#ElectroBOOM #TravelAdapter

Hi my sister-in-law is visiting from Australia and I'm kidding she's cool. She brought her special hairdryer from there. That's apparently the only type in existence in the entire universe that does the magic on her hair. The problem is that it runs on 240 volts, and here we have 120 volts, yeah, she's, Australia and while my wife is Canadian, it's because we are all Iranian, of course, but every one of us moved to a different spot in the world the end, maybe I Should do a draw my life or something in my other channel meditation anyway, my sister-in-law ended up in Australia, and now she needs, like 230 volts to run her hairdryer.

What she needs is a power adapter, and so she bought this. Yes, this is an adapter, but it only converts the Australian plug shape into a North American plug shape, and in fact this thing was purchased from China, so it already had an Australian adapter. On top of it, you could directly connect them doesn't matter. All we need is something to convert 120 volt AC to 240 volts.

Of course, I'm not blaming her for not knowing she's a senior planner and project manager. With the background in chemical engineering, I am the electrical engineer. So all I'm asking is to trust me for once I earn my skills from experience. If you also like to learn a new skill or improve it, then click on the link in the description and go to Skillshare, where you can get two months of free service.

In which you can take many of the thousands of classes available more on that later, but seriously the best gift you can give yourself for anybody is knowledge. So yes, of course, we can plug this into the hundred 20 volt AC line and it will turn on, but at half the voltage we only get a quarter of the power out of it, so it won't heat or blow enough. Of course, there are tons of electronics out there that come with their own switching power supplies like a laptop or a mobile phone charger that supports the entire input voltage range for these. All you need to do is to adapt their plug, but things like an iron or a hairdryer, don't have their power adapter.

So this is a transformer that outputs 240 volts. You simply plug this into the 120 volt and plug your hairdryer in and turn this on. Oh, this could only output a hundred watts, but this needed a thousand watts. There are thousand watts 240 volts step-up transformers.

You could buy what for that price. You could buy a whole new hairdryer. You can borrow our hairdryer, you know, I don't need it. The only one that does it for you, a you know, you just look fine.

The way you are, I'm sure we can find something similar. No, I didn't buy my degrees, I know how to make it work right. Fine, Hey! Actually, we do have 200 volt or 240 volts AC at home. In North America we run most things at 120, volts AC.

What we also do realize that for very high power stuff, like a laundry dryer or the electric stove running them on 120 volt AC would draw tons of current. So those things run between 220 volts phases at my home 120 degrees apart to make around 205 volts ac. So for the same power it means half the current I heard at some homes they invert one phase 180 degrees to make an actual 240 volt AC. Is that true question mark I'm in a house now that's being renovated? Let's check the voltage here.

The meter was on current always make sure it is on voltage before you measure voltage. Hopefully you can still measure voltage. Oh there you go. You have 240 volt AC, which means our hundred 20 volt.

Ac lines are hundred eighty degrees out of phase, so it is true, they wire the houses differently than the apartments. What's going on here, I hear some electric hissing and arcs what the hell is going on here. It seems like they've, cut a piece of wire here and the water dripping from that pipe cut into that hole and the wire is shorting. This might set the house on fire.

We have to do something about it, so we have from the kitchen. Water is dripping. I opened this, so the water gets out and the wires should be down here I'll, try to pull it out before it burns anything here. I found a wire and pull it out of the ceiling.

I think I need to do something about it. I wish I know which fuse was connected to this guy. Oh, I guess, when the universe doesn't want the house to burn down it sends me over, so that they discover this short well, I don't have my tools with me to this type of wire, so for now we'll just distract the main fuse jeez. Now, how do I find my way up? Yeah there we go, contractors can come and fix it.

I was lucky to be there and to catch it. Imagine if I just filmed there and didn't catch the issue who would ever believe that it wasn't my fault, the house burned down anyway, I should be able to tap into our oven somehow if I pull it back a little bit thanks to the stupid design of The outlet I can pull it back a little bit and expose the high-voltage lines. Let's see, what voltage we step on stupid, spaghetti down here to clean it up with sketchy tight space anyway. These two are the two phases that are 206 volt different and this one is neutral.

