Guilty, what can I say, but I really can't escape the feeling there was a topic somewhere about some impossibility of having two primaries in a transformer. Maybe there are some crossed neurons somewhere. If so, I'd rather have that checked after I'm gone.
It's not only you, by any means. Transformers come up here quite often, and I always try to respond because it's clear that many do not understand them. But just like 'Upload to Files => Temp' doesn't seem to register, neither does the transformer 'lore'.
What you may be dimly recalling is something about having two generators feeding two separate windings. It MAY be OK if the numbers are right, but it MAY produce huge currents.
For example, suppose there are two identical windings and 10 V is applied to one. 10 V will appear across the other one, too. Now connect a 100 V source to that second winding as well, and watch the pretty smoke.
