Field notes
Ampxa separates common electrical calculations into dedicated pages rather than presenting one general-purpose form. Its stated workflow combines user-entered quantities with equations and assumptions, while code-table values such as conductor ampacities and raceway dimensions are not reproduced on the site. The project also signals a broader contractor workflow in development, with box-fill, load-calculation, conduit-body-sizing, estimating, and invoicing features listed as forthcoming.
