How is a generator earthed and given neutral?

assegayer · Nov 13, 2017

Hi

I have a question i cant seem to get an answer too.

If you have a portable generator and you plug for instance a fridge or any appliance directly into it, how is the neutral/earthing provided??

I know already that normally you can connect the neutral and earth from an existing installation

But what if you are for example somwhere random and i plug a fridge into a generator where is the neutral coming from? Surely it cannot be from the casing as if someone was to lift the generator up they would get a belt from the supposed to be neutral return path?

Thanks in advance

No, actually, what it 'proves' is that I fully accept you're completely unqualified to comment on matters of electrical safety. And further consolidates my opinion (by dint of the dangerous suggestion you made earlier - that end-users might reasonably construct dangerous contraptions for themselves) that you're a danger to yourself and other people! - The sort of individual that gives Sparks a bad name in fact!

Unfollowing this conversation and the forum generally... Never argue with an idiot it's said; they'll drag you down to their level and beat you with experience! (of stupidity that is!)

Shame, I was looking forward to your explanation as to how 3 phase generation with star point Neutral relates to providing a Neutral in single phase generators.

...Were you? If you were a little brighter - possibly better educated - you'd have understood what I posted earlier. For completeness (and the sake of the hard of thinking) I'll clarify that they don't really 'relate' per se... And that the notion of 'neutral' in a supply derived from a single output coil (such as the secondary of an isolating transformer or the output of a simple generator) is nominal.

I was also quite clear (not that you'd admit it) that I wasn't going to get bogged down in the vagueries of the American split phase system - for the sake of clarity.

I'm sure you're an excellent swimmer and draw superb pictures of Faries when asked - possibly better if you stick to that. Now; do be a good chap and flock the flock off while I figure out how to unsubscribe from this forum!

Hmmm, 12 years at the chalk face teaching how one of the conductors of a single phase generator is made into a Neutral.
Anyone ever mentioned the axiom?
He who can, does.
He who cannot teaches.
