    Domestic Electrical Wiring

    in The Electrical Forum

    Posted

    The complete draft of the new IEE 17th Edition is still available for download at http://www.iee.org/Publish/WireRegs/DPC/index.cfm

    Well spotted sir, downloading now, a little 'light' reading :o

    Interesting to note that it will still be called The IEE Wiring Regulations although the IEE changed its title last year to the IET (Institute of Engineering Technologists), bloody stupid idea (which I voted against), "IEE" is a well known 'brand' which is why my business cards still carry the 'MIEE' designation as well as 'MIET' (nobody outside the institute has heard of the IET).

    [a] For Australia, 230/400 V +10% −6% (in accordance with AS 60038); and

    For New Zealand, 230/400 V + 6% to −6%.

    So, Oz is now harmonised ready to join Europe where you belong :o

    All we have to do now is persuade the Septics to join the 230V 50Hz club along with the Japs (100V 60Hz IIRC) and the Philippines (220v 60Hz). The Philippines is somewhat special, in that their 220V is actually between phases (so both wires bite), means all MCBs, switches etc. have to be double-pole, pain in the XXX. Also the only country to use 220V 60Hz.

    Grounding The Roof Structure

    As I suspected, lightning conductors would be overkill or even hazardous, not going to bother, there's a massive Wat next door anyway if lightning's going to hit anything 'twill be there. Pukka MOV going on the incoming supply.

    I'm just a little concerned at having a large mass of metal that's effectively isolated from deck with the possibility of it building up a dangerous charge (during a storm maybe), maybe a length of 10mm2 down to a standard ground stake for each framework will give me peace of mind.

    I have zero experience of this type of structure (UK roof structures are usually wood), always smart to interrogate the collective knowledge :o

    Grounding The Roof Structure

    in DIY Forum

    does rebar when installed in a house make a good ground?...has anyone tested it the official way?

    No (certainly not as part of an electrical installation), for two reasons :-

    1. There is no guaranteed electrical path from the bit of bar your roof is attached to down to the bottom of the support pillar (tack welds and wire twists don't make good conduction paths).
    2. The re-bar in your foundation should not be in contact with the ground it should be totally encased in concrete, which if not damp, is a pretty good insulator.

    Toothbrushes

    Yep, the b00dy things breed in our bathroom too and there's only me and the missus in the house.

    And, it's not only Thailand, here in Manila the office washroom (male) has a communal mug with about 30 (seemingly identical) toothbrushes all in various states of wear which are used by the male staff, I assume (probably wrongly) that each has 'his' own brush, toothpaste is provided by the office cleaners along with the soap and bog roll :o

    Incidentally, we also have a plague of wire hangers breeding in our spare bedroom closet.

    Grounding The Roof Structure

    OK, we're finalising the drawings for our retirement home. Standard Thai construction, concrete with a welded steel roof structure under clay / concrete / ceramic tiles.

    Common sense says I should ground the steel, so how, individual stakes (we have three isolated roofs), common bonding with a single stake, do we tie these structures to our mains ground? How big a ground cable should we use blah blah.

    Any point having lightning conductors?

    Any and all suggestions considered :o

    Being a poor consultant and only having a lowly Ford Ranger (with the mp3 player). I record "Steve Wright in the Afternoon" off BBC Radio 2 using ReplayAV. Burn it to CD and listen to it in the traffic on the way to the office next morning. Oddly enough the traffic flashes fit quite well (slow queues). :o

    As for single phase voltages, Australia is 240 volts RMS, Thailand is 220 volts RMS & UK is the same as Australia (or is it 230 v? Correct me if I'm wrong Crossy).

    UK WAS 240V +-5% until a few years back (2000 ish), then with European harmonisation the nominal voltage was reduced to 230V (Europe increased from 220v to 230V), BUT the tolerance on the 230V is sufficient that both 220V and 240V are in range, so in reality sod all has changed, UK=240v, Europe=220V.

    The Euro-politicians also tried to impose the 16A Schuko plug on us too, but issues with ring mains and the whole nation needing re-wiring as radials killed that one off :o Although, just like Thailand, some major appliances come with Schuko plugs attached which the installation man must replace by UK standard.

    Airline Pilots And Control Tower

    in Jokes - Puzzles and Riddles - Make My Day!

    Posted · Edited by Crossy

    Suegha has started something here :o

    Let's see how long we can kee the oldest thread in the jokes section of the front page, airline related gags only of course :D

    These haven't been posted for a while :-

    ========================

    All too rarely, airline attendants make an effort to make the in-flight "safety lecture" and announcements a bit more entertaining. Here are some real examples that have been heard or reported:

    ~~~~~~~~~~~~~~~~~~~~~~~~

    On a Southwest flight (SW has no assigned seating, you just sit where you want) passengers were apparently having a hard time choosing, when a flight attendant announced, "People, people we're not picking out furniture here, find a seat and get in it!"

    ~~~~~~~~~~~~~~~~~~~~~~~~~

    On a Continental Flight with a very "senior" flight attendant crew, the pilot said, "Ladies and gentlemen, we've reached cruising altitude and will be turning down the cabin lights. This is for your comfort and to enhance the appearance of your flight attendants."

