I accidentally drilled a hole in the service entry wire a few months ago. Other than the light briefly flickering when it initially happened but other than that I hadnt caused any problems at all. I know I got extremely lucky! I got a quote from an electrons of 925$ to replace it but Im wondering if it needs to be replaced since it hasnt caused any problems?


My father had an underground cable to his shop that failed. I traced the
problem to just outside where the cable went into his basement using a
multimeter to probe for current leakage. The problem was that the cable
had apparently had it's insulation nicked during installation, and the
aluminum conductor had completely corroded away. The electrician that my
dad hired to fix it used 3 rolls of 3M electrical tape to cover the repair.

And it will likely fail again.
Forget the Likely - it WILL fail again . 3 rolls of tape won't make
it any beter than one. It needs a "self vulcanizing" or "self sealing"
tape, or better yet a jell filled connector. Undeground cable
connector kits have a gell-filled heat shrink tube - 2 layers. When
you heat the shrink tube the tube shrinks and the jell melts and
squeases out the ends. The second longer piece goes over top and
double seals the joint.
