I discussed this with Peter Dahl when ordering a transformer which I 
wished to use both here and in a 50-Hz. country.

He explained that, especially as transformers get larger, a 50-Hz. rated 
transformer will have much more iron in it. There is no problem using 
such a transformer on 60 Hz., but a 60 Hz. transformer used on 50 Hz. 
will draw more current at idle, heat up and burn out.

The roughly 3.5 kVA transformer that I ultimately ordered weighed 30% 
more than an equivalent one rated for 60 Hz. only. He assured me that it 
would work fine on 60 Hz.
