Circuit breaker on Master Power Switch Popping

I have narrowed this down to the DLX Security / Pro Air panel. It has pump in, pump out, security, and acc buttons on it. This is an intermittent issue during rain events so definitely related to significant moisture events. I have replaced the DLX panel recently as my security system was activating on its own, again during rain event. Just figured it was the panel and the new panel seems to have fixed the security system issue. Now I have the breaker popping. Yesterday, I was fishing in the rain and the breaker popped. Tried a couple resets and it would still pop. Decided to unplug the DLX panel just to see if I could isolate the issue and the breaker reset and was able to continue fishing and breaker never popped again. After a night in my heated shop, I replugged the DLX and the pump in and pump out pumps worked fine. Master power CB never popped. I don’t think there is anything wired to the acc button. Any ideas what may be causing an issue like this? I’m not exactly sure all the components of the security system so not sure what to look for there? Could moisture be getting into one of the compartment lights and shorting the master power switch CB? Any help and guidance appreciated. 2013 Cougar
