(OP)
I want diagrams on the exact wiring from primary to secondary for all transformer hook-ups.  My text books do not show the actual physical wiring (not theory) that is on the exam here in Massachusetts.  

RE: Transformers


There's IEEE C57.12.70-2000, but that is fairly nasty stuff to have to sift through, and it's not free, and may be considered "theory" so much as quasi-phasors are concerned.  

A contents page of an earlier version is  standards.ieee.org/reading/ieee/std_public/description/dtransformers/C57.12.70-1978_desc.html

Perhaps you could find some locals that will tell you what they've used.

Suggestion: Reference:

RE: Transformers

Try a manufacturer's catalog, Acme, Hevi-Duty, ect.  They give many hardwire examples.  All is a tough term, hope this helps on the practical side.

RE: Transformers


There’s material like federalpacific.com/literature/drytrans/trans.html but it’s maddeningly cookie-cutter in approach, and not likely much help on an exam.
