Question for the gurus. I just tested my housewiring (at the wall
outlet) and found that I have 120V AC between the hot and return,
only I can't tell which of the top two "slots" is hot and which is
return. They both show 59.4 VAC with referrence to the third (GND)
terminal, on the bottom. Huh? Anyone have any idea what might be going on
with my house
wiring? It's an old house, built in '49 or '50, and has had numerous
pieces added and modified. I was in the attic once, installing the
wiring for a bathroom outlet, and got bit by the *white* wire, which
should have been my first clue something was wrong. When I asked
someone else about that though, was told that it might be normal,
depending on what had been put in place. :/
Any ideas or feedback are welcome. Hoping someone can explain this. Also
hoping I don't have to rewire my house...
Floating ground. It is likely that there is no ground wire at the outlet,
and that the origional 2 prong outlet was replaced with a "grounded"
outlet, even though there was no ground wire to connect to the ground
connection.




Hey Bob,

Floating ground... Okay. That would fit with what I saw up in the attic,
about the wiring used in the house. sigh At least it's nothing really
wierd. Always thought I ought to rewire the house, just didn't want to
tackle that project. Wondering if I can live with it...

If done properly, it should be a 2 prong ungrounded receptacle, or a
GFCI receptacle, or downstream from (protected by) a GFCI receptacle. If
downstream from a GFCI it can be a grounded receptacle even though there
is no ground. That could be what you have (but not likely).
