My father-in-law replaced a 15 amp circuit breaker with a 20 amp circuit breaker a few weeks ago. This breaker is for the outlets in our living room as well as one outlet in our kitchen so it serves lights, a television, dvd, CD, and our refrigerator. Yesterday, I set up our Christmas tree and plugged in all the lights for the tree as well. 5 hours later, the breaker popped and when I flipped it, it popped again.
Is the problem the 20 amp breaker?
