Transformers

When you get these industrial diverse power supplies with 400v,230v and 110v sockets on them and there is say a 4kV transformer inside them how are the cables coming out from the transformer connected has to get 230v are the cables connected to the L1 and L3 connections of the transformer in order to get 230v and L3 and Neutral connections of the output of the transformer in order to get 110v and then I assume these cables from the transformer are connected to say a 32A MCB in order to connect to the respective sockets. What is the configuration within the transformer to produce 400v considering that there are 5 power cables each for the L1,L2,L3,N & E that are inputted into the transformer.Quite new to transformers so was after some examples and ideas of the workings of them and what they create in respect of the different line voltages?.Jimmy2Rivers
Do you have an email address I can send you a design of the Power Cubicle cause that is what it is.It's a power source which has 3 different sockets for the various voltages,and inside there are two transformers and there are a set of MCB's above the transformers I assume for safety applications.

I am not qualified to help you design your system.
You really need to get someone in to either look at the system as installed, or the designs if they exist. It's impossible to say what is correct or safe given some vague descriptions of what's there.
HI jimmy2rivers a tough one to er wrestle with , the 110v supply from an on site transformer is I think an unearthed inductive circuit ( I am learning electrical work at the moment) , this so that if you do happen to touch any exposed conductor , you get a shock but it trips . the 240v and 415 v outlets I have seen often on onsite transformers, and as far as I know they are different to 110v outlet , so I assume they are transformed separately and probably L1 ,L2,L3 for the 415 and one phase spurred off for 240v... hope that helps
