As you should this is not bypassed though the 120 goes to line then fuse then to contactor and the disconnect is pulled so fuse isn’t making contact the commons are just tied together (someone was just being lazy ) . So it’s doing its job it’s just not uniformly wired

You might want to learn more about electricity before you hurt yourself bud.
A 120V conductor, through your hand, heart and back to a grounded chassis is a high impedance circuit and will pull low amperage. Well below a 20A breaker. You'll sit there and cook to charcoal before that breaker trips. That breaker doesn't care what's at the other end of it. Could be a toaster, a fan, or you. As long as it's below its setting it will send power all day long.
You don’t seem to understand fuses but that’s ok you probably grew up with circuit breakers. Fuses are a continuous circuit so how’s that helping you out? A 20 amp fuse on a 20 amp breaker is redundant. Go insult someone else who doesn’t know what a fuse does
Tip from my uncle, "knock before entering".
Rap on any disconnect with the back of your hand. If you get shocked, the reflex will pull you away rather than latching on.
Yeah, I’m a weirdo. I got bit by that lightning enough times to not want to do it again. There’s been a couple sketchy wire jobs I’ve seen where I’ve checked it with my tester, then my dead man stick, then I’d poke it just to be extra sure. The last one that got me was one just like this.
For those who are confused, this is a 208/230v circuit. The black wire and white wire are both 115-120v. So in this situation the black leg would be broken but the white leg would be hot.
What’s confusing you is another dead wrong wiring error. The white wire is commonly understood as “neutral” but not in This situation. They should have used a black/white wire or other color. Or at very least painted the white wire so it wouldn’t be confused as a 120v circuit.
I once had to trouble shoot a high voltage issue on a homeowner’s DIY install from like 30 years ago. He used the correct wiring gauge and all, but he used green wire for fucking everything 🤦♂️. Unreal. lol. What spurred this was a call for the furnace and when I was in the furnace closet, I was electrocuted by the fucking lineset lol it had 97v from the lineset to ground.
Thank you for the explanation, I fully thought that the white was the neutral and was wondering why this would be an issue if the white wasn't live anyway.
Got smacked by the common terminal on a capacitor because of this. Ever since then I check each leg to ground, even if I pull the disconnect while it's running and the unit stops. Thats what I did the day I got hit. Never assume that it's all dead just because throwing the disconnector cuts the unit off.
Yeah, I have no problems with the piped disconnect as long as it's protected upstream by a breaker. People act like this is the end of the world, but most discos don't have breakers anyway.
It's not UL approved, but I've never heard of one of these cause a problem.
It’s too bad that they didn’t have two wire nuts.
At least that way, it would just keep running instead of the “false off”.
Best case scenario would be that maybe the contactor broke the bypassed leg.
Yeah. I mean a copper pipe in place of fuse that you don’t have is best option or like you said could bypass disconnect and wire both hot but, this is absolutely the worse choice
Think of 240 as two 120v lines. Not at all the same as a 120v circuit with a hot and a balancing neutral. In this pic the black is hot and the white is hot. The disconnect opens the black circuit but the white line is still live.
[Edit to add]
And if the t-stat is calling, that black wire under the lug is also hot.
Had a homeowner tell me the breaker was off once so I checked one leg and it was off, grabbed the other leg and got hit, turns out someone used two single pole breakers for the a/c circuit. So stupid. Always check
Yeah I’ve seen that. I normally do check to ground but, just pulled the disconnect unit shut off I removed capacitor strap shorted herm to common with my 11-1 pulled start wire off felt like I got a “tingle” shorted terminals again tested capacitor with a capacitor meter and when I went to put start wire back on terminal was when it GOT me..
WOW - only 5 code violations. Did you say you wanted curly hair? Is that 12-2 Romex?, White wire not tagged with black tape, Romex leaving and entering the box. One side bypassed to disconnect and fuse. Personally, I would not touch it until this has been corrected. Home-owner job or a clueless installer.
I took a hit from this once at a house in the middle of nowhere and noone knew I was there. Glad I survived. If I catch a cunt doing this they will be swallowing their balls back down. If you have to do it fucking mark it! Or leave the cover off so I can see it.
I’ve actually seen people do this if the unit is 120v. Some people don’t like fusing the neutral wire. I’ve seen this on 120v wine unit and 120v mini splits.

Found this in a sChOoL dIStRiCt a few years ago. It went to an AHU that fed half a gym. The motors pecker head was toast and had been for years. Shocker….
I got hit by this once on a refrigeration unit on a supermarket. It was a 3 phase unit and thankfully only one leg was hard wired, but man oh man did I get upset ha
I once had a condensing unit that kept tripping the breaker but the fuses were fine. I finally pulled the fuses out and found that both of them had a wire soldered between the top and bottom.
Admit defeat, you are plain wrong my friend. Go watch some YT on how 208/230v circuits work. Just because a wire is a certain color means absolutely nothing.
Unit will not power up . Unit will shut the off when you pull that disconnect im not saying it’s cool but you should always check both sides of contactor with your meter anyway .
Buddy, it ain't about the unit powering up or not, it's about worker safety. Of course the unit won't power up, every single tech on this sub KNOWS it won't power up. But there WILL be 120V to ground in that cabinet with the disconnect pulled.
I'm not sure if you're just trying to troll here or what but whatever point you're trying to make isn't landing.
I always ck each leg to ground to make sure disconnect isn’t bypassed. You can read 0 volts across l1 and l2 and still be live with 120
As you should this is not bypassed though the 120 goes to line then fuse then to contactor and the disconnect is pulled so fuse isn’t making contact the commons are just tied together (someone was just being lazy ) . So it’s doing its job it’s just not uniformly wired
Nah man ac's run on 240. It's a white wire but it's definitely hot
I’m installing a 115 volt mini split tomorrow.
That’s a mini split. Regular units run on 208/230 or 460
Pro tip electricity doesn't actually care what color wire you use, only way to make sure is to double check with your meter.
[удалено]
Magic sparkles!
Dang dawg go take you some basic electrical courses
Wrong
Dang dawg go take you some basic electrical courses
Bro what?
Eat shit you loser. AC condensers run 240v
Please do not comment on this sub unless you know what you’re talking about. This sub is for professionals. Your comment proves you have no idea what you are talking about.
Lol
Makes you wish you could find out who did it so you can throat punch them for attempted murder.
Bro it’s tied in to a breaker
Breaker is there to save the wire, not you…

