Yes, oops, I read that as overcurrent when the post mentioned not using secondary protection, so that would be 125% minimum on conductor size.
But Bill, the wording on 26-256 refers to rated current of the transformer, so you wouldnt limit current on the secondary conductors to less than the KVA rating of the transformer unless you wanted to do so, since 125% is the maximum, you could go less if you chose to.
