i'm putting together my to-do list for memorial day at the cabin and once again i need to replace several outdoor gfi outlets. the indoor gfi's do just fine but i dont seem to get more than 1-2 years out of the outdoor gfis before they fail. when they fail the set/reset buttons are frozen into place and won't "click" in and out of place. our electrical system consists of a generator and an inverter/battery bank. so my questions for the forum are - does extreme cold affect gfi's? are some invertors or generators incompatible with gfi's? are gfi's even worth the trouble at a cabin? are there some brands of gfi's that work better outdoors, especially in alaska? does the mode of failure indicate that water is probably getting into the gfi?
i've looked on the internet and the answers to these questions are all over the place. i'd appreciate any feedback from people with actual alaska experience.
