[QUOTE="netblindpaul, post: 122762, member: 7384"] I took the board to be an MCCB incomer with MCB outgoers? MCCB = Moulded Case Circuit Breaker. MCB = Miniature Circuit Breaker. Typical breaking capacity for MCB circa 10kA (max) Braeking capacity for MCCB perhaps 35kA. Little different! O) If you are interested look on the Schneider group site and you can download some data giving examples of how to achieve discrimination between such devices. Discrimination is a complex field and it can be total or partial depending on the CPD's. Hence my query about Amtech software elsewhere. Discrimination can be VERY important on large multi DB installs. You don't want a lamp failure taking out half a production facility employing 100's of people because you got your discrimination assessment/studies wrong! [/QUOTE]
