110V site transformer

[markym001]

Hi all,
I'm new here but looking for some help with wiring a site transformer.

It has a 32A 3-phase supply. I can see the terminals where I wire the phases in to but I cannot see where I need to connect the neutral. The transofrmer will be dropping the voltage to 110V.

Where do I connect the neutral to? All help will very much appreciated.
If you ned any more information then please let me know.

Thanks in advance,
Mark

If the primary is delta wound it will not have a neutral connection so you need to check the primary configuration

Thanks UNG
How can I tell if the primary is delta or star? I do not have any paperwork for the transformer.

I have got the transformer working - thanks UNG. Could anyone please explain how this works without a neutral from the 3-phase supply.

Many thanks.

NO Neutral required Having done 100s of site trannys put an earthclamp(bad practice I know) on your swa as when OINKS on site move tranys they dont care or notice that they have disturbed your gland and an earth clamp will at least keep the swa earthed Im assuming you are using 4core swa

Ask yourself, what is a neutral ? and why, or where would you need or not need one !
