Size Transformer Feeders Differently than Other Feeders
Allow transformer feeders to be sized using different size wires than other feeders. In particular, this would be for sizing 800A feeders. Normal panels can use 500kcmil wires, but transformers require 600kcmil.
(The workaround for the moment is to use 500kcmil for your 800A automatic sizing and to manually size the transformers to 600kcmil.)

Similar to the workaround, we have created a new wire sizing entry and included text in the "Description" to indicate it was for transformer secondaries to help speed things up.
