    Class B insulation = 150C-(40C+30C)= 80C rise
    Class F insulation = 185C-(40C+30C)= 115C rise
    Class H insulation = 220C-(40C+30C)= 150C rise

    Did you post this info from memory? I think you're off by one notch.

    School was many decades back- sorry

    painpills and insomnia don't help memory either.

    Still that's a good transformer, specs wise
