I’ll just add that I know I should’ve checked for power. That’s part of the reason I decided to post the video. To show what can go wrong if you don’t.
Thank you curtis 😊
My policy as an installer for best buy is trust, but verify. Never hurts to have a non contact voltage tester!
I've been zapped by 120 a few times and just two weeks ago I was zapped by 124 thanks to faulty string lights that claimed to be LED but were not actually LED. (dang you Amazon)
But my other saying is.. I don't play with electricity. I play with wires, dead wires.
We’ve all been zapped a few times. Sometimes you have to work on things hot to troubleshoot, but in cases like that one of yours there it’s always good to check. I’ve done the same thing several times and found out with a meter before I changed it out. People do strange things with wiring.
Omg i did the exact same thing just yesterday! Disconnected an old mini split and killed the circuit before taking off the isolator/disconnect, as i was pulling the power cables out of the box i got the same POP and 💩 myself realised that someone had mislabelled the breaker box…ALWAYS TEST AND TEST AGAIN!
I've got a pal that used to work in your neck of the woods at some BIG textile plants in SC. He was in charge of a lot of HIGH voltage stuff, 7200 volt 3-phase stuff like chillers and such. Now it's rock crusher stuff which is the same kind. He's always told me to trust NOTHING; always check it. When he gets out of his truck he always grabs his hard hat and meter, usually the meter first. And always recheck a circuit after lock out/tag out. Might be mislabeled. It has been done here. And no ground is CRAZY! Good job, Curtis. Riley might've bit you coming in with a curly perm.
I could smell the smoke from here! LMAO 🤣🤣Curtis Que Pasa Way!, Be careful way! Keep em coming and stay alive.
Que onda buey? Es que me faltaba mi chispa diaria.😊
It only takes 2 seconds to get your voltage meter out I really enjoy these videos. Please be safe.
WoW Curtis, that was a close shave, looks like you need to double check for power, I'm pleased your still safe n sound 👍 Au
Glad your ok Curtis
Grammar nazi: "Glad your ok Curtis" --> "Glad you're ok Curtis" Difference in meaning.
That thing flashed at the speed of light. As a DIY'er, I always check with my meter. Appreciate your videos.
It's funny I see you using Noalox only after just seeing a video about it yesterday about how we've all "been using it wrong". Apparently the instructions are on the bottle. To apply it to the wire, work it into the strands with a brush, then add it to the connecter and clean up excess after install
⚡️⚡️
Dang! That scared me, and I wasn't even there ⚡⚡⚡
😎👍
About 3 years ago I got a call from a realtor that was panicking because she had a showing in about an hour and one of the AC's wasn't cooling. I was only a few minutes away so I headed that way. By the time I got there it had started pouring down rain. Both units are on a poured slab next to the driveway. I grab my umbrella and tool bag and notice that one unit is obviously running and cooling. The other one had a very hot condenser motor so I figured a bad capacitor (Summer in Texas, It's almost always a capacitor). I'm standing in about an inch of water because of a downspout that dumps directly onto the slab. I open and pull the disconnect, then start removing the service panel on the AC. About the time I get the door off I hear the compressor try to start. I'm thinking how the hell can that happen with a pulled disconnect, so I pop the inner cover of the disconnect and find that both legs had been bypassed. The pull was in perfect condition. Why the hell would anyone do that!? Anyway, I killed the breaker in the garage, fixed the disconnect wiring and replaced the capacitor. Had the compressor not have groaned I might not be here at the keyboard. I always assmed a pull disconnect was 100% safe. WRONG!
Great story...i have been hit several times by assuming. It's like clearing a firearm. Never assume it's not loaded...better safe then sorry. What you described was the perfect storm...rush job, rain, bypassed disconnect⚡
Man glad you are here to tell your story. I electrocuted myself really bad as a young man. I flipped the breaker and the light went out. So it's safe right? Not always, now days I still check first on anything, if I don't have a meter, I throw the main.
