Circuit Breaker calculation is linked with the cable which is wrong. Circuit Breakers is independant of cables. Circuit Breaker shall be calculated by using power formula. Cable size calculation shall be given separately.

Thanks for your feedback. In practice, breakers are sized with the cable in mind to ensure the breaker rating does not exceed the cable's capacity.

The app seems good but it's pretty buggy. Unable to contact the devs through the app, nor make feature suggestions because the buttons do not respond. I specifically am looking for box fill calculations. thanks!
