Glossary 31
the current capacity is limited by an overcurrent device, such as a fuse, or by the inherent capacity of the
secondary transformer or power supply, or a combination of a secondary winding and an impedance. A
circuit derived from a line-voltage circuit by connecting a resistance in series with the supply circuit to limit the
voltage and current is not identified as a low-voltage limited energy circuit. or has been tested and found
suitable for a specified purpose. (Source: NEC.)
