General:
Not that I have any links to share but any sources that explain how to properly use some more specialized tools/equipment, when they should be used, when they shouldn't be used could fall under the category of "working safely."
As an example:
I found that the little "non contact electrical current" tester pen that I bought recently and have been trying to use to do home repairs has some caveats about when it will give a false negative. I had skimmed dozens of "how-to's" and only a few of them mentioned that using this tool to check electrical outlets won't work if the outlets aren't properly grounded (I live in a shitty shitty house, a chunk of the problems wind up being things not done properly). And I think the same thing might apply to checking Romex cables but I haven't spent the time to try to find out for sure.
Thanks for this super helpful comment! I had no idea that those pens required proper grounding, but I suppose that makes sense.
From my understanding, you'd need a multimeter to check the grounding. While the pens might be handy, unless you've previously confirmed the grounding, they don't seem especially useful.
Yeah... who woulda thunk it, not building things to code causes problems down the line? Not my in-laws that's for sure!
