User reviews

Good

Is there a way to get it to display in cu/in? Then it would be perfect. I figure there is but I don’t know where that setting is. I have a iPhone SE and it displays a little crowded.

Doesn’t calculate accurately

This app does not include calculations for your equipment grounding conductor, barriers, wire loops, and terminal block fill.

Imputing information into the “largest attached wire to device” is not clearly explained.

Needs instruction.

Update to current code cycle.

Not bad

Needs to have more wire size options. 14-6 only
