I lost count of how many 100 and 200 amp service entrance cables I
replaced because the cable guys just decide to drill their hole next
to it without checking inside first. I guess they can't fathom the
idea that you can run entrance cable in directions other than straight
ahead. If by some chance they missed the main they were still fond of
drilling through various other wires. Of course they always do this at
3PM on a Friday.
