Ratings and reviews

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!

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.

The best program ever that deals with all aspects and calculates them in every detail
