Field notes
The collection separates design and sizing, raceway and enclosure, power conversion, and electronics tasks rather than presenting one undifferentiated calculator. Its examples include Chapter 9 conduit-fill limits, Article 314 volume allowances, transformer primary and secondary FLA, and Peukert correction for battery runtime. The homepage also says the tools retain offline operation after loading.
