I have no idea what all the abbreviations mean on most of the ampacity charts, such as THHN THWN etc. However I did find an oversimplified one (below ) and based on this chart and others I am guessing between 65 and 75 is the amp rating. I would still like to hear from someone who knows more than I do and understands all the abbreviations etc.
