[Amps] Transformers in series

[Will Matney]

What gets me is why the transformer manufacturers dont use at least a striped and solid wire for each winding showing the phase. All the phase is, is the start and stop of each winding where in paralell both starts are wired together, and both stops are. In series of course this is different. Every transformer I've designed and ordered, I had the phase shown by different color wire. The primary in mine was always white and black. Most use two greys or blacks like the EIA code which I think sucks. If nothing else, use the code and use a striped color for one lead.

Best,

Will
