having trouble with electrical, outlet has enough charge to shock when i touch it but not enough to power a light bulb, I tried the light bulb in other sockets and it is fine. it is a gfci outlet at the end of the run. i get shocked but there is not enough umph to light a light bulb. can someone go over basic sparky trouble shooting techniques with me.
>breaker off follow the line.line goes behind some tile and is in the crawl space in the attic.>are there any nicks in the line possible at wire harness, house is wood construction will check rubbing against light housing possible damage there>is the whole circuit dead or just an outlettwo outlets are dead on separate circuits one install as part f a remodel one part of the original construction, mixing aluminum and copper wiring>did you wire two circuits together on the same bardoubt, i would be incredible lucky to not have blown my face off with 240 had it been different bars.>is the line long enough to create a small capacitor and that charge is just elevation changethis is not a skyscraper, this is residential with the line running less than 100ft>have you found all the outlets that are deadi will start looking
>>2974593>two outlets are dead on separate circuitstwo outlets on same circuit, remodel sparky reused old aluminum line.
>>2974591replace the outlet, or at least bypass it by nigger rigging a jumper from the light bulb directly to the wires in the wall. if the bulb still won't light up then the wires in the wall have a high resistance somewhere, which you'll have to trace upstream.
>>2974591Bad neutral connection. Hot is OK because you still get shocked (not a really good diagnostic). But no return path to light a bulb.
>>2974591pic related is the sign of a 3rd world coun...>aluminium wire...i mean 4th world country.
>>2974662
>>2974591Buy a multimeter you poorfag.1. Test ground continuity.Run an extension cord from a known good outlet and make sure that a) there is no voltage between the two grounds, and b) there is continuity (low resistance) between the two grounds2. Test live wireMeasure voltage between the live wire and ground:Make sure live wire has the appropriate voltage for your country when there is no load.Make sure live wire still has the same voltage when the light bulb is connected.3. Test neutral wireMeasure voltage between the neutral wire and the ground:Make sure neutral wire has close to zero volts, when there is no load.Make sure neutral wire still has close to zero volts when the light bulb is connected.4. Test live and neutral wireMeasure voltage between the live and the neutral wire and make sure it's the same voltage you got between the live and the ground wire.
resolved, circuit was controlled by main breaker box i thought it was hooked to the sub panel, breaker tripped during demo and nobody noticed. I can not explain the weird shock, but i am going to assume it is not a problem.
>>2975261> I can not explain the weird shock, but i am going to assume it is not a problem.Might have been some asshat wiring live from two different breakers to your circuit. Encountered that when I bought my house.>turn off circuit I want to work on>measure circuit: still live>wft.jpg>open junction box in hall>two live wires hooked up to two different breakers connected to my circuit's live wire.Sometimes, people who worked on your electrical wiring before you were drunk, high, tired or distracted. Act accordingly and measure early, measure late, measure often. It definitely bears investigating further because you probably want your circuits to be off instead of still live when you flip the breaker.
>>2975024the deranged cope of the 4th worlder
>>2975446>cope
>>2975476cope of the goyest of all goys, yeah>aluminium wires and wirenuts in his cardboard shed of a housegtfo you clowns, lmao
>>2974591Everytime I start thinking tradies are gate keeping cunts,>outlet has enough charge to shock when i touch itI'm reminded why we need gates.
>>2974591bro those wire caps go bad with time you are suppose to replace all of them every 5 years
>>2974591>>2975024Just use Wagos.
>>2974591Why do people use these? How do you know that the resistance is perfect across all strands of wire when twisted?
>>2976217I'll put my penis into your wago.
>>2976218Because that is not needed. It makes good enough contact with the wire to transfer its rated current without overheating. That is all you need. It doesn't need to be perfect. That said, wire nuts are cheaper and just as fast to use if you know what you are doing.
>>2976218>How do you know that the resistance is perfectIs you're house a big microchip or something?Resistance in home wiring just needs to be good enough. Theres acceptable tolerance for resistance and even voltage.
>>2974642>Bad neutral connection.This
>>2976450a housefire wrote this bullshit
>>2976450You know because a proper wire nut connection is twisted together before putting the nut on. The wire nut itself just provides a protective cover and some extra insurance that some gorilla doesn't tug the wires apart in the future.
>>2977689>proper wire nut connection is twisted together before putting the nut onthats bullshit
>>2974642> Bad neutral connection.This.Neutral is tied to earth, and you're weakly tied to earth by capacitative coupling. This is why those testers (the ones which you poke into the live hole and touch the top) work.But without an actual neutral connection, the current is in milliamps, maybe even microamps.
>>2977692You dont do this for a living do you
>>2975304I get the feel turning off breakers is a memeI reworked almost all my house wiring myself, and got zapped dozens of times. It's just a tingly feelSure I get being careful especially when you are in a narrow space and wear rubber shoes, but it's not industrial voltageMaybe it's cause I'm in europe and we got lower amperage?
>>2977692This guy thinks back stabbing an outlet is acceptable.
>>2977721I just dont enjoy getting zapped, It hurts. And one time on a job i opened a neutral bundle with the power on and a light in the stairwell that was on caught fire and the one at the top of the stairs burnt out. Backfeeding can be too intense sometimes
>>2976217if you want to actually do it correctly, use paste for al wire to supress galvanic corrosion
>>2975481Israel will face judgment for its worship of Moloch.
> light flickering> open upam i going to die if i rewire this to disconnect from the ground terminal and only have hot and neutral?
