Heat Tape tripping GFCI Intermitently
I have 3 year old heat tape on my roof. About 150 feet of it. This spring it started tripping the GFCI after a minute of being on. It was consistently tripping the GFCI.
My plan was to wait for the weather to warm up, reproduce the tripping of the GFCI and then call the electrician. However the GFCI never tripped again. I waited until we had a soaking rain, but the heat tape worked and never tripped the GFCI all day.
What are my options besides replacing all the heat tape? (Very expensive)
