check your neutral for being loose. cable would be 4/0-3 seu. there is a test for a main breaker but it requires a special instrument that impresses
dc on it and slowly increases amps until it trips - its a time/cycle thing. you couldn't tell anything with either an analog or digital meter. shut your main off before messing with the neutral. as a rule it should be at zero potential, but the neutral also carries the unbalanced load for the house.
