Details, formula, and sources
Typical full-load amps looked up by horsepower, voltage and phase from figures compiled across NEMA-aligned manufacturer technical bulletins. Not the NEC table values, which are licensed text this project does not reproduce.
NEC 2023 (NFPA 70). Sections 430.6(A)(1) and 430.6(A)(2) by name; manufacturer specs as of build date.

- Not the sizing value NEC 430.6(A)(1) requires the Table 430.247-430.250 value for conductor and overcurrent sizing, and 430.6(A)(2) the nameplate FLA for the overload device; these typical figures are neither. Until 2026-09-02 this page said they stood in lieu of the tables, which is the opposite of what 430.6 says.NEC 2023 430.6
