A great tool for electrical engineers and electricians.
This app will calculate:
The minimum wire or max amps based on the inputted ampacity for low and medium voltages,
The equipment and service ground size
A residential feeder size
Note: The app is called Wire Ampacity and not Circuit Ampacity. This app does not specify the size of an over-current device, simply the AMPACITY of the wire (i.e. #14 75 degree wire has an ampacity of 20A, but should not be used with a 20A breaker).
The calcs are base on the 2008/2011/2014 National Electric Code (NEC).
See the About menu for additional functionality.
