Does Single Phase Or Three Phase Require a Neutral?

Also, how does the neutral work on a phase system?

Single phase requires a neutral.
Where there is a neutral on 3 phase, it is usually there to allow one or more of the phases to be used as single phase.
For instance many machines are 3 phase, but will have single phase controls and indicator lights, another example would be where a 3 phase supply is used to feed three separate flats, each flat using one of the phases and a neutral.

Because all of the elecktrickery is used up meaning there's nothing left to power the neutral. Single phase or unbalanced 3 phase systems don't use all the electrickery and need a neutral to send whats remaining back to the grid for recycling

Go easy (some of you). Sounds like a kid at school with a question his teachers can't help him out with.

I'm on my second year at college studying electrics. It's very rude for you guys to say that.

Looking at his other posts, it looks like someone still in college. Just asking a question.

Maybe it is time another board was created for people at college to ask questions, then hopefully they wouldn't receive abuse for some questions they ask.

That was talked about a few weeks back, everyone agreed it would be a good idea but nothing happened

 

[Plonker 3]

I know, maybe we should do something more pro active to make it happen ourselves then?

 

[MattyH]

Still though. People shouldn't be so rude. Seeing that some of the guys who said the abuse are admins aswell? It's really embarrassing for the forum.

Unfortunately some folk don't always look at who has posted the question. Please don't let it put you off the forum as it is a good place to learn from and there are some very knowledgeable folk on here who will be more then happy to help you.

I am sure I have made similar comments in the past, I am ashamed to say. But would like to think I know better know.