That's 120 volts difference, so it means that our two phases are 120 degrees apart, but this is to tighten dangerous here, so maybe the perfect location for her. I'm joking, of course, I'll break my back trying to pull her body out of there and why do we need to go back there anyway, when we can pull one of these heating elements out, see if I probe it and turn this on, I read the 205 Volt AC here and these elements can run over thousand watts, so this output is pretty adequate. For me, shame I can't plug this directly in there. Well, this is super sketchy.

Well, let's see if it works. Okay, it works. I guess I can wire an outlet here and plug it directly in there to be safer. Okay, here's an idea, I remember for some reason, all the outlets in my kitchen have a separate phase going to every outlet see there.

I think it's because we are running high-power appliances in the kitchen and it's wiser to run them from different phases, not to overload the line. So if I can plug the hairdryer between two phases, I'll be in business, just need some plugs and outlets. Here we are, every wire of the outlet is connected to the live of one of these plugs, and even if we just plug in one of them, it is still safe to touch the other one, because it's not connected anywhere. Now, if we connect the hairdryer, I was wrong if you plug in a hair dryer, that's on the live voltage will travel through the hairdryer to the other plug.

So this is live now. It's only safe if you plug both of them in first and then plug the hair dryer. I just bought a new one egg. I thought this was the Holy works even better.

I did find you the perfect solution. At least, I feel a little bit better knowing that this video is sponsored by Skillshare, a community of people with all sort of knowledge and skills from business, woodworking technology, art, music and more who are willing to share it. There don't forget to use my link in the description to get two free premium months after reach. It's only $ 10 a month on an annual subscription you'll learn your brains out.

I love the fact that the Skillshare platform provides incentive to people with knowledge to come out of hiding and share what they know and to make that knowledge so easily available to everyone in the world two months free. I really enjoyed the introduction to Arduino by Mark front filter. Everybody has been using, Arduino is to control the stuff and I feel like I've been slacking behind. So maybe I should take some more advanced classes there and then maybe we can build something together.

A question mark check them out.

    Did the two phases he used to connect to make them line-to-line were 180 degrees out of phase?

  2. Avataaar/Circle Created with python_avatars Michael Barnstein says:

    Australia's voltage and frequency is 230 and 50 hertz in case anybody is curious.

  3. Avataaar/Circle Created with python_avatars kraftzion says:

    You didn't mention why you have 208 in the apartment. It's because the apartment needs 3 phase power for the elevator motors at least, and might have some other 3 phase loads. So you have 2 legs of 3 phase run to your apartment.

    “Oh hi grandma, it’s me, Charlie Brown. We’re having a Thanksgiving party“
    “Wawa Wawa 😍!“
    “really? Thanks!“ Puts down phone “grandma finally found the power adapter to her turkey cooker, so we can go to her house for Thanksgiving!“

    Yours is an excellent channel! But you never explained why your home has 205-6V while the other one has 240V. It is, of course, because your home is likely an apartment, and many apartment buildings are wired with three-phase commercial AC, which as you mentioned, has phases separated by only 120 degrees, so the two 120V phases don't add up to 240V. Residential wiring, on the other hand is actually split-phase 240V, or 240V with a centertap.

  6. Avataaar/Circle Created with python_avatars Luke Tr says:

    I'm so glad that I have 240 V between N and L1 and 400 between L1 and L2, L2 and L3

  7. Avataaar/Circle Created with python_avatars Taylor McCall says:

    Is it possible to get a transformer to combine the split phases so that we can use a neutral wire in 240V circuits?

    Electrocution by spaghetti noodles is a REAL thing. Thanks for having the courage to expose this risk!

    I am happy that this was actually his house… I was slightly concerned the he either broke into someone house or he got permission to enter someone's house and started to poke holes in the ceiling.

    OK BOOMers!!! I'm sure a bunch of you will be traveling these holidays. May I suggest… LEAVE YOUR $%#@ing HAIR DRIER BEHIND?!!!
    HAPPY HOLIDAYS!!
