Re: Quick-and-dirty testgear: mains voltage monitor.
Surely the reason TNC-S is so widely used in spite of such an apparently dire failure mode, is the fact that the multiple redundant connections make it so much less likely to fail that way in the first place?
Which leads us to the interesting question ..... How are the homes of the families of the utility company executives wired up?
