thanks for the help! 1st year apprentice here and this definitely helped me. Appreciate the video
These comments crack me up, typical of people who believe they are now experts in electrical circuits after watching TH-cam. He was clearly successful at achieving his 110v feed without harm. Yeah there's risk but just like he said if you don't have the skills don't do it!
I’ve been rewiring everything from light switches to hot tubs for 20+ years as a G.C. Yea, I’ve seen some sparks fly a couple times, but time is money. And, if I’m working alone I don’t waste my time/money running back and forth to the main, which inevitably will be on the other side of the job.
Totally acceptable rig. Ignore the negative comments. They have clearly never been on a jobsite, trying to get done within bid. I had a similar one for getting 240 off any live source I could find for my welder. Jobsites don't provide outlets. Sometimes running the portable, or chords, or a genny, just isn't an option. Take your time, and be safe. I stumbled on this vid by accident, but was amazed by the negative comments. You're in more danger driving down the interstate, texting.
I have a pump house receiving 230 volts about 70' from my main breaker box. I have an over head light, sprinkler control box and an exterior waterproof 110 outlet box in the pump house. I have used this same configuration for almost 20 years without an issue. Is it code? Got me, but it works. Just make sure you throw the breaker before making the connections.
I do this all the time for the same reason...you gots ta get the job done and time's agoin and once you know what you doing... do it!! ..if you don't then get a pro all yer naysayers!!
I was in at Incerlik Air Base Turkey in 1992 or 93. We hadd a temporary office on the flight line, next to a Tab-Vee or HAS (hardened aircraft shelter). The building we used was a smaller version of the Tab-V, a hardened fire truck shelter. Walls 3 feet thick, hardened with who knows what. It could withstand a near miss of pretty much any bomb, that wasn’t in the nuclear family.
That building was wired for480v 4 phase power.
No outlets. Just the 4 phase plug to plug the fire truck into. I’m guessing here. I know why the HAS would need 4 phase, for aircraft power. But this was a mystery.
We needed to power some equipment. Charge our radios, run our test equipment, yada yada…
We had one guy step up and say, “I can make it work. I’ll take one leg of that power, run it out to a junction box. 120v. Jobs done. No sweat. But it was very hot and humid in the Turkish desert. So there was a lot of sweating 😅
So I’m standing there watching him closely. I just want to see what he does.
So the power comes into the building through the wall, about chest high. It runs into a 1 ft tall by 2 ft wide by 1 ft deep junction box. The safety cover opens from the top, is hinged at the bottom. With a built in stop that makes it stick strait out 90° from the wall. Pretty simple on the inside. Each phase comes in, has a connection that looks really strange where it brings them all together. It just doesn’t make s
Any sense, and Mike lets out a WTF? So he pulls out his meter. This is Turkey, they may have their own ideas how to do things. So he is checking each line. Checking from ground (the metal shelf the door made make a handy meter stand and ground. 440, 440, 440, 440, on each leg. Wtf? He re asses it, thinks about it. “Ah… they must be doing such and such to…” I stopped listening to him at that point. “Uh, Mike, you are really sweating. Its running down your hand onto that test lead. Maybe you should dry off…” at that point he got stuck. He stood there getting zapped and couldn’t let go. He was humming. I knew what was happening and body checked him to the floor.
Everyone was stunned. “Bob, wtf? Why you do that to Mike? He’s going to kick your ass now” dude was a Tae Kwon Do instructor. A very fit 275 pound man.
He gets up, flexes a bit like the hulk. And says, “Thanks Bob. We wont talk about this? Its our secret?” I said, “sure”
I saw him again almost ten years later in Korea. He didn’t recognize me. So I began to tell the story. As soon as I got the the part about 4 phase power coming in our office… He said, “BOB! Yeah! I remember you now! Dont tell that story. I’ve already heard it, and that story pisses me of.”
All the guys sitting around said, “yeah, he hates hearing stupid stories, especially once he heard them again. I’m banned from telling the Quasimodo joke around him.
Later, in the truck, that same guy started telling the joke when Mike was not around. Mike got in the truck a few minutes later and just gave him such a stink eye. When he finished we all laughed. Not so much at the Joke, but at Mikes face. And then the guy said, “W-W-When did you get here?”
Mike, “Dont you worry about that. You’ll be target dummy for a little bit. I need some practice”
It’s difficult finding the right clips to make one, who sells this drop cord?
Please tell us with details what did ther last time
I personally had one of my customers reset the circuit breaker while on the job in another part of the house Shocking!
