GFCI Circuit Breaker Problem repair question? Followup?

Question

Thanks for the tips to all who replied. A followup. Most of you suggested there is likely an open between neutral and GFCI at breaker box. If there is a break, can it still show voltage at any of the related outlets between the neutral and ground to be still 120V? Where is this voltage coming from, if there is a break?

I will still go ahead and check for discontinuity from outlets to GFCI at breaker. This sounds like a good suggestion to check for.

Tnx

Answer 1

Your test:

a. 0V. Ph. - N,  

b. 120V. Ph. -G.,

c. 120V. N.-G.

You've got more than one problem.

First, make sure everything is unplugged,

all switches on the circuit open.

Test again, if  'c.' is not now zero, you've got both

a short, and an open neutral.

'c.' should not happen unless there's some Ph. - N.

connection. - Find it.

'a.' should not happen unless the neutral is open

somewhere. - Find that.

Sorry not to be of more help, but you don't say

whether this is a new installation, or a working

one that 'quit`.

If it's the first case, check all your work.

Check that the breaker to neutral connection is good.

If the problem doesn't appear, don't neglect to

check for a faulty device.

If it's the second case, look at the devices first.

Answer 2

YOU CAN GET A VOLTAGE BETWEEN HOT AND NEUTRAL OR HOT AND GROUND

since neutral and ground are together in your main panel

you should get 120 between both.

electricity travels the path of least resistance.

you should get a continuity tone between neutral and ground

no matter where you test light or receptacle.
