The lead size does not necessarily match the winding size. Most transformers are wound with 700cm of copper per ampere. Range from 500cm to 1000cm has been used over the years. The winding current rating is same as what the transformer manufacture specified.
When some DIYers want to push to limits, should have at least 6 volts with connected load and many consider that voltage under load the safe outer limit, but opinions will vary. Personally, I usually do not push more than 10-15% over specified current specifications. And, I never push HV secondaries. I prefer to load to 50% of the HV current rating and especially so with capacitor input filter.