I’m doing a outlet in my well house to run a heat lamp and this is what I have done . Of course I turned off the power but in a situation where you are at a customer house this is sometimes the best option if you are safety conscious person .
i NOTICE MOST AIR CONDITIONERS WALL TYPE ARE USING 115 VOLT POWER IN STEAD OF 220 VOLTS , MY OLD AIR CONDITIONER IS 220 SHOULD i REPLACE IT WITH A NEW 115 VOLT UNIT AND REWIRE MY 220 VOLT OUTLET IN MY HOME
Very simple job
when the AC co/ electrical co last year installed a new ac unit at my home they wired in also 110 plug ground fault for use in the disconnect panel box by the ac unit. I have used it when working on my home, saves a long extension cord to a 110 plug
That's rare but, as an HVAC tech it is surely appreciated when I run into it.
I had a building superintendent hook up a 220V oven to (2) 110v lines, the customer complained it wasn't cooking just getting warm, When I checked the building didn't even have 220v going into the apartments.
I was hoping this would show how to take a double circuit breaker (220V, 40 Amp) and split it into TWO circuits 110V, 20 Amp each. Please post instructions or a video on that? Thank you
I know this is 2 years old but I think you'd hook up the first outlet like this then daisy chain the second outlet and you'd have 2-110 outlets but they'd be 40 amp solely or combined. They do sell 20 amp 2 pole breakers, which would be advisable.
Finally electrician that knows what he’s doing!
Can it be done with two wires
Hi good videos i have a question, I have a power inverter but is 230v one L one N and one Ground can i converter to 110v just as you did in this video? Thanks
Tengo un aparato de 220 y mi luz es de 110 que hacer
What you’ve done is temporary. Can I add a 110 outlet next to my AC breaker box drawing the 110 from the 220 and still have my AC working?
Same thing I'm wondering. In theory yes, probably not up to code though.
@@tonio909 Not an electrician, so take this with a grain of salt, but no--I don't think you can USE 110 from that same circuit while simultaneously using power at 220. I believe that the two hots in a 220 circuit are carefully 'in phase' (maybe 'out of phase' is a better term?) with eachother, which is why a neutral is not needed. If you use one of the hots, and a corresponding neutral, then you'd make the two hots unequal/phase shifted/something along those lines. Plus, its very likely you wouldn't have a neutral wire anyway, and using the ground as a neutral is definitely not wise. (note -- all this is speculation!)
It could work if you use just one hot line from the 220 circuit and use the ground as your neutral. Granted you would have to use a GFCI recepticle since it would be an ungrounded line, secondly I would not do this myself and it's certainly not up to code. I am not an electrician, one should have a fundamental understanding of the basics and understand how to use a Multimeter before attempting this.
An a/c unit doesn't require a neutral wire a receptacle does , there is no neutral the box he's showing, an there a good chance that your box doesn't have one either
@@gregberban9273 no neutral, he used ground wire instead
I have a query!!.... If the stepdown transformer is a 1000W and the equipment which I'm using is 50W; will the power consumption be a 1000W by the transformer or just the 50W by the equipment? I dont want to pay an air conditioner's worth electricity bill for a small lamp!
Please help! :(
Maddy :x just 50w +-
You will consume 50 Watts plus maybe 10% ...= 55 Watts.. The transformer is stated it's maximum is 1000 Watts
A way to do this while leaving both of the 240 hots connected? We saw a well, where somehow they were pulling 120VAC off of the two fuse box. The well pump is 240, and the sump plugs into an 110 VAC outlet that somehow steals it's 110VAC from inside the two breaker 240 VAC box.
source wiring is 4 conductor [hot/hot/neutr/grnd]
How in the world are they getting the 110 VAC outlet pullet off of this two fuse box??
Simple in the US- Hot L1 to Hot L2 is 240v, L to N is 120v. In most situations outside of a main breaker Ground is bonded to N. So you just use EITHER L! or L2 as power (black) and hook your white and green to N (or ground). But remember the breaker will only handle a certain amount. If you draw more than the fuse/breaker amp capacity with both devices running, you will trip/pop breaker/fuse.
As always remember, size your conductors properly as too many amps on too low conductor mass = Heat, which could lead to fire.
