    Rewiring a Lamp

    Hope this thread is OK here.
    OK, I have two lamps, one from the UK (220 and need 110 or vice versa; fek, I dunno these things) with one bulb thingie and a bronze antique one with three bulbs from my Dad that still has the original wiring (ie, that old fabric kinda cord).
    Should I just go to the shop and ask for the wires, take them apart, put the new stuff in and see if they work? What do I need? I have small pliers, so wire and those plug things? I think the three-bulb one may be more difficult.
    Any suggestions most appreciated.

    unless you're handy jet leave well alone. if the old one is brass, an earth wire would be safe/prudent.ie, 3 core flex. without seeing it/them not a lot i can say. better get a spark.

    ^ Thanks. Daveboy, I don't need to change the cords for the 220 one? For the oldy, I definitely need to change the wiring.
    I know, I can send it to a shop, but I like to do stuff meself -- always something new to learn.

    Correct bulb holder, bulb and plug are all that are required.

    But you should take it to a sparky Jet.

    I wouldn't trust a woman to put two AA batteries in a torch the right way round.

    Sorry, but that's how it works out.



    PS it would be more appropriate to change the wiring from 110 to 240 if you were converting the opposite way.

    But going 240 down to 110 should not be a problem.

    ^ Bladdy men. I fix the washers, the pipes, do the lightbulb changes, take apart the stove with my Swiss army knife to clean it, clean the eaves, check the car oil. Bear carves the masks and statues.
    How hard is a bladdy lamp?

    They're the same. Just change the bulb & plug to one of you non-safe ones.

    Other way around.
    The same wattage will draw twice the amperage on 110v so heavier wiring is needed.

    In this case it's only a bulb so the old wire should be good enough

    V = R x I

    220 = 1 x 220
    110 = 1 x 110

    Resistance is constant, voltage is halved so surely the lamp will draw less power.

    Schoolboy physics.

    So resistance is futile.

    5555 You guys are amusing. If I follow Jizzy and Marmers advice, I will be HOT!
    OK, to be safe, I'll go to the hardware shop, maybe take the old lamp, and demand they give me the right parts.

    Jet. I know some people here would like to see you fried. But FFS dont frig around with electrical things. Take it to a licenced electrician and get advice.
    Not knocking any of the posters here who seem to know what they are talking about, just dont think a Thai internet forum is the appropriate place to get advice re something that can KILL.

    Jet if you don't understand earthing , you would be better to take it to a lekrics tard - any device with metal that can be accessed should have a earth wire.

    *grumble, mumble* Alright you two. I'll take it to a shop. Probably staffed with Koreans who know less than I do. Ever see Thai electrics?

    Wise move. An easy job to fix. Will do it for you as you wait. Watch and next time you can do it yourself.

    OK but if the plug is Brit type then she needs to get that sorted. Change or an adapter.

    I think one of them is very old and has the cotton braided flex that went out of fashion soon after WW2,

    ^ And old type insulation on the wires that degrades and crumbles away when the outer cotton support frays and disintegrates.

    But is still fitted to new lamps to give an air of authenticity, and this retro stuff is not the same as the pre-war crap.

    I put in an electrically heated shower, as early mornings can be surprisingly chilly in Thailand. The first thing I did was bang in a copper stake outside and ran an earth lead into the bathroom for the heater.

    As Baldrick said, if it's metal, it should also be earthed.

    I think the thread title should be "How many TD posters does it take to change a lightbulb"

    Which is, as has already been mentioned, all that's needed for said lamps after checking the wiring's insulation first.
