I?m sitting here looking at a Talley sheet and out of 24 service up grades, 10 where done by the home owner, 2 where done by general contractors, and the other half where done by electricians.
The electricians consistently do a better jobs, but if I?m to be honest the home- owners doe pretty good. As far as call backs for re-inspections most of the time its things like installing the bond screw, adding grounds rods or, connecting the grounding electrode conductor with in five feet of where the water main enters the dwelling. Electricians get lazy about replacing old corroded water pipe clamps usually the water main jumper.
