Fine line between a heavy overload and a dead short.
If the main is tripping and the branch is not, you can be pretty sure
it is NOT a dead short on one of the branch circuits - - - -
Good assumption. But in my case, when I turned off all breakers and
flipped them one by one to locate the offending breaker, I always found
one breaker (different ones on different occasions, a total of four
breakers) that, when flipped, would trip the sub-main breaker.
Also, as I stated in another post, I have a total of 10 lights, three
refrigerators, a water heater, and some small gadgets such as TV, DVD
player, etc. There is no way they would overload a 63A, 220 V breaker.
What is the rating of the branch circuit breakers?