That made my heart jump a little bit 😮
Hey Curtis, **Nothing** in that electrical box is aluminum, nothing. Nothing on that circuit breaker in aluminum. The contacts there are some metal plated in tin - it's fine for copper wire. The guy who installed the last disconnect box didn't install a ground wire - he should have installed one. For electricians replacing a disconnect box - they can replace the box but have to also fix the prior guy's mistakes, an electrician would absolutely have to install ground wires, he has no choice, he's responsible, he's the last one who touched it. BTW: that compound isn't required in this situation - there's no aluminum involved here.
And, I'm not going to mention the green bonding screw - it's complicated.
I agree with everything you Said needs a ground wire installed and is there a disconnect at the air handler unit ?? inside in my state per code in my area a disconnect is required to be within so many feet of the Air handler unit not outside just my thoughts not on the job so just my opinion
That drill bit is worrped 😎
I learn something new in nearly all your videos. Thanks so much!!
DAMNIIT .... you KNOW what ima say!..... esp the ones with Nitrile ... GLOVES!!
Shocking job bypassing that
Shocking experience, hate it when that happens
Curtis, You won a gold lucky star today.
Another good production
I'm glad you didn't light up like a Christmas tree. Thank God. Please be careful. I really like your channel. I would really miss seeing your adventures. 😊
I would recommend that you get a non- contact voltage tester, and always keep it in your pocket, Santronics makes some of the best I have used in my opinion, meters have their place,, but these things can test quickly/safely and maybe save your life...Bob
I never touch a wire without checking with one of these.
There is so much wrong here electrically I don’t even know where to begin. Please leave this work for electricians. After mangling the Eaton Cutler breaker did you really install a Square D breaker into an Eaton cutler hammer enclosure ? If anyone was looking for a video on how NOT to do this, this is it. Lock ring teeth do not go up, you don’t pour joint compound into a breaker (it’s not even needed here) You notice a missing bond from a panel and comment on it but don’t fix it ? Sheesh
Did you seriously just check for power while kneeling on the ground with your finger?
Non contact circuit testers can save lives
😬😬 wow shocking video 👍👍👍
Your guardian angel was looking out for you that day for sure. Mine must always be on a smoke break! 😂
I jumped!
YIKES! Im surprised you didn't get shocked when you were cutting the wires.
You are correct!there's not enough good contractors, Please don't kill yourself!
its always good to check your meter on a known live ckt also, had a bad lead once and got zapped pretty good in the old wiggy days.
Why did you reinstall the bulkhead fitting nuts upside down? The tits are meant to grip.
ferrules make it a whole lot easier to install stranded under set screws and lugs!
That was a close one! Especially with all the handling/cutting you did of that connection before that!
That's why you should never underestimate the value of a kneely pad and a good pair of shoes. If his knees had been in the grass, he'd have found out much sooner, and in a much less pleasant way.
He was lucky enough that he didn't touch both at any point till the scare.
Just this Tuesday, I was doing a tune-up and when i go to check the condenser, i shut the breaker off turning the compressor and the fan off. Next im pulling the connections off the cap and BOOM goes the cap. Pull the cover off from the disconnect and sure enough it was bypassed. Just never know whats going to happen on these calls.
Curtis, you should have run a ground wire, or defer to an electrician. Since you were the last person to work on it, it is a liability.
Thanks for showing Curtis. Most utubers wouldnt have lol.
Always check wires with a voltage tester before you start jacking with wires😁
After people called you out for not using the oxidation inhibitor I guess it's OK to do the same for leaving so much copper exposed under the breaker, and also for not putting a crimp on ferrule on those wires. Clamping on to stranded wire is really not a good idea because those strands will shift over time leaving a loose connection which will start arcing.
I am glad Curtis survived that learning moment. Back in the day the ground was provided by the armor of the flex conduit until it is removed. So todays wisdom is to have a ground conductor. I would think that replacing the disconnect would require an upgrade to current electrical code standards. It would be prudent of at least upgrade to a GFCI breaker. By the way Curtis there is a wire strip gauge molded on the side of the breaker, please use it. Glad you are still with us brother!
