Customer was having an issue with the range circuit tripping when she would use the oven and a top burner at the same time. I turned everything on and found that the aluminum wire was over heating causing the breaker to sizzle and arc internally. We ran a new 6/3 copper line from the main panel up to the kitchen behind the range and installed a new 4 prong 50 amp plug. We replaced the 3-prong cord on the range with a new 4-prong 50 amp cord and installed a new 50 amp CH breaker to power the range. Once completed we turned all the burners on as well as the oven and it is working properly. .
