The circuit breaker module for this design project is a proof of concept that demonstrates the functionality, feasibility, and attainability of a consumer grade power systems analysis device suitable for college laboratory use. The goal of this project was to create the final iteration of a module that has been developed and refined over the course of previous years. The Cal Poly Electrical Engineering Department intends to use this design to produce circuit breaker modules intended for fault analysis. With the current changes made to the previous modules, the current circuit breaker is lighter, safer, and more universally reproducible. The use of a generic plastic enclosure ensures that others outside of Cal Poly may find the means to build this module themselves. The redesign of the faceplate was done to prevent module users from touching exposed live wires when trying to reach the mechanical switch. Finally, more affordable, adequate component alternatives were found so that Cal Poly will be able to reproduce this design for years to come.
