Hot and Cold wires

[Anonymous No.1881368]

I'm installing a garbage disposal and the power chord I got doesn't have a white wire, they're both black. One of the wires has a textured coating though, how do I tell which wire is hot and which is neutral?

Alternating current my dude.

Can still matter though.
A lot of appliances only switch the live wire instead of both, so if you connect them wrong, the whole thing will still be live even when turned off.

The ribbed wire is neutral

[Anonymous No.1881374]

Hot wire is almost always the smooth one and the neutral has texture on it. No idea why tons of those things chose to do it that way.

It literally goes back to "ribbed for her pleasure." If you're wearing a condom, then you can't impregnate her, hence your dick is "neutral"ized.

The grounded conductor should never be switched.

on single phase, only one wire isnt grounded. The hot wire just draws from the neutral sometimes.

You're not smart just because you know neutral is bonded to the primary ground electrode along with ground at the service entrance. Ground is not a current carrying conductor and shouldn't be switched.

And sorry. Anon was not confident.
The ribbed wire is always neutral. The only exception would be if some mouth breathing fuckin retard like you wired it up amd didnt know that's what the rib/texture is for.

I don't get why they call it hot it gives off no heat, so dumb.

Alternating current doesn't mean the "hot" alternates between two wires, retard.

This is more correct. The issue before was using the word "grounded" vs just calling it ground. Faggot.

I guess you've never been in a profession (electronics, electrical work) that require you to differentiate between the primary ground electrode, auxiliaries, main ground neutral, ground (as a conductor) and isolated ground.

I dont make why you think your opinion matters in a conversation about wiring, larper.

>>1883145
He's talking about the chord from the appliance dumbass, not his socket.

In an AC appliance it shouldn't matter, even if it only switches off 1 wire instead of 2, you're not gonna open up the machine and put your hands in there while connected to an outlet.

Any decent appliance switches both wires off.

It absolutely matters. Reversing hot and neutral could energize the chassis even when the appliance is off.

no it cant. neutral =/= ground

[Anonymous No.1883338]

>>1883332
>he doesn't know neutral is bonded to ground at the service entrance

Yes, it can. If you are switching the neutral because you reversed the neutral and hot, you may have a chassis that is energized. If you touch it and ground yourself, you could be injured. This is why you never switch the neutral. Polarity is important in AC because in with an ungrounded plug like a NEMA 1, the design should bond the chassis to neutral because it has the same potential as ground.

What? If your appliance doesn't have PE it needs to be doubly insulated.

[Anonymous No.1883378]

I think maybe there's a problem with the way neutral/ground works in different countries.

In Belgium we have a TT-net so neutral and ground are completely seperated. And we have GFCI in our fusebox so the entire house is protected.


While searching for the image I also found this on wikipedia

> "For a time, US National Electrical Code allowed certain major appliances permanently connected to the supply to use the supply neutral wire as the equipment enclosure connection to ground. This was not permitted for plug-in equipment as the neutral and energized conductor could easily be accidentally exchanged, creating a severe hazard. If the neutral was interrupted, the equipment enclosure would no longer be connected to ground. Normal imbalances in a split phase distribution system could create objectionable neutral to ground voltages. Recent editions of the NEC no longer permit this practice. For these reasons, most countries have now mandated dedicated protective earth connections that are now almost universal."

So I guess americans have appliances where they really need(ed) the neutral connected to serve as ground wire? Does that mean you have TN-C-(S) type net?

You havent been able to bond neutral to the chassis in like 80 years.

[Anonymous No.1883476]

>>1883248
You seem to be the only one confused about ground vs neutral.

Anon said it didnt matter
Anon said it did, you shouldnt wire it backwards because it might make the chassis hot.
Anon said it doesnt matter because ??
Anon said hurrrr dont you know neutral == ground.
Anon said no it really isnt. Ground isnt a current carrying conductor. Yes they're bonded at the entrance, but that doesn't mean you can bond a chassis to neutral, what the fuck are you thinking.
Anon said hurrrr hurrrr I'm smart too, me no dumb

>In Belgium we have a TT-net so neutral and ground are completely seperated.
NEC requires the neutral (grounded conductor) and earth/ground (grounding conductor) to be bonded (electrically connected) at the main service entrance (your home's breaker panel for example).
>And we have GFCI in our fusebox so the entire house is protected.
GFCI (and AFCI) are per breaker rather than the whole panel. Of course, the way the NEC is going, it will eventually require it for everything (which is asinine because not everything needs it).
>So I guess americans have appliances where they really need(ed) the neutral connected to serve as ground wire?
The neutral could/can be used in that way because it is bonded to earth/ground in the breaker panel which is then connected directly to a grounding rod adjacent to the breaker panel. Best example is the three wire versus four wire setup for an electric clothes dryer. For a time, you only needed hot-hot-neutral for the dryer, and the dryer chassis was bonded to the neutral. That changed in 1996. In new installations, you have a hot-hot-neutral-ground where the chassis is bonded to earth ground. However, the code allows an existing three wire installation to remain.
>>1883385
>You havent been able to bond neutral to the chassis in like 80 years.
See the above example with electric dryers. The NEC doesn't require those installations to be updated.

You're just agreeing with me again. Stop being such a moron and just accept it because this is the silliest fucking argument i've been in. MY argument is that there is a distinct difference between calling some wire "grounded" vs calling a wire "ground" or "the ground". The way you're using the nomenclature shows you agree. So shut up.

That's a split phase system yes? You don't have 3-phase or does it differ per state?

[Anonymous No.1883630]

>>1883627
>That's a split phase system yes?
Yes. Residential service in the US is composed of two 120V hot legs 180 degrees out of phase with a center tapped neutral. Commercial and industrial service would be a traditional three phase at various voltages.