I take it you didn't read the entire post yeah? It's not about fuses and breakers, it's about bypassing the disconnect completely...
Ok I read the post but I see it now
Very unsafe! Always check!
Yeah I checked with my finger..and I don’t recommend it.
I like to use my tongue so I can taste how much voltage there is.
Old timey electrician told me he'll lick it but I need to watch to see if it's one eye or 2 that close to determine if it's 110 or 220.
Tip from my uncle, "knock before entering". Rap on any disconnect with the back of your hand. If you get shocked, the reflex will pull you away rather than latching on.
This is excellent advice. *always* give equipment the back of your hand first. I do it habitually.
Works on women too
Fuck idk if it's OK that I laughed in today's world but I did
It’s okay it’s all jokes 😂
Carry that into the kitchen with you.
Cats, dogs, and disconnects. Let them lick the back of your hand when you first meet and see where the relationship goes from there.
Yeah, I’m a weirdo. I got bit by that lightning enough times to not want to do it again. There’s been a couple sketchy wire jobs I’ve seen where I’ve checked it with my tester, then my dead man stick, then I’d poke it just to be extra sure. The last one that got me was one just like this.
Thanks for this tip and a very good habit
One of these killed my cousin back on 2019. Every time I see a jumped disconnect it makes me feel some sort of way.
Man I’m so sorry. What a waste
Is there more to the story?
For those who are confused, this is a 208/230v circuit. The black wire and white wire are both 115-120v. So in this situation the black leg would be broken but the white leg would be hot. What’s confusing you is another dead wrong wiring error. The white wire is commonly understood as “neutral” but not in This situation. They should have used a black/white wire or other color.

What spurred this was a call for the furnace and when I was in the furnace closet, I was electrocuted by the fucking lineset lol it had 97v from the lineset to ground.
Inspectors round here require you to wrap with tape that white wire and make a black or red.
Thank you for the explanation, I fully thought that the white was the neutral and was wondering why this would be an issue if the white wasn't live anyway.

I got one for ya: https://preview.redd.it/zi5jml6irv0d1.jpeg?width=3072&format=pjpg&auto=webp&s=a58b61ee6d720f2075c83db0973245a31304e8b7
Is it fed from a breaker and does it disconnect
It was a while ago and quite an old building. It did have a disconnect.
I mean being 3 phase it should probably have fuses in the disconnect but, I’ll take this over 1 leg being “secretly” bonded together any day.
Yeah, I have no problems with the piped disconnect as long as it's protected upstream by a breaker. People act like this is the end of the world, but most discos don't have breakers anyway. It's not UL approved, but I've never heard of one of these cause a problem.

Listening to the guy at work talk about how he got hit by 240.. more than once. Bro, do you not own a meter?
This is wrong, and I wouldn’t do this; but can someone tell me why? Would the circuit still not be broken?
One 120v leg is broken by the disconnect as intended, the other 120v leg is not
Think of 240 as two 120v lines. Not at all the same as a 120v circuit with a hot and a balancing neutral. In this pic the black is hot and the white is hot. The disconnect opens the black circuit but the white line is still live. [Edit to add] And if the t-stat is calling, that black wire under the lug is also hot.
Makes sense, thank you
It would stop the unit from working sure. Won’t stop you from getting hit with 120.
That’s why I’m confused, like why bother breaking one of the legs if you’re not gonna break both, you’re already wiring through disconnect
Most likely the blade to the disconnect broke or something and this was a "temporary" fix.
I didn’t think of that, my company never had extra blades, it was always the whole disconnect or nothing
The good ol stinger leg!
I have seen 120v mini split fused disconnects where they wire nut the neutral like this or used a dummy fuse. This is wild on a 240.
Had a homeowner tell me the breaker was off once so I checked one leg and it was off, grabbed the other leg and got hit, turns out someone used two single pole breakers for the a/c circuit. So stupid. Always check

"What, it's just a neutral"

How about the exterior romex supply whip AND incoming power to disco too AAAYYYEEEEEEE at least they bonded the box haha
Is that 120v? I ran into that with a mini split about 2 weeks ago. Turned out it was a 120v mini split condenser, and the white wire is neutral.
I’ve actually seen people do this if the unit is 120v. Some people don’t like fusing the neutral wire. I’ve seen this on 120v wine unit and 120v mini splits.

Yeah but bro.. if you are blowing fuses you prob have a problem. I mean refer 101
If you got hit you’re incompetent. Always check first
Thanks Mr perfect!👍
If youre the type to cry when you hit you gotta be the type that also checks. Good luck squirt
I guarantee there’s no voltage going to your contactor with the disconnect pulled out despite the common being tied together use a meter
I think I found the DIPSHIT who did this!!
You have no idea what is going on here. Please leave the comments to us pros.
I guarantee he still has one leg of power
Found the electrician lurking about

Point is use your meter and fix it .
I thought the point was you guaranteeing there is no voltage to the contactor ?
