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?
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.)
