An overcurrent is a current that exceeds the amperage rating of the conductors (cable), equipment (motors, instruments) or other devices in a circuit. Without adequate protection, an overcurrent can damage conductors and equipment and potentially harm people. Protection devices, such as fuses and circuit breakers, are installed in a circuit to detect an overcurrent condition and selectively protect equipment and personnel, while minimizing loss of power on the rest of the system. However, the protection device must be properly selected to accommodate the overcurrent and respond in the appropriate time frame.

In this course, the student will study the types of overcurrents that may be encountered and the devices available to afford protection against the overcurrent condition. This course is relevant to electrical engineers seeking a refresher course in overcurrent protection, as well as engineers in other disciplines who wish to expand their knowledge in electrical engineering fundamentals.
