Hello.
I have a 40amp GFCI installed in my panel that powers my hot tub outside.
The hot tub is fed with 45 feet og 6/3 copper wire.
The tub calls for a 40 amp GFCI breaker.
So far so good.
The hot tub works great most of the time. However, once every week or so the GFCI will trip. Reset it and all is good for another week or more.
Today I chose to inspect the GFCI wiring in the panel. All connections are tight, but I did notice that the ground wire installed on the GFCI neutral to panel lug is of a different gauge than all the rest (6/3) the ground wire is 8 gauge.
My question is this. Will the smaller gauge neutral wire cause the breaker to falsely trip on occasion? Or should I replace with a larger GFCI like 50amp that is more suited to the wire size?
FYI the test button works like a charm.
Thanks
Paul
