a mere annoyance by protective equipment.

    It's not going to deny terrain or soften a hardened target occupied by military personnel ready for chemical attack. Especially hardened targets will likely have the filters and systems to keep contamination from penetrating the facilities.

    And that gets back to it being just as easy to kill people with bombs and bullets as it is with chemical weapons.

    Why do we care so much that it is *CHEMICAL WEAPONS* as opposed to *BULLETS*?

    Cultural perception is that chemical weapons are worse than bombs and bullets.

    Why would we not want to get involved if 10,000 people are killed by bullets? But 100 people killed by nerve agent and we're in an uproar?

    It's more that 'more than 10k people have already been killed by artillery and small arms fire; now they're adding in chemical weapon attacks'. They're upping their 'game', much like how more Japanese died from conventional and fire bombs during WWII than both nuclear bombs, but it's the nuclear bombs that get 90% of the attention.

    I guarantee that we will kill/cripple more civilians in a war than they have killed/crippled with chemicals.

    True, but would we match their combined count? They've already killed a lot with conventional weapons. There's still motive to intervene even when the slaughter is mostly knives, there's motive when it's only conventional arms, but for some reason NBC has special meaning on the political front. Obama has made that distinction, not I.

    Reasoning: Liquids tend to keep their temperature more stable than solids. Tanks tend to not be well insulated(if they are, get a more sensitive sensor). Temperatures vary through the day, but the liquid shouldn't change much. Ergo if you point a infrared sensor at a tank, you should be able to easily draw the water line.
