Electrical changes 120 volt ac

Yep, the 120vac was also relocated and rewired. Acess to ac circuit breakers are from rear storage area. Several circuit breakers were added and GFIC was retained....Frank

Requesting GFIC Breaker Help

For sure, I am stumped on this one.

On the 1978 31’ Sovereign trailer “redo” I have run into a real conundrum---forget any work I have done - all of these problems are "upstream" of the new wiring, so this would have been (I think) a pre-existing condition. With the GFIC breaker installed and powered up, I get 121 volts between the hot and neutral - 0 volts between the hot and ground.... and 121 volts between the neutral and ground – circuit box at the house (master panel) has been running 122 volts lately – so I am getting “full voltage” to the end of the circuit wiring – including the neutral (of the GFI circuit) with the GFIC breaker installed.

It gets more interesting...

with the GFIC Breaker in the "Off" position I get 87 volts between the neutral and ground, and 53 volts between the hot and neutral ...

The same numbers were experienced with the original GFIC Breaker, so I (foolishly) pitched it (non-retrievable), and bought a new one ($40) - I get identical numbers with the new one - I'm just $40 poorer - lost an hour of my life running to the closest HD store and burned two gallons of gas to get there and back while purchasing the new GFIC Breaker. Worst of all, I have been playing hide and seek with this gremlin for going on three days now - have done other things in the meantime, but I am starting to get obsessed with the problem.

All other (non-GFIC) breakers are apparently operating properly, and the ohm meter shows infinity between both hot to ground, and neutral to ground...and no conductivity between hot and neutral. Separate (and isolated) connector blocks for neutral and ground in the breaker box.

This is a GE breaker box with all GE breakers installed. Both the old and new GFIC Breakers “threw” when the test button was pressed.

The GFCI circuit services the Univolt only (I think, I will confirm that tomorrow), so I am contemplating pitching the GFCI Breaker, installing a conventional breaker in it's place, and replacing the Univolt receptacle with a GFI Receptacle.

Any comments on just forgetting the GFIC in this case and going with a straight up 15 amp circuit breaker in the panel?

In summary,

1.Is the GFIC Breaker doing what it is supposed to?
2.Would installing a conventional breaker and a GFIC receptacle afford the same level of protection?
3.Do I even need GFIC protection in this case? (Univolt only.)

Thanks

When you say between the x and x where are you testing, in the panel at the breaker poles, on the service end of that breaker's wire, or somewhere else.

Do a forum search for "Circuit breaker box" and read my threads on "Electrical Problem Again" and "30 amp power cord". Look at my breaker box and see if wiring is anything near what you have. Also, I found one of my breakers was not working correctly thereby allowing current in at a lower rate when in the off position or even in the on position. You would have to read the entire thread to see the problem I had. One problem was the short in the 30 amp power plug, the second was someone who was helping wired in a jumper from ground to neutral (something you don't want to do in a GFIC circuit particularly in a trailer). I got some strange readings on the voltmeter while testing all the wiring until I found the problem. Do you have a service manual showing wiring going into the box?

To sort thru any electrical problem, the key to solution is care. Start at the beginning, where power comes into main circuit breaker box. Carefully begin to test each power leg as each breaker is powered. Wild power voltages are being affected by some device. Last month, I spent nearly a day, in a commercial business looking for an intermitted neutral. In a last desperate act, a call was made to the power provider. The local outside transformer had an intermitten connection at the neutral. Many electrical problems are difficult because of not carefully testing and taking for granted. There is always a reason for voltage changes. Frank

87MH,
FrankR helped me with the electrical problem I was having in my '77. If it wasn't for him, johnhd and a few others, I would not have found the solution.

Frank, long time, no see.
