I have a problem that confuses me. I have 1 circuit going to a
junction box and in the junction box there is a line going down to 1
outlet which works fine, the there is another line coming from the
same junction box on the same circuit going down to another outlet.
The problem is the second outlet was working and somebody plugged
something in to the outlet and tripped the circuit breaker. They then
reset the circuit breaker and now the second outlet will not work
however the first outlet does work fine. What could be causing this?
Did you measure the voltage at the wires on the defective outlet, or
just plug something into the outlet to determine if it worked? You must
take some measurements rather than assume it is reaching a particular
point. That goes for the splice in the "Junction box" as well.
You may well need to replace receptacle. Turn off power at breaker,
_make sure_ it is off by testing at good outlet, then pull out bad
recep, check connections there and also at junction box. If you see
signs of overheating/ discoloration on recep, replace it. If you read
here for a while, you will see a lot of advice to use screw terminals
instead of the quick n easy but less reliable back stab connection
Did you see this happen? Not counting ground faults that cause a
breaker to trip, if a breaker trips it is because there is too much
current going through the wires. This can damage the outlet
(receptacle). This is especially true if the device is on, or the
short is present whether the device is on or off. So the receptacle
could be damaged inside. That is, there might be proper voltage
reaching the receptacle, but the prongs of plugs can't make good
contact with the slots inside the receptacle, the device still won't
I asked because if you had seen it happen you would have heard noises
or seen sparks and you might know that they came from the outlet, and
not from whatever was plugged in. If you saw spark or heard noises
from teh outlet and now it doesn't work, a good chance it's the outlet
that is bad.
Thanks for all the replies guys. I found out what was wrong. I went to
the junction box and took the wire nut off the hots and the hot to
that particualr outlet was not stripped back far enough and also not
making contact with the other hots. However what I want to know is why
would that cause it to trip the circuit and how come it worked for a
while before it tripped the breaker? ThAnKs
The breaker most likely tripped because what ever was being plugged in
was bad. Has anyone tried to re use whatever that was?
I am guessing that the wire probably got a nick in the copper when the
insulation was stripped. When the circuit was overloaded the wire
melted at the week spot and lost contact with the wirenut.
If this was me, I would be concerned why it happened. The breaker
tripping propbly protected the home from the wires overheating in the
walls and causing a fire. Thank God For Good Breakers. :D If the
same person who did the junction box wiring, did any other, please
have the work second checked. After I wire up some wires under a
twister, it's solid.
Becareful with Electricity, I believe it's the second major cause of
BTW, thanks for the followup, those following thread appreciate it.
