References: NEC Article 31 and UL 508A. Also see CEC and appropriate Canadian Standards. Both of these factors are proportional to the square of the current. Thermal energy is proportional to the square of the RMS value and magnetic forces are proportional to the square of the peak value. The most effective way to provide
