wire coupler
>and why is it needed
couples wires together. Have two wires, want them to become one wire? Wire coupler.
>>994402
Also called a wire nut.
>>994431
looks more like a crimped connection vs a wire nut
>>994389
>what is that white knob(?) and why is it needed
its a shame that people today are so fucking stupid they dont know what a wire nut is..
>>994446
If you pulled your head out of your ass you would have noticed that USA is one of the few places where these things are commonly used. The rest of the world prefers proper reliable connections and solders their shit.
>>994450
these are used in other places besides the US you dumb fuck
>what is that white knob(?)
I'll tell you what it is, it's utterly fucking illegal everywhere except in america. Nothing causes more housefires than wire nuts, to such an extent that everywhere has banned them for use in residential applications and insurance companies may check for them and raise your tariff in industrial uses.
I don't give a shit if the US tells me they're safe, they aren't. If you've any sense, use them only on low voltage.
>>994473
>not safe
lol you dont see every house and busines in the US on fire because of these. you are a stupid fuck along with the other dumbfucks who say these things arent safe. this has to be a fuckin troll thread people cant be this fucking stupid
>>994471
Like what, South Africa and Straya? Burgers, niggers and bogans. Way to go.
The only way to make a connection worse than using a wire nut is just rat-tailing it.
In places where housing isn't disposable and real voltage is used that shit is illegal.
>>994450
No i dont think anywhere solders their mains electrical connections.
Well I've taken apart a lot of different devices and never seen one in my life (I live in Sweden). Seems pretty retarded after reading up on it so I threw it away.
>>994475
If you can't understand why loose intermittent connections aren't safe then maybe you're the fucking stupid one?
>>994438
It is.
>>994450
You don't solder mains.
Not trying to fight, but if you don't use wire nuts to join mains voltage electrical connections, what do you use? I can't imagine someone soldering wiring in junction boxes. Legitimately curious.
Also, when installed properly, wire nuts are secure. When improperly installed they can become loose.
>>994520
The problem is people thinking that wire nuts make loose intermittent connections.
>literally thinking that the poor wire nuts used 50 years ago are the same as used now
>pretending that wire blocks are any less dangerous if they come loose
But hey, the same exact people who defend having a hot tap and a cold tap in their sink.
Thats tradition!
>>994450
Holy Jesus please forgive us for this faggot
>>994473
>not safe
Any point where wires connect can be weak. I've had terminal block go bad, connectors, contactor connection points, yadda yadda. There is nothing that is perfect. Any good electrician gives wirenuts a good tug after applying them, then another quarter spin.
So wirenuts are bad and you don't solder mains then what is the absolute securest way to splice cables?
They are completele shit, illegal In Australia too. To the bloke that was curious we use screw connectors, nicknamed 'blue points'. America also wires there shit using solid core cable, yuck. For the application in op's pic, would proabbly use a crimp.
>>994553
hot glue
>>994554
>America also wires there shit using solid core cable
>paying more money for wires that are larger for the same payload, that are susceptible to corrosion, harder to terminate, and can fail at terminations
This is why I love Diy, tons of insults and laughable garbage but you always get an answer. Stay classy
>>994553
cut the whole mess out and replace it with one solid cable... but thats wildly impractical....
>>994559

The nanny state of the UK all outlets are illegal in a bathroom.
Did you know its against code to actually have a regular lightswitch in the bathroom there too?
Pullswitch lighting is the best!
Coding laws from 50 years ago sure are great arent they?
>>994568
Yeah...no I went for the hot glue solution and self-vulcanising tape.
It's clearly an end splice crimp terminal. I swear you idiots keep getting more stupid.

