The first one for RCBOs common busbar and the second one for RCD and common busbar for associatedMCBs. Now, connect the output Neutral wire from the main switch (as blue color) to the common Neutral Busbar terminal in the consumer unit. The resistor passes more current than that required for tripping, and the duration of the test is not limited, so testing in this way does not provide proof that the unit is working to specification. For load circuits wiring, there are two terminals on the output side of an RCBO viz Phase and Neutral. Another way to protect circuits under the 17th Edition IET Wiring Regulations is by fitting Residual Current Circuit Breaker With Overload (RCBOs) to every circuit, and although this is more costly than the RCD+MCB's option, it means any fault condition on a circuit trips only that circuit's RCBO, so the search for the fault is narrowed down from the start. In addition, the earth wire should be connected from the main earth terminal. When the MCBs are clipped onto the DIN bar, the bus bar is inserted into the live terminal at the bottom of the MCB.
