no offense taken and that’s what Im sayin one day this breaker is going to get weak and fail or someone will throw it against a real permanent fault. As for the genset taking a beating would it not be isolated since the t-switch is open on that side at that time in the transfer.As for the t-switch I bet it can't be good.I was once told years ago that this is not an uncommon problem and an accepted remedy was an inphase monitor.This was a recommendation by the manufacturer of the t-switch.Almost forgot we had respected contractor who specializes in this come in and put in place test equipment to record the fault while doing the manditory CSA full load bank test.The system passed with no problems and we were given the green light to a building load test today.Guess what happened.
