How to Get 220v From 110v

hey guys Bruce here with DIY homestead projects I'm going to show you how I'm gonna hook up my 240 volt welder in a shop that does not have a 240 volt outlet a while ago I did a video and I I put in several outlets that will right above each other I've got one down here with a with a brown cover on it it's kind of hard to see and then directly above it I have another outlet now the whole point for me putting these two outlets that close together is they're on separate lines they're both 20 amp circuits with 12 gauge wire which is 420 amps but I'm going to make a device that is called a circuit combiner I think that's what they call it they do make a commercial device I'm gonna make my own and that's what this video is all about so if you look at an outlet on the bottom you've got the round hole which is the ground the left side is the common and the right side the small blade is the is the hot wire put the black probe in the ground and the hot wire on the small one I can hold them in there where they make contact so hopefully you can see that meter it's showing a hundred and twenty four volts one hundred and twenty three point one so what I have are two outlets on different lines supply lines both supplying 120 volts being on separate lines if I put this bottom one on the hot side of that outlet and the top one on the hot side of its outlet I have 245 volts in this case so combining the two outlets I can get my 240 volts now I know I have to 20 amp circuits there if I build a combiner that will handle 20 amps I should be in good shape and be able to set up 240 volt socket using those two outlets and the reason I put them so close together is so that I can put this box right here on the corner of my bench plug my welder into it or I can use it out in the carport area where I have those other outlets that are right on top of each other and I can get 240 volts out of any of those up to 20 amps I'm going to show you how I'm going to build the box and then I'll demonstrate how I use it so here's the supplies that I have for building this combiner box and there's a couple of companies in the US that actually make these things and sell them those boxes are a little more complicated than the one I'm going to build a lot of times they'll have a circuitry in there to where you can push a button on the box it'll light up if you've got the proper outlet in my case I don't need those features because I know that my outlets are on separate lines because I put them in I know that both of mine are both 20 amp circuits with 20 amp breakers all right so I bought this metal this is an outdoor weather proof box doesn't have to be a weatherproof box but it will work real good in this particular case I bought a couple of extension cord plugins these are 15 amps and then I also have some just standard scrap pieces these are both a foot and a half long of extension cord wire so I know that the gauge in this wire and these plugs are both only rated for 15 amps but these cords are so short they're only a foot and a half I think I'll be fine and I'll put links to this stuff in my description if you're interested in having a closer look at what I got a 50 amp 250 volt plug in and this will go with the plug that I just installed on my small inverter stick welder the bottom one will be a ground and then 2 hots 3/8 inch half inch knockout they go in this box and they will keep the wires secure so they don't pull out [Music] if you look at an outlet and the ground is on the bottom the right blade which should be the skinny blade on the outlet box is the pot wire the left blade which is the bigger slot is the neutral I've wired the green to the ground which is the round one if you look at it this way the upper left is the hot the white wire is not used it's just been completely cut off I cut it off of both ends of my leads here so I'm just using two wires the black for the hot and the green for the ground so make sure that you wire that accordingly when you wire in your plugs [Music] [Music] so I got the ends put on and then I'm just double check and I'm taking my multi mate multimeter on continuity and I'm gonna check the upper left blade should be the black wire and it is just a double check I'm gonna check my ground on the round blade on the bottom and that should be the green and I checked both the cords just to make sure I got them wired properly I've got both of my leads that I built with two wires a ground and a hot wire coming into my box my stress reliefs are clamped down so I've got plenty of wire in the box to work with and then right up here I've removed the screw there's a green screw since this is a metal box it needs to be ground so what I've done is built two bare wire copper leads coming off of this grounding screw so I'm gonna screw this down into the bottom and then I'll pick up from there okay I've got that those two grounding wires screwed down to the bottom so that the case will be grounded and then I'm gonna take both of these green wires coming from my wires incoming and use a wire nut to connect those two to one of these ground wires so this may both ground wires coming in are wired together and then round it to the box which is a must for having a metal box now we have one of these hot wire leads