@@PhantomDragonX so he did connect both the neutral and ground on the disconnects ground bolt? Blk to 1 blk G&N to ground? That's what it looks like but I couldn't tell for sure
@@JoeNathan42420 yes. remember, the 3 conductors aren't anything special in and of themselves - just pathways for electricity. We use "grounding" as a measure of safety.
you could put one wire to hot, and one to ground and still get 120v power (in the context of this video) and leave the other completely out. Again though, saftey is important, don't let a short happen.
God bless thanks
Did he put the ground and neutral on the disconnects ground bolt?
Yep, perfectly acceptable for pulling temporary power, been doing it for years as an HVAC tech. HOWEVER, this would be totally unacceptable for any type of permanent indoor wiring.
SHOCKING!!! LOL i Love live wire... i Like, OLE!
Make 220 out of 110 , that would be a good video !!
It can be done
Convert the neutral of the 110 to a hot by removing it from neutral bus at the panel and adding a 2 pole breaker. That's gives you 2 hot 110s for ur 220 plug
Rubber gloves = priceless
I Would have dropped the meter too! 😂👍 Thanks!
That's how I get free power from mu neighbors house
😂😂😂😂
Did you just connect BLACK AND WHITEWIRE?
Black to 1 leg and white (neutral) and green (ground) to the ground block. This is perfectly acceptable for temporary outdoor use, as an HVAC tech I've been doing it for years, but it IS NOT safe for any kind of permanent indoor use.
he didn't say we shouldn't throw the breaker. your choice. i will throw the breaker until everything is tight and ready.
if you need to watch this THROW THE BREAKER!
Very good point. If you had to check how to do this, do a favor and throw that breaker.
Sadly that has been some peoples famous last words. "I'll do it hot."
Did you notice that his meter fell unexpectedly just before he proceeded to be UNSAFE! not sure I would hire him. you may be paying for his damaged equipment along with the repairs.
So please place a value on your life by doing it safely.
He just gave OSHA his telephone number...! lol
0:52 rip volt meter
I knew there would be this comment right when I saw it happen!
Brilliant, Doing a demo and saying, "Don't do it this way ... but I'm going to." This is stupid because you know someone is going to do this without turning the power off and get hurt.
No it's stupid if they don't take his advise..... It's not on him, it's on whoever takes the chances of doing it if they get zapped. It's called personal responsibility, people should start taking some instead always blaming others for their own stupidity.
and this was the last video he was seen alive
Hell yeah you tube is getting better by the day, R.I.P. silly guy..
I liked
Did he just say "borrow power from the neighbors house?"
Wow
Safety out the window with this guy. Haaaa
Ground and neutral go on the same connection?
Randy Miller yes they do in that instance as there is no neutral wire landed in that panel as it is 240 volt but the reason being that ground and neutral work together like that is that in the main breaker service panel ground and neutral are bonded together
But doesn't that make the grounds in the house HOT now?
@@GrandDudeBill No, there is no positive power running in the white or ground.
@@GrandDudeBill It depends what you mean by 'hot.' There WILL be current, yes. But potential to ground will remain 0 if continuity to the transformer remains.
I got shocked and died doing this, be careful folks
Holy shit. Your ghost posted this comment. RIP Mr Schizer
Natures way of thinning the herd...........
This seems RIDICULOUSLY DANGEROUS!! Anyone who thinks they want to try this, please add my name to your will!!!
Who am I? You have 49,000 subscribers and almost 200,000 views on this. So, my hat is off to you. I would suggest this much: if you’re going to do the work I saw you just do, you might wanna wear a decent pair of gloves. Cannot hurt. And it might save your life.
I do have a question… at what point will your breaker trip if you over-amp your newly established 110V connection?
The breaker is not going to trip when hooking up a small a/c pump, especially considering it is probably not even pulling 10% of the rated load for the existing wire gauge or even breaker amperage. The purpose of this is only being temporary curcuit used for a very short duration. You are aware that they sell that adapter "whip" he is using commercially, right? These have been used for a long time in various professions.
He needs a new box and a new multimeter.
No gloves, water in the device. Hot leads? not a good idea. :)
What?? I drop my multimeter all the time, either at work or home and it's yet to hurt me😅🤣😂

for many years, as required by the n.e.c.(national electric code ) to have a 120 volt receptacle within 25 ft. of the condenser. this law was to prevent electrocution by doing stupid hacks like you just seen. it has happened on several occasions.
It may be code, but I rarely see it. Sure would be nice though.
Hmmmmm. He is working, taking high risk of injury, violating numerous OSHA safety rules, showing it on TH-cam, and giving out his phone number. What a country we live in!
