Sorry. I am not sure what the breaking current is. I read something but I don't understand well. In my house I will have 1 lighting circuit and 2 shots. It would also have a pair of TUE circuits. I'm finding out to buy thermal and circuit breakers. As I calculate in those 3 circuits they would go from 16 and 10. But I don't know what brand to buy. That's why the question
The breaking current in a thermal is the ability to "withstand" a short free circuit without being destroyed. For addresses where these currents are supposed to be "small" there are 3 and 4.4 KA. Maybe I complicated it with my clarification of the breaking current but the Domae line will work fine.