    ~~~~~~~~~~~~~~~~~~~~~~~~~

    "There may be 50 ways to leave your lover, but there are only 4 ways out of this airplane"

    ~~~~~~~~~~~~~~~~~~~~~~~~

    As the plane landed and was coming to a stop at Ronald Reagan Airport, a lone voice came over the loudspeaker: "Whoa, big fella. WHOA!"

    ~~~~~~~~~~~~~~~~~~~~~~~~~

    From a Southwest Airlines employee: "Welcome aboard Southwest Flight 245 toTampa. To operate your seat belt, insert the metal tab into the buckle, and pull tight. It works just like every other seat belt; and, if you don't know how to operate one, you probably shouldn't be out in public unsupervised."

    ~~~~~~~~~~~~~~~~~~~~~~~~

    "In the event of a sudden loss of cabin pressure, masks will descend from the ceiling. Stop screaming, grab the mask, and pull it over your face. If you have a small child traveling with you, secure your mask before assisting with theirs. If you are traveling with more than one small child, pick your favorite."

    ~~~~~~~~~~~~~~~~~~~~~~~~

    "Weather at our destination is 50 degrees with some broken clouds, but we'll try to have them fixed before we arrive. Thank you and remember, nobody loves you or your money more than Southwest Airlines."

    ~~~~~~~~~~~~~~~~~~~~~~~

    "Your seat cushions can be used for flotation and, in the event of an emergency water landing, please paddle to shore and keep them with our compliments."

    ~~~~~~~~~~~~~~~~~~~~~~~~

    "As you exit the plane, make sure to gather all of your belongings. Anything left behind will be distributed evenly among the flight attendants. Please do not leave children or spouses."

    ~~~~~~~~~~~~~~~~~~~~~~~

    And from the pilot during his welcome message: "Delta Airlines is pleased to have some of the best flight attendants in the industry. Unfortunately, none of them are on this flight!"

    ~~~~~~~~~~~~~~~~~~~~~~~~

    Heard on Southwest Airlines just after a very hard landing in Salt Lake City: The flight attendant came on the intercom and said, "That was quite a bump and I know what y'all are thinking. I'm here to tell you it wasn't the airline's fault , it wasn't the pilot's fault, it wasn't the flight attendant's fault, it was the asphalt."

    ~~~~~~~~~~~~~~~~~~~~~~~

    Overheard on an American Airlines flight into Amarillo, Texas, on a particularly windy and bumpy day: During the final approach, the Captain was really having to fight it. After an extremely hard landing, the Flight Attendant said, "Ladies and Gentlemen, welcome to Amarillo. Please remain in your seats with your seat belts fastened while the Captain taxis what's left of our airplane to the gate!"

    ~~~~~~~~~~~~~~~~~~~~~~~

    Another flight attendant's comment on a less than perfect landing: "We ask you to please remain seated as Captain Kangaroo bounces us to the terminal."

    ~~~~~~~~~~~~~~~~~~~~~~~~~

    Part of a flight attendant's arrival announcement: "We'd like to thank you folks for flying with us today. And, the next time you get the insane urge to go blasting through the skies in a pressurized metal tube, we hope you'll think of US Airways."

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Heard on a Southwest Airline flight. "Ladies and gentlemen, if you wish to smoke, the smoking section on this airplane is on the wing and if you can light 'em, you can smoke 'em."!

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Have a safe journey, wherever you're going............

    Electric - Clarification Required!

    in DIY Forum

    Posted

    But as for using this system without the prescribed 'fused plugs', I think it could be dangerous...especially if the protective device is say 32 Amps (3 times the current rating of standard appliance flexible cable) & if fault current limitation is not provided (if required) at the incoming supply of the installation (HRC fuse).

    No doubt it can save on material & labour costs but I think if it is going to be employed, it should be done so according to the standard after the standard has been normalised to the country where the system will be installed.

    All points agreed 1000%, our OP has reduced his breakers to 20 or 25A :o

    It may also be an idea for him to split each ring into two radials each on a separate breaker, that would avoid confusion later when a local sparks looks at the system ("wot's a ring main boss???").

    Interestingly, the UK regs have recently (10 years or so) been changed to permit radial installations in industrial premises, 2.5mm cable on a 20A breaker or 4mm on a 32A (IIRC).

    Retired American Overstay On Mutiple Entry O-visa

    in Thai Visas, Residency, and Work Permits

    Posted

    Hmmm, with a small overstay, I would say he'd be fine, no loss of visa, pay the fine, fly out, fly back, get another 90 day stamp :o

    I have no idea how immigration at the airport will react to a 3 month overstay. Probably also no problem, anyone got any first hand experience?

    Rule number one - do not overstay your entry stamp.

    Rule number two - Do check your entry stamp before leaving the immigration desk.

    5 Years Driving Licence With Only 1 Year Of Visa ?

    in Thailand Motor Discussion

    Posted · Edited by Crossy

    Since the longest visa commonly available is 1 year, and many many Thai Visa members have 5 year licences it is of course possible :o

    I got my 5 year with only about 50 days of my Non-o remaining :D

    EDIT My licence now outlasts my PASSPORT, the nice lady at the licence office suggested that I keep my old PP so they could find the reference easily.