What OSHA safety rules would those be? You have no idea what you are talking about and only came to make a negative comment. There is nothing wrong with doing this as a temporary source of power and while monitoring the operating unit. If you dont know what you are talking about then keep your comments to yourself, some other idiot that doesnt know either might just believe you. There are commercially available jumper boxes made for this specific purpose as well as to go the opposite direction and create 220/240 from two 110/120v outlets. 🍻
hunt2eat Ok,obviously from your comment, you think I am full of it. To help you understand, because you obviously do not use electrical safe practices, I will explain it to you.
1. NFPA 70E (National Fire Protective Agency book 70 E) is the safety book for electrical workers. In some cases, these mechanical people are required to have electrical contractor licenses. NFPA 70E says that you must wear proper PPE when testing voltages( obviously no sleeves and probably not a all Cotton shirt), no gloves. All required in case of explosion. He went further than testing though. He stated "do not do this" because he knows it is wrong, yet did it on camera and is being seen by many on TH-cam.
As you can see, these are NFPA 70E violations, not OSHA as I said. Fact, OSHA is called out when there is an accident. They look for violations of their rules. One of their rules is to follow NFPA 70E. So since that was not followed, then they can write numerous situations for the person that did the act, and also the company that employs that person in this video.
BTW, as an electrical engineer designing electrical systems for buildings since 1983, I believe that I do have some knowledge of safety. I only point things like this out because, someone will do what he did and get shocked, burned, or worse die because of it!
Always be safe, the life you save may just be your own!
Respectfully, Kevin
I don't care for the idea of temporarily removing a wire from an electrical box to draw power from. You could slowly strip the screws over time. Just don't be lazy and use an extension cord, or use a battery powered pump. The NEC is pretty clear that there is to be no current on the ground conductor. It's bad practice.
Temporarily it is a non issue, but something like this should NEVER be used in any type of permanent wiring. As to the extension cord, apparently you've never done any work on rooftop HVAC equipment. It could take 500' of extension cord to power a vacuum or recovery pump, and that would create its own set of safety issues.
This is a video of what not to do..⚰️⚠️
Too much work inside that box, do it inside the Condenser. Easier it is!
I like how this guy he's trying to be professional at all and his meter fell and smashed on the ground and he's pretending not to notice and then he goes on to tell people not to do the work themselves cuz it's too scary look what you just did I'm fucking laugh and my guts out
110 and 230 volts are obsolete now and have been for decades. The nominal voltage norm now is 120/240 volts.
Same thing
@@undercoveroverwater8413 these old men around here always talking about “is it 110 or does it got 220?” 🤣 but it’s the same exact thing and I always know what they are talking about.
I know you are trying to save time but you could at least wear gloves
He died the next week
For the sake of your clients homeowners liability insurance and for your own safety you should consider a portable 110v portable generator..Especially as you show on your video that you dropped your voltage reader and breakerbox cover..Please be careful Pal.
LOL I disagree but like the comment. OLE!
I've done tis many times.
If he knew electrical theory he wouldn't do this. He could easily burn something up in the house. You never use a equipment ground conductor has a current carrying conductor. It's the pathway for a gri
It's a pathway for a ground fault.
Look at your lug panel, all your neutral wires are tied to ground in the box. At your breaker box ground and neutral are the same thing electrically speaking.
Dangerous.
So you are suggesting that someone should use the grounding conductor as a current-carrying conductor and that they are going to plug your 15 amp(or less)recovery rig into that 30 amp condenser circuit?!? back in my early days in the trade we used to refer to this as a widowmaker rig and it's just a really bad idea to suggest that someone try this...and if someone has access to the load center to shut the breaker off like you suggest they do,I would think they would certainly be able to locate a proper receptacle to plug an extension cord into and plug their portable GFI adapter into that cord.
whoops, I think I may have posted my reply to the wrong place, I meant to post it to the main reply area, I'm kind of new to the TH-cam reply thing. I work with tools and hands so the whole TH-cam / social-media thing still kind of befuddles me
aside from a biker doing 180+ mph, this is the most suicidal video i have ever seen.
You've never seen a lineman go into a 4000amp panel while its hot then. 120v isn't really that "suicidal" if you know what you're doing. He did it in a safe manner and atleast capped the hot until he was ready.
why, I've done this many times where there was no 110V, only temporary, definitely not a permanent rig, be careful of exosed wires!
120 only tickles a bit
Better solution. Don't be a cheap ass and drop $200 on a generator.
