I have a friend whose mother-in-law's main breaker burned up, due to a loose connection. We had PG&E come pull the meter so I could replace the bad breaker. There was only minor damage to the buss bar, I pulled all the breakers out of the panel and cleaned the bars of any carbon deposits. I replaced the damaged breaker (GE, I believe) with a similar breaker (Homeline), which was the only suitable replacement I could find in our town without buying a full load center. PG&E came out to replace the meter, then pulled it back out. A customer service rep called my friend (who owns the house) to tell him that "according to the notes" she has, that I used the "wrong breaker." That was all the detail she could give us. Any idea what they're looking for here?
