Hi all,
How to make partial or total discrimination for residential use ? I mean how to coordinate the circuit-breakers such a downstream fault (e.g. short-circuit), ONLY the circuit-breakers placed immediately upstream (D2) of the fault will trip. The main / incomer circuit-breaker (D1) remains closed.
My main / incomer (D1) circuit breaker has 25A rating, 4.5kA breaking capacity (60898), C Curve.
Any suggestion ?:|