Are you sure those set screws and lugs are aluminum? I don’t think so. Try tin plated steel.
You are correct
Still lube them with the dielectric grease or noalox or whatever I have with me at the time. Makes it so much easier getting everything loose down the road. Might be 20 years from now when we’re an old man. The communist Chinese plastic guts like to break out of them.
@@USA-GreedyMenOfNoIntegrity Dielectric grease or Noalox is at the opposite ends of the spectrum.
Dielectric Grease is NOT conductive. Noalox IS conductive. Put DIElectric Grease on After the connection is made to keep moisture out.
If you ain't testing, your guessing. Who that sound like!
That's Mikey pipes in New York City 🤫👍🤟🔥🏨
I'd take a Sharpie and label the breaker panel and the disconnect. May save someone's life or keep them from having a really bad day.
Always check power even after turning off the breaker for this reason, but a bad breaker can bleed through. I've been shocked a few times after turning off the breaker. Invest in a wiggy
You left me guessing, I always see you that you double check but you didn’t this time. I’m glad you didn’t get hurt.
The grease is for aluminum wire. Since there was no ground in place, I’d have a tough time walking away from this being the last person to touch it. I fear this is a nightmare waiting to happen my friend. A couple things - watch wire strip length on breakers and they really need gfci if no ground exists.
Stay safe.
I have an older home with no ground wires. Everything at the source is AFCI/GFCI protected. Dual function breakers are less expensive than I thought they would be.
The grease is a great tip, but I was always under the impression that if I touch any work like this it must be brought up to code, which means you must install a ground wire from the panel to the disconnect and to the air handler from the disconnect. This is why it's hard to gauge a job until you open the can. Great video
@@davidskaggs9914yep you are right needs a ground wire and by code in my area the disconnect needs to be inside so many feet from the Air handler unit not outside and label everything correctly not on the job just my thoughts.
The wire should be under the metal shoe, not the screw i think
that scareed me 😂
If you are feeling charitable, you might get a labelmaker and weatherproof labels (more visible and permanent than a Sharpie) to label boxes and breakers like that. Just a thought...
I always remove my knockouts before mounting the box. Especially if I'm using tapcons. Great job though.
You all got on Curtis for not using, and then you all get on him for using it. Let Curtis do his job
Lesson learned on this one. Fortunately it turned out well.
You usually test for live wires but not this time?
Nice work as always. My only concern would be that someone else possibly making the same mistake and turning that disconnect off thinking it is for the condenser unit and not checking.
Totally agree
I keep a label maker on my van for just such situations. Let the next guy know @@HVACGUY
poquita azucar y un padre nuestro.en este oficio no podemos hacer errores,que bueno que estas bien.
Fine job Curtis though before you get attacked by the trolls you are using the noalux incorrectly. Your supposed to use a brush and work it into the wire making sure that every strand has been coated otherwise it supposedly as bad if not worse than not using it. Though im 99% that noone has ever used it correctly and I use it the same way but i did catch something about it a few weeks ago so im sure that the trolls will soon be hearing about it as well and you know doing the troll thang
Thanks.
So this just happened to me this weekend. Intentional bypass of sorts. No power to tstat figured float switch. Condensate dry as a bone. LV fuse all good. No 240v coming in. Breaker not tripped. Remove panel cover 240v coming out of breaker. Animal ate my wires in attic but didn't short them? lol I was stumped. Swapped wires to other air handler breaker still no voltage. I was going nuts at this point. Remembered sadly on the way to Lowes for a new breaker anyway I had load sheds for the generator on both A/H's. Sure enough the light was out on one of them. It has basically a circuit board and contactor. Contactor was pulled in. Had 240v on line side 0 on load side. I bypassed it and power was restored to A/H. Turns out it's normally closed. Open is pulled in the reverse of a typical A/C contactor. This really had me stumped for a couple hours. Luckily a manufacturing defect on the board and Generac covers it. Later found out I could have left wires on the contactor and just disconnected the board from it. Learn something new everyday. I'm a DIY guy not an HVAC guy btw. Know enough to be dangerous. :)
That's what multimeters are for 🤷♀️
💥2:10💥
SHOCKING
You ALWAYS check for power what happened? omg glad ur okay
I just wanted to add is that wiring up to code? Why would they wire it from air handlers isn’t it supposed to have two separate circuits and a disconnect is supposed to be for the out side unit?
