if this house wasn't slated for demolition in several years (no one in the government can coherently say when, only that it is. they used to say this year but then they did cosmetic repair instead, because that makes sense) I would literally just replace all wiring and appliances

to recap: the brown wire here is -neutral-, and blue and green-yellow are switched, and normally hot because they're energized through the lamp. the G/Y wire in the junction box misses a chunk of insulation in the middle, too, just for kicks

I don't think I can tear up walls here so I did the next best thing: switched G/Y to be neutral and indicated the real purpose of wiring with a heatshrink sleevepic.twitter.com/nsTr0RYI8u

when they say "you can twist copper" they don't mean twist LIKE THISpic.twitter.com/B9WDoV0yNn

in case you thought this thread can't get any worse, we have a code violation bingo! behold: exactly 5cm of copper wire extremely badly twisted together with decaying aluminium wire. there was enough length to not do this extension, he could have just put the junction box higherpic.twitter.com/Daf8q70v2H

also the decaying aluminium wire was load-bearing: the junction box was "fixed" to the wall with a single screw (naturally, not going through the hole specifically meant for a screw) but mostly held in place by wiring

by the way, directly above the load-bearing junction box with the aluminium-copper twist there was a polystyrene foam ceiling tile, glued to it badly enough that it fell off and is now solely supported by wiring that rests on threads of screws mounted into the wall

I mean, saying that the aluminium-copper twist was "in" the junction box is doing it a favor. it was "near" the junction box. "in the general area" is perhaps a good way to describe it.

more photos of the mystery junction box. looks like there's another generation of wiring going somewhere... down. I do not know if it is hot, and I dare not check. I do not know where it goes eitherpic.twitter.com/UQ7G9w81BD

as you can see, this junction box has three exposed wires. left to right. 1: neutral. 2: living room ceiling light 1. 3: living room ceiling light 2. 4: bedroom ceiling light and -all bedroom sockets-. yes. the ENTIRE BEDROOM, including SOCKETS is designed for SWITCHED NEUTRAL.

*wakes up* i'm this close to giving up. not because i can't fix this--even more depressingly, the fix is near trivial far as i can see--but because of a severe, life-threatening shortage of even. specifically...

based on the appearance of the junction, either the original builders set up this switched neutral thing, or someone else after them has deliberately (you can't do this accidentally) swapped phase and neutral in the main distribution box and i don't know which option is worse

i will never make fun of anything related to computers again because no thing in the entire history of computing was done as badly and as hazardously as wiring in this house yes, i know about therac 25. this is more like a fractal therac 25.

I opened the only circuit in the apartmet with apparently intact grounding and not only the copper wiring is improperly terminated (it ah... fell out when I opened the socket), but also the protective earth is broken in at least two independent points

no, ${anonymous_electrician_who_i_know_for_sure_has_a_state_license}, you do not crimp wire ferrules with -pliers-. not now, not ever.

well this would certainly explain why a correctly wired socket in the kitchen had phase on the proper contact in spite of the cable going to the distribution box being connected backwards (phase and neutral swapped) same licensed electrician btwpic.twitter.com/JTaOvNLSxD

please note the single screw that pretends to keep it in place and, yet again, load-bearing wiring
এই থ্রেডটি দেখান -
to be clear, yes, the multistrand copper cable from the distribution box goes through the bathroom socket, is poorly squished into a socket that is designed for singlestrand copper exclusively, and, after going through socket contacts, swaps phase and neutral and continues on
এই থ্রেডটি দেখান -
well, and -this- would certainly explain why there's an earth fault. the ... creature who did this part of wiring removed the insulation with a knife on all of phase, zero and ground, phase shorted to ground and burned it off. no GFCI, nothing to prevent thispic.twitter.com/wBjMoGG1LH

I thought the sixty year old aluminium wires twisted together with copper wires that melted into a blob stuffed in a screw terminal would be the worst I see here but the ten year old completely new wiring somehow manages to be even worse

I could literally replace all wiring in this apartment with one huge extension cord christmas tree and it would be less hazardous. by a large margin.

have some more load-bearing aluminium wiring in a screw terminalpic.twitter.com/e0ps3WTKyK