>>2979125
>>2974662Nobody in the third world uses this. Electricians here are too poor for that. They just wrap them in electrical tape and call it a day.
>>2979125Probably not. I'd say chance of live line somehow hitting the metal chassis while not also blowing the circuit breaker is smaller than a rupture of PEN that is <10mm2 Cu. Do you not have PE avaliable to do this correctly as TN-S?
>>2974662thin Al wires are common in eastern europe in old installations. We actually used to do Cu 100 years ago but then commies declared that copper is too strategic and valuable resource to waste it on household installations.
>>2979125>>2979138I know they do things differently for 240 volt systems, but why exactly is the ground tied to the neutral using a Wago? Also, why is the insulation stripped off of the blue wire and it connected to that screw? Is this some kind of ghetto ground setup? Its like you guys imported Floridaman and he became an electrician.
>>2979138Dont connect it to the ground at all. Remove the 3port wago.Just hot and neutral.You dont need ground on there because novody will touch the metal part anyway, but this is wrong
>>2979161> Do you not have PE avaliableThere's no third conductor / PE at any of the junction boxes or breaker boxes I have access to (Two locked breaker boxes, meter box has wiring hidden behind a tamper sealed panel).>>2979173> Just hot and neutral.The problem is there's continuity between the ground terminal and the lampshade holding metal legs. It is 100% getting touched during a bulb change. I left the ground neutral bond in place to give a chance for a ground fault to clear.
>>2979308You probably have a panel rfi anyway so you actually made it worse. Now the case is always slightly electrified and if you do touch, it will not trip unless you.manage to sink all 10 amps of your breaker. If you had left it floating, even if there was a ground fault, it wpuld just sit there until you touched it and current tried to move without going back through neutral and the rfi would trip
>>2979308That screw you are touching on the light fixture? That is the ground screw. Of course it is going to have continuity to the metal of the light fixture. THAT IS HOW THAT WORKS. What is the point of having a ground if there isn't continuity to all the metal bits you might touch?The question is, without having your fucking hot or neutral bonded to anything fucking stupid, do you get continuity between them and the ground? If the answer is no, LEAVE IT. It is not ideal but it is better than whatever shitshow you are current using. If the answer is yes, you need to find out why and fix it. Not start tying shit to the neutral like a fucking retard.The ideal solution is to run an actual ground line to the fixture be we know damn well you aren't going to be that competent at fixing this.
>>2979330>>2979349I swear to god I'm onto something though.The UK runs 2 wires with a disconnected ground, because the circuits are backed by a GFCI or other meme residual current device.https://www.youtube.com/shorts/vmPdiqGjFcoI have normal fuses, the bonded neutral is marginally safer than leaving the ground disconnected. Until i set up GFCI.
>>2979457You are so fucking retarded you are blowing smoke up your own ass. If you tie the neutral to the ground at the device then the device is now live. It isn't safer. It is much, much worse. No ground is only a problem if there is a short. You are INTENTIONALLY CREATING A SHORT. Full stop. Think about that. What fucking moron would intentionally short a device? Get a mirror. What you plan on doing means the ground on that device is ALWAYS LIVE. The chassis is now HOT.There is no real difference between the hot and the neutral in AC system. Power flows both ways on both wires and changes direction 50/60 times a second. There is no difference between tying the ground to the neutral and tying it to the hot from a safety perspective. The only thing keeping someone from getting cooked is that the human body has higher resistance then the wiring does. If something changes that, like your garbage-ass neutral in your shit wiring develops a fault, you now have a light fixture with a live chassis and the only ground path would be through someone that touches it. And guess what? Your neutral just shit the bed so the light is now off. If someone accidentally tries to 'change the bulb' and left the power switch in the 'on' position they will get fucked as soon as they touch the metal of the fixture.And guess what else? Even if that doesn't happen, if a person touching the fixture was to somehow lower their resistance, they could get fried anyway. It takes very little current to stop a human heart. Even if there is a ghetto path to ground in your setup you can still have some current leaking from the fixture through anyone that touches it. Just because there is a lower resistance path doesn't mean NO electricity will travel on a higher resistance one. It just means enough current to kill is unlikely to travel that path. If they did something to lower their resistance, like use their other hand to touch something grounded, enough current could flow to stop their heart.
>>2978412I've been doing that for my AL wire whenever I replace receptacles and switches. I use a wago to add on some CU wire so no AL wire is exposed.You can use a stethoscope to listen for electrical noise.
>>2979625>You can use a stethoscope to listen for electrical noise.I would use an AM radio...
>>2979690I put my house inside a faraday cage. No radio for me. It's a mechanics steth, so it can also help pinpoint where weird mechanical noise is coming from.
>>2979724You don't use the radio to pick up broadcasts. You use it to detect emitted EMF.
>>2979726Oh good to know. I'm going to try to get a job in GE Healthcare and want to work my way up to imaging machines.
>>2979724>I put my house inside a faraday cage. No radio for me.If you're detecting electrical noise, the "radio" is in the house with you.The first radio transmitters were spark-gap devices.The spark generated an electromagnetic wave that could be detected at distance...>>2979727>I'm going to try to get a job in GE Healthcare and want to work my way up to imaging machinesIt sounds like you have a way to go.
>>2979748>It sounds like you have a way to go.Yep. I only have an Associates in Electrical Engineering and only 1.5 classes were relevant and the professor sucked ass, African guy who was too stupid to do so he taught instead.