2:10... Shocking I always wonder you guys don't use testers on electrical stuff.
Interesting that the metal box was grounded on the brick wall.
Yep that was a rookie mistake, always check the power
Weird they would put the disconnect for the air handler out side.
My guess it was used as a Splice box. and should have been labeled as such..
I’m glad you’re ok bud.
Nope, I draw the line at possibly smelling like fried bacon.
It is easier to put the breaker in and connect the wire
Damn Curtis. Buy and use a voltage pen. Your luck is going to run out eventually. The screw that wouldn’t tighten, just put the end of a zip tie in the hole then put your screw in
Bypassing the fuses and using masking tape to shield the high voltage electrical wire connections. It is a disaster in the making. 🔥
Even if you think the breaker is off, you should check for current in the wires
Exactly. That’s why I decided to post it.
Can you a video on you Apple Watch how is holding on the field.
Leaving the disconnect ungrounded is very dangerous and you could be liable for being the one to install the switch in the event of an accident.
Yep that’s why the breaker didn’t trip from the ground short
Because there was no equipment ground conductor
@@johnheitz6583 It would not have Arc'd if that Cabinet was not Grounded..
The power to the Condenser may have the Ground present . He did not show that.
You can get Arc's & Sparks and not draw enough current to trip the Breaker.
That is why Arc Fault Breakers were designed, to detect Arcing .
If I hit dislike on your videos, it's because there's no captions! Since I watch on TH-cam for TV's mainly, that's the only way I can give you feedback! Even If I hit dislike on your videos I do still like them! I do apologize if that hurts your ratings overall! But like I said, it's the only when watching on TV that there's no captions since you can't comment on the TV!
I fail to see what was accomplished other than the customer charged for another disconnect outside within about 8-10 feet of the breaker box.
I don't see the purpose of the disconnect. That's probably why someone spliced the wires in the beginning.
Did you listen? He said that it was a disconnect going to the air handler in the attic. Maybe there was a package unit there before and they just extended the wiring to the air handler in the attic.
@@USA-GreedyMenOfNoIntegrity should have labeled it & added a ground
@@USA-GreedyMenOfNoIntegrity the disconnect should be in the attic then. They could have used the old disconnect as a junction box if a package unit was there previously. Not sure if that's legal. Kinda pointless to put a disconnect box when the breaker box was 8 feet away.
Ok I'm sorry but I had to laugh on the issues you had with the disconnect install. To see the things that didn't go perfectly made me realize that it does happen to others besides me.
Don't we electricians love the good old band aid (literally!) connections?
Need a slow motion of that.
did you shatter your watch screen halfway though this video?
Never hurts to have a little extra circuit protection. Glad to see you’re using an oxidation inhibitor you won’t regret it. Quality control on parts is a dying art these days it seems. Situations like this is where the NCV test function on your meter make’s verification the conductor is de energized quick.
aren't your supposed to wear the bell bottoms when you are doing the disco?
Always easier hit the knockouts before mounting the disconnect as well as marking your anchor holes and then drilling into the brick without the disconnect getting in the way.
YOU KNOW i got hit by 460 one time it was like some one hit me with a base ball bat it knock me 5 feet and it knocked me down on the ground i said thank you Jesus
Dang
Your very lucky anything over 240 has the ability to grab you and clench every muscle in your body.
Sorry, Curtis, but the exposed wires at the circuit breaker terminals are a 'fail.'
