I noticed corrosion inside one main breaker lug in a panel, called the utility company and pulled the meter, there was corrosion in one load meter lug. Then after the utility co. left, I noticed corrosion in the same side line meter lug. (I'm assuming the same phase as was inside the panel.) I'm going to have the utility come back and check the overhead connection too. Why would white corrosion be only on one phase side of each of 3 lugs? 100 amp service with #4 Copper wires everywhere? Thank you
