You know, that had always been one of my greatest worries as an electrician/contractor. Even doing small service work, and finding existing problems near or part of what I was working on, darn near gave me nightmares each night. No matter how far I tried to repair things, there had to be a stopping point, either by customer request or financial reasons. I couldn't afford to re-wire every other house or business I worked on. So, I fixed what I could, and fervently hoped for the best of the rest.
