Figure 1 One or more attachment points 118 of the circuit breaker housing 104 of the circuit breaker 102 are engaged to form Figure 3 Assembly system 100. The orifice body 122 includes an optional gap region 126 configured to allow access to and operation of the switch 106 of the circuit breaker 102 when the orifice body 122 is engaged with the circuit breaker housing 104 of the circuit breaker 102. In configurations where a gap for the switch 106 is not required, the gap region 122 is not necessary. The orifice body 122 includes a test or reset button 128 configured, for example, via a connector 130 of the mechanical switch 106 of the circuit breaker 102 (in... Figure 1 The orifice cover module 120 (marked in the center) mechanically interfaces with the test or reset mechanism. The orifice cover module 120 may have a different color than the circuit breaker housing 104, and multiple orifice cover modules 120 in a single circuit breaker panel may have different colors from each other, serving as a visual coding or organizational tool for the end user. It is also conceivable that the orifice cover body may include a service LED 129, which can be used as an indicator of advanced functions of the circuit breaker 102; for example, when the user presses the test or reset button 128, the service LED 129 may flash different patterns, where each pattern signifies something different, as described in the instruction manual.

[0026] Now for reference Figure 3 The cover module 120 is engaged with one or more attachment points 118 of the cover connector.
