Episode: Electrical Myth - Wire Length Code - Short #155
Description: In this short podcast, Bryan covers a common electrical myth about wire length and its relationship with the National Electrical Code. The NEC is concerned with safety—protecting buildings and people—but less so with making sure things work. Wire sizing is a common topic, and length is important because it can contribute to the voltage drop in a circuit. In many cases, we refer to the MCA (minimum circuit ampacity) to select an appropriate wire size. If you run more current through an undersized conductor, it gets hotter and will experience a voltage drop—though...
