What does happen when reverse the BAT(LINE) and AUX(LOAD) wires of the circuit breaker ？
Reversed circuit breaker's wire connection maybe decline interupt capacity.
The main role of the circuit breaker is protected the device when circuit short, if wire connection is reversed, breaking capacity of circuit breaker maybe drops, when short-circuit comming, the high current exceeds the rating,the circuit breaker can not be break, it will destroy the device, serious will cause the circuit breaker to explode. That is why the wire connection of the low-voltage circuit breaker cannot be reversed.
