Fix the wire size and it'll be great

Yeah, the ampacity/ wire size part doesn't give the wire size, but the rest works great. Fix that, and 5 stars.


Qualified Electricians only

As a 20 year veteran in the electrical industry I must say for small quick calculations this app is great again it is only for skilled electricians or engineers you must understand the NEC!!😋GREAT APP Electricity is NOT a hobby

Needs work

Wire size does not function, no data is displayed after selecting the amps, and temp ratings. Email function on wire sizing page causes app to crash.
