Easy / safe tests to detect problems?


Question for the pros - are there any safe ways to preemptively test for things like EGC/neutral problems? Some thoughts that occur to me:


1. Shutoff main breaker and measure for voltage on the EGC system (specifically water pipes). If you find voltage that would that indicate a problem at someone else's house feeding in through the water pipes?


2. Turn main breaker back on and turn on load at end of each circuit. If you measure any voltage on the EGC that differs from #1 then it would seem you have something wrong somewhere with either a loose neutral, bad fixture/appliance, or an inappropriate EGC/neutral bond. Is that right?

3. Measure voltage across hots and neutrals to ensure ~120 volts. If high or low, could also indicate a loose/lost neutral?


If so, seems like an easy and safe test that a homeowner could do preemptively to look for a problem before it becomes dangerous?

Does this make sense or am I just totally batty?

you cant really do preventative testing as the test may be fine today and fail tomorrow. I would recommend periodic system maintenance. We offer a home protection plan where we come in on a yearly basis and test GFIs tighten panel lugs and breaker connections test polarity of outlets and do a visual inspection of devices and exposed wiring in attics ,crawl spaces and basements.

Sounds like a rip off to me.
