There are two basic methods of circuit protection: fuses and circuit breakers. This course explains how these methods of circuit protection prevent too much current from flowing through an electrical circuit. Starting with a clear demonstration of the basic theory upon which these devices are designed and helpful definitions of terms commonly applied to them, this webinar shows why these protection devices are so important to engineers who, by the very nature of their work, are exposed to various problems and dangers resulting from the use of electrical energy.
Among other things, we will discuss both fuse ratings and circuit breaker ratings. Fuse ratings include current (which is, after all, what causes fuses to open), voltage, amps interrupting capacity, and other items. Circuit breaker ratings include these same factors, but unlike fuses, they are resettable after a trip incident. Since there are places where either fuse protection or circuit breaker protection will be more appropriate, you will learn the advantages and disadvantages to both methods of circuit protection.
Additionally, we will examine the selective coordination of complex circuits for large buildings or industrial facilities. Selective coordination means that, when (not if) a fault develops, only the part of the circuit involved in the fault should be disconnected. As a result, power will remain available for the rest of the facility. Another way of saying this is: A protection device (fuse or circuit breaker) should only operate if it is directly involved with the fault; upstream devices should be sized so that they do not trip or open when the device directly downstream of them opens.
Special Note: Course E-4013 and course E-2089W are alternate presentations of the same course material. Therefore, only one version, either the course or webinar, can be taken during a renewal cycle. If you have any questions regarding course eligibility, please contact our Customer Service Team. This course is a recording of a live webinar.
