Abstract A circuit breaker was examined to determine how it works. Basically, it is designed to disconnect the current if the current passing through the breaker is higher than the allowable current. Its main parts consist of a switch, connecting pads, and the disconnect device. Since the breaker consists of many individual parts, the only improvement found was to combine some of the parts into a single part. Introduction Our group dissected a thirty-amp household …

…The circuit breaker's best point is that the device is effective and compact. On the other had it is not 100% effective and must also be manually reset which can be problematic if it is dark and no lights are available with which to see the fuse box. Another bad point is that the circuit breaker has many moving parts, which complicates construction. Simpler or fewer parts might drive cost down and make manufacturing more efficient.
