hot tub gfci tripping
Have a Hot Springs hot tub, 110 power. We moved about 2 years ago and I ran a dedicated 110 line to a 20amp breaker we added to panel (which is what man. recommends and the way it was wired in our last home). The GFCI is part of the plug coming from the hot tub, and located in a weatherproof box with cover (that came with tub). Lately, about once every two weeks, the GFCI will trip. It doesn't seem to be related to using the tub. I can't tell if it is related to getting wet, although it shouldn't be where it is located. Am I missing something? Actually, this started a couple months ago and at one point the original GFCI plug that came with the tub actually stopped working all together and I had to replace. Any thoughts would be appreciated.

Can you correlate the tripping with anything? Rain? Humid days? Windy day?
Most likely, moisture is getting in somewhere, not necessarily in the box containing the GFCI. Could be at the hot tub, or perhaps the cable is damaged somewhere. What kind of wire or cable did you use? Is any part of it buried? Where is the hot tub located? Are any of the electrical connections subject to the weather (even if in a so-called weatherproof box)?

John:
I appreciate the reply. I doubt the line from the panel to the outlet is damaged, but I'll check. I'll also take the panel off the hot tub and make sure there is no damage or chance of water getting in on other end. If none of those are the cause, my last thought is that even though the GFCI box has a gasket where it is mounted, I should caulk around the box to make sure water is not getting behind the gasket somehow.
p.s. nothing is buried and I suspect I used 12/2 or 10/2. I usually err on the side of being oversized.
