[ad#block]Question: What is the internal connection of a 220v breaker? Does it trip only if current over its rating is detected phase to phase? Also what is the internal connection of a 3 phase breaker? A 20A 3 phase breaker trips if over 20A is detected between any 2 phases? Or do both of them detect over current of individual phases to ground?