I noticed right off in the Video of the Seal Tight leaving the box and going up the Wall.
For someone that can feel 24v ac I was perplexed to see You "Finger" the end of the Wire ?
Get a Pocket voltage detector.
Glad you didn’t get hurt on that Curtis . Wouldn’t it have been better to make that a weather proof junction box and install a disconnect at the air handler? 👍🇨🇦
😊😊👍👍
This is like the second or third video I've seen you almost get electrocuted. I hope Lady Luck continues to be on your side, but maybe you should make a new habit of always checking if the circuit is live before operating on it.
Man you almost charged your battery real good. Why they ran it that way to start with beats me. In my area, if you splice wires, they have to be in a box. That had something to do with it I'm sure, but it doesn't hurt to have an extra breaker or disconnect. Looked nice when you were done. Man I like those anchor type screws, so much better than using those plastic mollies.
You do a lot of work in load centers and disconnect boxes. Personally I believe that should be handled by electricians as a power distribution issue and when the power enters the equipment you take it from there. Electrical really is another trade separate from HVAC and should be treated as such.
Leme guess, you are a union electrician...............
In North Carolina you have to be a licensed electrician to change a disconnect. You can't even disconnect the high voltage with HVAC license on change outs.
@@kevinwalker4623 Probably let a plumber fix your roof...
@@josephfarrow2685 Don't think that sealtite is up to code for a grounding conductor, no matter what state your in.
You are correct about that. I was just making the point that in N. C. That you have to be a licensed electrician to even touch high voltage. Then maybe it would be done correctly.
🤣🤣 I use the same hammer.
Glad you ok
Grab one of those pen tester and keep it on your bag
Proximity Tester. They're great for tracing back to a breaker. Tape it on a wire, let it make the warbling sound or flash it's light, while you turn breakers off. As soon as you kill the breaker, the warbling sound, flashing light or both stop.
You need a volt stick
Curtis, electricity is a no joke. You must respect it. That means you must always check for power. You must always make sure noone would be able accidentally turn it on while you're working on the system. You must always work with appropriate gloves. You must do all this if you want to live a long life. You were just lucky here, but don't accept this as granted my friend.
If that disconnect box had been grounded, you would’ve been electrocuted.
Why is there a disconnect even there? That's very misleading. Next person will probably think like you too. By the way, if you had gotten shocked while squeezing the pliers, you might not have been able to let go. HVAC technician was electrocuted to death a few years ago in a town near here..
There’s just no way I could replace that disconnect without a ground wire…you need to bring it up to current code, and now you are liable for any future injuries 🤷♂️ just sayin…also the nuts were installed upside down inside the box. You do you, but I would never film myself doing something like this…I’m a fan just looking out for you and your best interests
Yes, Curtis does great work on HVAC, but this was more a video on how not to do electrical work. It can be tough setting limits on correcting an improper installation, but without installing ground wires this improvement might have actually made things less safe. Before it was unsafe and looked unsafe. Now it is unsafe but looks safer. Not an improvement.
You are leaving a shock hazard by not adding a ground wire. Some kid could be killed if the motor windings short to ground.
The condenser may have a ground. He did not show that...
@@m9ovich785 the circuit he worked on should be grounded including that local disconnect. This basic electrical 101.
@@larrynash7940 Most certainly.
But the disconnect He replaced was not for the outside unit. The arcing to the Cabinet showed that the Cabinet was in fact Grounded via another underground route.
There were no grounding conductors. Arcing took place because the neutral wire and hot lead shorted on the box.
@@larrynash7940 Thats 240VAC NO Neutral.....
Ya you should not have even touched tht disconnect without a ground present tht needed a rewire why I don't like it when you hvac guys act as sparks😢
Exactly & load wires stripped to far
@davewolfy.5932 lol his 1st attempt without twisting the strands tight together was priceless I myself use ferrules ( got that from the UK sparks along with wagos ) the only thing he did right as a spark was not cleaning the brick we sparks never clean anything lol. 😉
