Fuses, Circuit Breakers, Disconnects, Controllers and Electrical Distribution Panels (ECLB# 0803029) - satisfies 1 hour technical (1 credit hours)
This course focuses on fuses, circuit breakers, disconnects, controllers and electrical distribution panels.  One might think that since fuses must be replaced if they fail and since circuit breakers simply need to be reset, that circuit breakers would be the preferred option and that fuses would never be used.   But we know this is not the case.  So, why and when are circuit breakers used and why and when are fuses used?  By the same token, what are the differences between disconnects and controllers and when should each be used.  This course will answer many questions surrounding questions about these components that have similar functions as well as providing an understanding of electrical distribution panels and NEC rules for adding power consuming loads.
