Wire Ampacity Free

This app will calculate the minimum wire or max amps based on the inputted ampacity for low voltage wire. The calculations are base on the 2008 and 2011 NEC code.

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).

See the About menu for more info.
