Kevin,
The following should be considered when reading the Loading Guide:
1) The loading guide assumes that the transformer's life is determined by failure modes based on chemical reactions. This is true for many of the important failure modes, e.g. paper degrading, but not true for some other...

Thank you in advance for your assistance.