comes loose and touches the side of this box or just touches anything you're not gonna get a shock using this device and now I've got three wires I've got a ground that's coming off the box and two hot wires one hot wire from each outlet and those are gonna get connected to the three leads on this two hots 110 hots on each or 120 in this case and then a ground so let me get that wired up okay there we go one hot goes to one blade the other hot ghosts the other blade and my ground goes to the ground and they're all labeled the two hots it doesn't matter you could put them on either side so let me tuck this all down in there and neatly tuck that ground wire out of the way screw the top on and then we'll be ready to plug this in and do a little bit of testing so let's do a quick test before I plug it in just to kind of confirm that it's wired up properly so I should have ground to the box to the outside okay so the box is ground shouldn't have anything on these so I don't have a short all right let's plug it in see what happens it doesn't matter I just want my cords to be untangled alright nothing exciting yet so that's good news this is basically exactly the same thing that's going on inside the breaker box when you have 240 wired in only it's well it's a little bit different because that's one single breaker whereas this is using two separate breakers to the ground and either side should give me a hundred and twenty volts 124 can you see that yeah you can see that one twenty two point seven on that side one twenty three point one on that side now one thing that's added into this equation is uh one of these circuits runs the lights in my shop so if the lights and the draw of my welder that'll be a test I'll have to do if they exceed 20 amps then I'll pop a breaker so I don't know if that's going to happen or not I kind of tend to think that this little welder isn't going to pull that much power but honestly I don't know so now if I connect both hotlines I should see two forty to forty five point five so I now have a 240 volt outlet why it's a huge plug for such a little tiny welder and we have an on/off switch on the back and the fans on blows through to the front a lot blows a pretty good amount of air yeah we've got the green light on well so far so good now I just need to find out a federal action well there's a couple of safety features or a couple of safety issues that you may want to consider I don't know the answer to them I may do some further testing to find out what the actual answer is but some people say that it's not safe if you have only one side plugged in one one-half splud in and this other side could be live but that's not true there's nothing inside the box that's connect to get together so I wouldn't be concerned about that one other thing that they've talked about is if you have it all plugged in and you have a short or something happens in in the device that you're running if you pull that pull one side out you could be shocked from it because it's shorted through the device or maybe not even shorted or just plugged in and turned on might just might just complete the circuit and then allow electricity to flow to this side but that's a simple fix I'm never gonna I'm gonna plug this in to the wall both outlets and then plug my device into it and before I unplug these from the wall whether something happens to my device or doesn't happen to it I'm just always gonna unplug it from the box first and then unplug these two outlets from the wall last and I I don't think there's going to be any issues with that that way since I don't know the answer to that one if that's true or not that's a that's a simple walk around easy too easy to prevent but you got to be thinking about what you're doing when you're working with it well thanks for watching guys I appreciate it if you have any concerns or comments or additional information something that I did did wrong or or should do better feel free to leave a comment otherwise thanks for watching guys make

Dude needs to seriously cease and desist with this crap.

What a moron

My dryer is pretty small, I'll just plug one of them in

[u/itguy1991]

Serious question (based on some assumptions)

If everything was installed correctly, meaning;

-Both outlets are fed with 12ga wire -Each outlet is the only thing on the circuit -They share a neutral, and thereby are on a double-pole/single throw breaker (sorry if that’s not the correct term) -12ga Extension/SJOOW/SOOW cable is used -proper/quality plugs/receptacles are used (maybe even L5-20) -proper clamps/strain relief is used on the combined box

Assuming all of that, and a proper sized load like a 20A/240v electric car charger, what is the danger in making something like this?

(Ninja edit: by the time you do all that, it would probably make more sense to just install an (L)6-20r, just asking as a thought experiment)

holy shit, wait till he has the welder in and one plug out. this is a terrible idea

[u/trompolinihater]

so hes got 240 in the garage but rigs up that contraption! WTF!

[u/WarMan208]

Crazy... this video popped up on my feed this morning. I gave him a good scolding. He even did a follow up video to try justify his stupidity. Something tells me he wasted his time though, we all know this fool can't weld
