Tim, I do the same thing... Especially after doing a looooong 566' pull of 500MCM for a car dealership rebuild I did with a "past" company I worked for... about ¾ of the way, we found something had penetrated one of the wires straight through!
On this thing, the black above the meter socket is where the wire burned through the conduit... The Edison triplex also melted in places (wierdly, only where someone had put black tape on it)... Even stranger, My hotstick lit up on the grounded phase of the triplex, I've never had this happen before & makes me wonder how well the PoCo Xfmr is grounded... (The Xfmr is pretty close to original for the neighborhood) ...
