    Rather well designed for their age. Most installations here in AUS were still using rewireable fuses at the time. Or the dreaded plug in CBs that home owners could pop over an existing ceramic fuse - often with one of an inappropriate rating.

      Which I still see in a lot of installations. Found a 32A on a power circuit less than a month ago

    They are made by Weber. They were also used in hungary, that's why I know.

      Amikor kicsavartam őket, akkor mindig ahogy lazítottam, akkor eltörtek. Főleg falukban. A manáéknél még mindig olyan van 6 amperosba. Egy hete nála voltam, mert összehívtuk egyet a családot, ő meg fölment porszívózni, azt mikor bekapcsolta, szokásosan kib.....ta, lement fölkapcsulni, de látta hogy el volt törve. Tehát olyan szinten oldott ki, hogy belerepedt. Amennyire hülyén hangzik, így volt. Na mondom fasza. Azt cserélhettem ki. Futottan haza hoztam egy vadi új bakonyit dobozban, sajnos csak 6 amperosat, mert oda más nem lehet, azt ki kellet cserélnem.

    The magnetic trip mechanism also has an adjustment screw seen in the bottom right corner at 11:10 and accessible via a hole which is hidden under the label.

    Is the coiled copper strip (rather than wire) on the electromagnetic in order to handle the high current, or is it just cheaper to make that way?

    • @dd313car
      @dd313car 3 роки тому +3

      Its a very flexible wire which is needed there bcause of the movement of the mechanism. You can't use solid or normal flex core it wold be too stiff.

    Mr. Ward, I have a question. Why are toasters legal? I mean they are IP10 devices that are just... everywhere. Does every consumer-reachable electric installation and device must be more than that (except toasters?)

    • @Seiskid

      Grandfather clause. The design pre-dates modern regulations. Same as the traditional light bulb socket. No way that would get approved today but both are an established design used all around the world and it's just too hard to eliminate. Even as a child most people are quickly taught not to stick your fingers in either. And in more recent times RCDs have helped mitigate the risk with both. The other big issue with the toaster is even after 120 years no one has managed to invent a safer replacement machine that's any good at cooking toast.

      Now there are alternatives, like GU10 and similar which are a bit better.

      Good question. There is no reason why they couldn't put a grounded steel mesh screen between the heating element and the 'cage' that holds the bread. That way, you can't poke the heating element with a knife anymore, and the tines of a fork would be contacting the grounded mesh and tripping the GFCI instantly.

      Toasters are connected only when the tray is down. I do not get why anyone would stick something there.

    Hello Mr. Ward. Your videos are very usefull and clearly structured. Can you please adress 2 topics? First: measuring devices, what festures to look for in a ZE measuring device (for a beginner), insulating resistance tester and for a RCCB / BO tester. Second: differences between types of RCCB / RCBO devices (A, AC and other types). If i missed your videos on the topics above, sorry!

      Really? They are using that _'exact'_ term in the UK as well, like here in Canada regarding snap lockdowns? Hmm. Things seem to be too orchestrated planet-wide. I thought it was odd how many country leaders are _simultaneously_ using the slogan "Build Back Better".
