I have a friend who was asking me about a problem he is having in his house. He keeps tripping 10 amp circuit breakers, especially on the freezer and micro wave circuit. First, I didn't know it was acceptable, especially in a newer home, to use 10 amp breakers. I cannot find in the code where it states that you can and what wire size to use. Is this acceptable, or should the breakers be changed, if the wire size is correct?
