I have a receptacle that has suddenly gone dead. The circuit breaker is
fine and everything else on that circuit works. Using a two-prong tester
the receptacle appears hot. Leaving the tester inserted into the
receptacle, with light glowing, plugging in a working lamp into bottom
receptacle the tester's lamp goes off. Remove the lamp (or turn it off) and
the tester glows again. What is up with this? Thanks for any and all
help. -Jeff Linder ( email@example.com)
What you discribe sounds like a loose connection (high resistance) someplace
in the wiring to that recepticale. Just enough current is getting through
the poor connection to operate the test instrument but when you try to draw
a higher current, nothing gets through.
You should check the connection in the receptical you are testing. Also,
household recepticales are often 'daizy chained', one outlet after another..
Any receptical in the chain, between the circuit breaker and the problem one
could have a loose connection..
I had a similar problem and after checking and replacing three suspected
recepticales, I found the problem was a arched and burned contact where the
circuit breaker clips onto the panel buss bar...
Both the breaker and the buss bar were damaged and not only did have to put
in a new breaker, but I had to move it to an empty location in the panel.
I'd fogotten to mention that I already installed a new receptacle (yeah,
they're real cheap). But your theory sounds plausible and I'm going to
replace all the receptacles in this circuit and check everything else in
this circuit. Let's see if this works. Thanks. In your case, how did you
discover that your probem was the burned contact where the circuit breaker
clips onto the panel buss bar? Process of elimination? -Jeff
I had traced the circuit problem back all the way to the breaker panel and
was ready to replace the breaker. When I pulled the breaker out of the
panel, it was obvious that it had been over heating and arcing between the
contacts and the buss bar.
There was so much arc splatter on the buss bar that I couldn't clean it off
with a file.. Total loss of that slot.
