NEC Class 2 Power Circuits and Power Supplies

The NEC (National Electrical Code) is a North American standard, which can be regarded as a law in most of the North American states. Among others, the NEC describes the installation of electric conductors and equipment within or on buildings. The NEC also is the source of the Class 2 circuit definition, which limits the max. voltage and current.
