Problem with Neutral Connection
I am new here and have not had much time to look around. So I apologize if this issue has been covered before.
Problem: 120v 20amp circuit stopped working out of the blue.
Receptical: Hot to ground = 120volts
Hot to Neutral = 99volts
Ground to Neutral = 50Mohms
Question: Is this an indication that the neutral is floating or comprimised? It is my understanding that the readings should be as follows:
Hot to Ground = 120volts
Hot to Neutral = 120volts
Ground to Neutral = 0Ohms.
Any suggestions would be greatly appreciated. I am planning on opening the panel tomorrow. However, seems unlikely that there is a problem seems everything has been working for 5+ years.
Thank you in advance for suggestions or comments.
did you test with the digtail voltmeter ??
If so you may end up reading ghost voltage and the way you descrbing i am more leaning you have bad netural connection somehwere.
a very simple test is take a table lamp just plug it in and you should see it lit up or not a very simple go / no go test.
before you start working on the connection i really strongly advise ya to turn off the breaker for that circuit [ if mapped out or marked ]
it can be bad back stabbed repectale or bad wirenut connection [ backstabbed repectales are most common for netural conntion dropped out ]
Always start at the source. I had one today that was installed in 2001. The neutral connection at the bus had never been sufficiently tightened and it chose Friday to stp working.
At least 1/2 the time it is at a feed thru receptical that has been backstabbed. Use logic and trace the circuit path.
SOME of your circuit may still be working so I dentify the breaker, turn it off and check all outlets/lights. If some are working you know where it stopped.
Thanks for the responses. Turns out the Netural wire had arc'd within the SP compromising the connection. Now, I guess the question is how did this happen.
Loose to begin with??
Brother messing with the GFCI outlet?? (His history indicates he should not mess with electricity)
However it happened I was able to reterminate and verify its operation. Thanks again for the suggestions.
