I have an outlet on a glassed-in porch which is connected to the GFI
circuit. Everything else on the circuit works, I have 110 volts at the
outlet, but even a small lamp will not work when plugged in. Love to
hear any ideas about troubleshooting it. Tks. Pat
Shouldn't be. How can you tell that you have 120 volts at the outlet? If you
test between the hot and the ground, it should trip the GFCI. If you test
between the hot and neutral and get 120, it should work. Try another lamp

This is only vaguely related, but I bought a partial DC to AC
converter at a hamfest. Rated at 75 watts. It was missing the center
button and maybe the fuse from the plug that fit into the cigarette
lighter. The guy had dozens of them with the same problem. Four
dollars each iirc.
I managed to find a button and a spring, and decide the fuse wasn't
missing, and I tried it with a 15 watt table radio. The green led
turned red every time and nothing came out of the radio. I tried
several times, same result.
So I found a 5 watt radio and that worked. They I tried 40, 60, and
even 75 watt regular incandescent bulbs, and the 75 cycled bright and
then a bit dim, but the other bulbs were good.
Now I really didn't understand why the 15 watt radio didn't work, and
I tried it again, and it did.
Who knows why!
Now I'm not sure I have any use for this, but maybe. I have a bigger
converter somewhere, but this is small enough to keep in the car. I
think it was made for a laptop computer -- it has the brand of a
computer company -- so there should be good voltage stability, except
at the full 75 watts. Or maybe not. Maybe the laptop does its own
Why not just replace the receptacle? I am thinking glassed-in porch
might have more temperature extremes, condensation, etc. and there might
be corrosion on the little contacts that hold the plug in - the sharp
probes of your Fluke might scratch through it but a plug might not. Or
the contacts might have lost their "spring" - I have a few like that in
my house. (down from many when I moved in.) Either way, probably worth
it to just replace it with a good spec-grade receptacle and be done with it.
Unless this is physically the last device on the circuit, the fault is
almost certainly with the receptacle itself.
replace "fly" with "com" to reply.
110 volts in relation to what? In other words, you are connecting one
probe to the hot wire or hot prong in the outlet, but what are you
connecting the other lead to? Are you connecting it to the neutral
(white wire, or LARGE prong hole), or to the grounded outlet box or
ground wire? If you are connecting to the ground or box, you could
have a faulty neutral. Pull the outlet out of the wall, and test from
the hot (probably black wire) to the white wire. DO YOU HAVE 110V?
Now test it from the black wire to the metal box (if its metal) or to
the bare wire. Now DO YOU HAVE 110V?
You should have 110V BOTH WAYS. If not, you got a bad wire somewhere.
It's uncommon, but something inside the outlet might be broken.
Rather than screw around with it, spend a buck and replace it, since
it's already out of the wall anyhow. Outlets wear out over time so
replacement is a good idea.
Last thought, did you plug you lamp into BOTH the top and bottom plug
on the duplex outlet? You cound have one of those little jumpers
broken (in which case, replace the outlet).
I'd like to hear what you find out. Post a followup.
