I can't verify this as I was out on vacation last week . We have a test stand that has 2 ( 75 hp ) driven pumps on it . This is across the line starters . The operators claim that when they shut the pumps off ( yes they claim when they shut them off ) that the 400 amp molded case circuit breaker " SQ D LA36400" that feeds the busway that feeds the stand tripped . The trip settings are at mid range .They say this happened 3 times last week . My boss has ordered a replacement breaker but I have doubts that the breaker is the problem . Any thoughts on this ...