I mean its about as much of an argument as anyone else has made.
>>994569
a 'regular' lightswitch is not against 'code' in a bathroom or anywhere else the uk but it must be outside any 'zones', if it's 60cm away from bath/shower/middle of basin then you are golden.
outlets are exactly the same
and they are not illegal. you wouldn't be arrested for breaking the rules. police would not be called.
if you break the rules then the work won't be signed off and you won't have a certificate when you sell your house. but literally nobody will care and nothing will happen. but if someone dies and they can prove it was your negligence (the rules are mostly sensible and there to protect rather than stifle) you might get fucked.
most electrician will not feel comfortable putting a non ip or ELV rocker switch or a bs1363 socket inside a bathroom because of the potential hazard. and do you know what? nobody minds.
>>994554
> Needing a screwdriver
>>994484
>Straya? >The only way to make a connection worse . . . real voltage is used that shit is illegal
- pretty sure they don't meet any required standards in Australia : I think they're only sold in Bunnings and even then only for speaker-wires.
The only thing allowed here 'since for ever' is screw terminals.
For example If you buy a terminal-box it will always have a three [or four] screw-terminal inside it.
And I think Earth-wire soldering went-out in the 1970s , due to brittle-ness.
>>994450
It really shouldn't take anything more than a critical eye to figure out what that thing is.
>>994695
Soldering any wire in a fixed installation in Australia is legal however any insulation removed must be replaced or made better and the actual solder joint shall be supported so that the joint is not subject to mechanical stress. In addition the solder is only to hold the copper strands together, so the splice must be made in a way to give sufficient contact and mechanical strength and then the solder is added.
Soldering sub circuit earth's to the main earth conductor is legal and was common practice but no-one does it because electricians are lazy cunts and would rather do up a screw, I personally dislike soldered connections in a fixed installation. Best would be crimped lug with bolted connection.
Or rat-tail that fucker to oblivion (it always works)
>>994662
>poorly installed wire nut
Anything poorly installed will cause problems.
>>994665
do you think it just might be possible that perhaps the hydraulic system was controlled by electricity?
also, it's called a screw terminal you swine
>>994772
No hydraulic system is controlled by electricity without failsafes.
>>994776
Probably built by dirty indians
UK outlawed wire nuts because of the old ceramic ones that sucked. Plastic ones used now are perfectly safe if you're not retarded and/or living in a nanny state that over-regulates everything.

Also why would it be bad to solder mains, providing you use shrink tubing and provide stress relief if any dumb fucker comes around pulling cords?
>>994473
In the last 50 years, there has never been a house fire in this area attributed to wire nuts. Where do these fires occur that these are supposedly so dangerous? Seriously, where are you getting your information because if I see studies that indicate a significant danger, I will stop using them.
>>995716
These mongoloids are going off of the horror stories from almost 70 years ago when all wire nuts were made out of ceramic. They would break and could potentially cause a fire.
Instead of acknowledging that things change, they hold onto grudges because their grandfathers told them to.
>>994536
Back in the old days they did, they didn't have wire nuts. you had a laddle of solder, some rubber tape and then you would put cloth tape around it.
My house was built in 61' and it was done this way, I also have a rental built in 56' that was also done this way. There's nothing wrong with it, and it's still permitted by code. If anything, it's a better connection, since wire nuts can come off if not done properly.
>>994536
Why? Serious question, looked it up but couldn't find anything

That's totally reasonable... How the fuck did they manage that?
>>995386
they aren't specifically outlawed its just nobody used them because they were shit.
professional electricians take pride in their work here and don't jam wires and cables in willy nilly higgelty piggelty they like to arrange them neatly and properly. you can't do that with wire nuts like you can with screw terminals or even the new push connectors where every wire has its own hole.
>>995714
>rovide stress relief
it wouldn't but good luck. soldering isn't considered mechanical strain relief. also you would have to carry an iron around with you and considering the size of mains wiring (especially US piddly low voltage = high current wires) you would need a proper iron.
Soldering along with crimps aren't required to be accessible for maintenance like screw terminals so you can bury them in walls if you wish.
>>995754
taps are thermostatic and mixers where you need them (kitchen sink, shower etc) you don't need mixers in a bath or basin so why install them there?
>>995776
it has been relaxed in recent editions, the rules used to be a little stricter. there are also weird things like you can have a socket in a cupboard within the 60cm but the cupboard has to be locked using a 'tool' (i.e. a key or a screwdriver or something). seems like they went out of their way to be helpful to people in bathrooms.
>>995713

What countries use solid core? Literally all of them below around 30A

>you don't need mixers in a...basin
Yeah 'cos I love scolding my hands when I try to wash them with just the hot tap.
Seriously, I'm a bong and not having mixer taps is just fucking retarded. It isn't 1947 any more.

Not when you're putting them in the wall you poofter. Those are mains. From the wall, the cords are stranded, but not in the damn wall.

is burgerland 120v low voltage?
because literally every socket in my house uses wirenuts and they just werk
>>995711

>>996406
Also the hassle of creating termite
>>996405
To the lineman anything below 500v is low voltage.
I've also never seen a bad wirenut in my life.
And op's pic isn't a wirenut, the anon is a weekend warrior that doesn't know his ass from his hole in the ground.
To anon electricians, I think they generally consider 12v and under low voltage? Some guys even shit their pants at 50v.
>>997407
What's that in op's pic IF not a wirenutt?
>>997407
It's a fucking ceramic wirenut - they were superb but don't see them now except in older properties.
>>997549
Actually I'm wrong - it's a plastic covered crimp terminal. Does the same thing as a wirenut though.
>>997407
Low voltage is closer to 1kv
Extra low is ~50
USA electrical code is the only one that puts>50v as high voltage.
These are only supply system classifiers but why do you need anything else.
