Rick - It could very well have been the rain. I smoke under cover but we do get some high winds and hard rain (except this year - bone dry) and never had a breaker trip. HOWEVER! We have have the occasional power outage/blip, only lasts a couple of seconds but it is enough to require resetting items with a digital circuit board including my smoker. Fortunately our outages are early morning/late afternoon. Never had an outage during a smoke.
